Concierge Longevity Medicine & Advanced Urgent Care — Southern California
Optimize your health.
MEDHERO is a concierge longevity practice built for people who want more than a 10-minute appointment, a vague set of lab values, and a referral they didn’t need. We go deep. We stay with you. We keep you well.
MEDHERO
Your doctor has
10 minutes.
We have as long
as it takes.
Your health deserves more than a quick appointment and a generic plan. MEDHERO is a state-of-the-art medspa and wellness center serving Southern California from two convenient locations in San Clemente and Carlsbad (La Costa). Founded by Dr. Greg Moreno, MD, and Dr. Keith Yablonicky, MD, our practice was built on a simple belief that true wellness goes far deeper than treating symptoms.
“You deserve a physician who knows you well enough to see what’s changing — before it becomes a problem.”
Advanced urgent care, pediatric care, hormone replacement therapy, personalized wellness plans, and medspa services are all available, led by physicians who genuinely care about the communities they serve.

What Sets Our Urgent Care Apart From the Rest
At MEDHERO, our urgent care team is led by board-certified emergency physicians, not general practitioners or walk-in clinic staff. We treat non-life-threatening conditions with the same level of skill and equipment you’d expect at a hospital, without the long wait.
We operate seven days a week, from 8 AM to 8 PM, at both our San Clemente and La Costa locations. Walk-ins are always available, and online booking is offered for added convenience.
How Our Emergency-Trained Doctors Change the Standard of Care
Our physicians completed their residencies at the LA County+USC Trauma Center, one of the most demanding programs in the country. That background means we handle complex cases with confidence and precision that most walk-in facilities simply cannot match.
Our diagnostic capabilities include:
- Digital X-rays with same-day results
- A CLIA-accredited on-site laboratory
- EKGs and hospital-level IV medications
- ImPACT® certified concussion screening
Treating the Conditions That Catch You Off Guard
A sports injury, a bad infection, a child’s high fever — these things happen fast. MEDHERO is equipped to handle a wide range of conditions on the spot, so you spend less time waiting and more time recovering.
Conditions we treat include:
- Lacerations, fractures, and dislocations
- Asthma attacks and respiratory infections
- Skin infections and rashes
- Sprains, strains, and rotator cuff injuries
- Pediatric sick visits, physicals, and immunizations
Our MEDHERO team lives and works in this community, and taking care of our neighbors is what drives everything we do. Our on-site pharmacy means you can leave with your prescription the same day.
Aesthetics Treatments Designed Around Your Skin Goals
MEDHERO aesthetics services go beyond surface-level results. Our treatments are overseen by experienced physicians and performed by highly trained clinical staff. You receive medical-grade care tailored to your specific skin concerns.
Our team serves both La Costa and San Clemente, offering a broad range of treatments across both locations. Not all services and equipment are the same at each site, so we encourage you to call ahead to confirm availability.
Real Results Backed by Medical-Grade Technology
Our aesthetic treatments use advanced technology to target concerns that skin care products alone cannot fix. MEDHERO uses lasers (erbium, thallium), radiofrequency, microneedling, Intense Pulsed Light (IPL) or RF/microneedling equipment to treat all your skincare concerns. These tools address everything from tone and texture to deeper structural concerns like collagen loss.
Our laser and resurfacing treatments include:
- IPL/Laser for age spots, discoloration (browns/reds), small capillaries or veins
- and uneven skin tone
- 1540 fractional erbium laser for texture and fine lines.
- Multiple modalities for collagen stimulation
- Acne scar and stretch mark revision
- Spider vein reduction
How Injectables and Skin Renewal Work Together
Injectables are one of the most effective ways to restore a refreshed, natural appearance. Our team offers neurotoxin treatments and dermal fillers targeting areas like the lips, cheeks, jawline, and forehead. Results from fillers can last 12 to 24 months, and neurotoxin results appear quickly with effects lasting up to 4 months.
Our injectable and skin renewal services address:
- Fine lines, frown lines, and crow’s feet through muscle relaxation
- Volume loss in the cheeks, lips, and jawline through hyaluronic acid gel
- Acne scars, enlarged pores, and stretch marks through microneedling
- Skin laxity and deeper wrinkles through radiofrequency energy
- Melasma and hyperpigmentation through advanced depigmentation treatment
True skin health is built over time with the right treatments and the right team behind them. Our providers at MEDHERO take an honest, personalized approach to every visit so your results reflect what actually works for your skin, not a one-size-fits-all plan.
A Health Spa Built on Longevity and Personalized Care
Most health spa experiences stop at relaxation. Ours start with a deeper look at how your body is actually functioning. At MEDHERO, every service is designed around the idea that looking and feeling your best requires more than a single treatment. It requires a full picture of your health, built around your labs, your body composition, and your personal goals.
Our physician-led team takes a proactive approach to wellness, addressing what conventional medicine often overlooks. We offer a comprehensive menu of longevity and aesthetic services tailored to each individual.
What Your Body Data Is Actually Telling You
Understanding your health starts with accurate measurement. MEDHERO uses industry-leading diagnostic tools to go beyond surface-level assessments and give you a true baseline. Deep laboratory analysis, Dexascans, and VO2 max testing are at the core of our evaluation. Our DEXA body composition scan takes just 10 to 20 minutes and produces detailed, limb-specific data that becomes the foundation of your personalized wellness plan. Dexascans look at muscle, bone density, and fat – not just analyzing how much but where these tissues are on your body (around your organs (Viseral fat), in your limbs, thighs, belly, etc.
Our body composition and fitness testing reveal:
- How your cardiovascular capacity compares to longevity benchmarks
- The exact number of calories your body burns at rest
- Muscle group strengths and areas that need attention
- How your body regulates blood sugar throughout the day
- Where your lab values stand relative to optimal health ranges
- Bone density
- Muscle on your limbs – direct predictor of longevity
- Fat – where your fat accumulates puts you at risk of cancer, vascular disease, and more.
Getting Ahead of Health Issues Before They Become Problems
Reactive care waits for something to go wrong. Our approach identifies imbalances early so you can make informed decisions before a small issue becomes a larger one. MEDHERO longevity consultations are 90-minute, physician-led sessions that review your health history in depth and give you answers to your questions.
Our proactive approach includes:
- Identifying hormonal and metabolic imbalances before symptoms escalate
- Reviewing lab work in depth to catch issues that conventional checkups often miss
- Building individualized wellness plans based on your full health profile
- Regular progress reviews to keep your health trajectory on track
- Honest referrals to outside specialists when that serves your best interest
- Discussing and reviewing true longevity benchmarks like VO2 max values, dexascans, cardiac angiograms (CT-based), and more.
Your health is a long-term investment, and our team treats it that way. Our team is deeply invested in the communities we call home, and that shapes every recommendation we make.
Weight Loss Programs That Address the Root Cause
Losing weight is rarely as simple as eating less and moving more. Hormonal imbalances, metabolic slowdowns, and blood sugar dysregulation can all work against your progress without you even knowing it. Our physicians dig into the underlying factors that make weight loss difficult, so your plan is built on real data rather than guesswork.
At MEDHERO, every weight loss program begins with an extensive laboratory panel and a full results review with Dr. Yablonicky, a board-certified MD. That evaluation shapes everything that follows, including whether medication, hormone adjustments, or a combination of both is the right path for you.
How GLP Medications Actually Work in Your Body
GLP stands for glucagon-like peptide, a naturally occurring compound that plays a key role in regulating blood sugar. GLP agonist medications work by enhancing insulin secretion through the pancreas, slowing gastric emptying, and signaling the brain to reduce appetite. The result is that patients naturally eat less and lose weight steadily over time. Currently, we have GLP-1s, GLP-2s, and GLP-3 medications, with likely new versions coming.
Our available GLP medications at MEDHERO include:
- GLP-1 generally refers to Semaglutide, administered as a weekly subcutaneous injection, offering between 15-20% body weight loss (on average).
- Tirzepatide (GLP-2), which acts on two receptors and offers up to 25% of body weight loss with fewer side effects,
- GLP-3 or Retatrutide is a non-FDA-approved peptide compounded from trusted pharmacies with the hope of better weight loss with less muscle and bone density loss. All options start at low doses and increase gradually over several months
- A maintenance phase was introduced around four months into treatment
- Careful monitoring of side effects at every dose adjustment
- The largest downside to these medications are muscle and bone density loss. This is why you must be under the guidance of a physician to help mitigate the negative effects of GLP medications.
Weight Loss and Body Sculpting Treatments for Women/Men
Men’s and women’s bodies hold and release weight differently. Hormonal shifts, a slower resting metabolic rate, and muscle loss all influence how effective any weight loss program will be. Our RMR test measures the exact number of calories your body burns at rest, giving us a precise starting point that accounts for these gender specific factors before any treatment begins.
Our weight loss support includes:
- Full endocrine and hormone panel to detect underlying imbalances
- DEXA body composition scan for body fat percentage and muscle mass details
- Thyroid and testosterone evaluation as contributing weight factors
- Limb-specific body density measurements
- Noninvasive body contouring to address areas resistant to fat loss
Sustainable weight loss takes more than a prescription. Our team at MEDHERO stays involved at every stage, making adjustments based on how your body responds and keeping your long-term health at the center of every decision.
Testosterone and Hormone Therapy That Works With Your Body, Not Against It
For decades, women’s Hormone Replacement Therapy (HRT) has focused on Progesterone and Estrogen, ignoring Testosterone – a very important hormone for women. Men’s HRT has focused on Testosterone alone. Certainly, TRT (Testosterone Replacement Therapy) is the most important for men, but estrogen levels are vital as well. Declining testosterone hormone levels are not just a men’s health issue, and they are not simply an unavoidable part of getting older. Both men and women experience the effects of shifting hormone levels, and those changes affect energy, sleep, body composition, mental clarity, and overall quality of life.
At MEDHERO, the hormones we prescribe are chemically identical to the ones your body has always produced (Bioidentical hormones). There are no synthetic formulas and no horse-derived hormones. Your treatment plan is shaped by your unique biology, health history, and personal goals.
What Declining Testosterone Does to Your Daily Life
What feels like ordinary stress or the effects of a busy life may trace back to suboptimal hormone levels. Our MEDHERO team looks at the full hormonal picture and uses that information to determine exactly where imbalances exist before any recommendations are made. Low testosterone also directly impacts cardiovascular capacity, which is why we use VO2 max testing as part of our evaluation to measure how efficiently your body uses oxygen and track improvements throughout treatment.
Symptoms commonly linked to low testosterone include:
- Poor concentration and mental fog
- Loss of muscle mass and increased body fat
- Low libido and reduced energy
- Disrupted sleep patterns
- Mood changes and decreased motivation
Personalized Hormone Plans for Men and Women
Testosterone therapy is not one-size-fits-all, and it is not only for men. In women, testosterone is one of the most biologically active hormones in the body, and even small adjustments can produce meaningful improvements in energy, libido, and overall vitality. Our approach at MEDHERO accounts for your age, symptom history, lab results, and health background to build a plan that fits your body specifically.
Our hormone planning process considers:
- Which hormones are deficient or imbalanced based on your lab results
- Whether female or male hormone pathways need to be addressed
- What supportive hormones may benefit your overall hormonal health
- How your delivery method preference fits your lifestyle and treatment goals
- Whether additional vitamin or nutrient support is needed alongside hormone therapy
Testosterone therapy done right is safe, effective, and deeply personal. Our practice takes the time to get it right, and our patients feel the difference.
Remember, ALL hormones are important, and until they are balanced and optimized, you will not be your best. Most primary doctors will just tell you if they are normal or abnormal, but this is too broad and generalized – you want to be OPTIMIZED.
Health Consultations Built Around Living Longer and Feeling Better
At MEDHERO, every visit begins with an in-depth conversation about your personal and family health history, current concerns, and long-term goals. Our health consultations are built around a standard that takes the time to understand how your body is aging and what can be done to optimize it.
We believe true longevity starts from within. That means going beyond surface-level assessments and using advanced diagnostic tools, intensive lab evaluations, and specialized testing to build a plan focused on extending your healthspan, not just your lifespan.
The Care You Receive Starts With Knowing You
Our board-certified physicians bring the training and experience to connect seemingly unrelated symptoms and identify imbalances that accelerate aging and affect long-term health. Every detail of your health history is considered before a single recommendation is made, so you leave with clarity and a clear path forward.
Your consultation at MEDHERO may include:
- A comprehensive review of your personal and family health history
- Intensive lab evaluations reviewed in full with a board-certified MD
- DEXA body composition scanning for fat, muscle, and bone density data
- VO2 max and RMR testing to assess cardiovascular and metabolic function
- Genetic testing to inform long-term health and treatment decisions
Turning Your Results Into a Plan That Works
Lab results, body composition data, and fitness testing all tell a story about where your health stands today and where it is headed as you age. Our physicians connect those data points to build a personalized wellness plan that targets your specific concerns, whether that is hormone optimization, weight management, longevity, or a combination of all three.
What your personalized plan may address:
- Suboptimal hormone levels affecting energy, sleep, and body composition
- Metabolic factors contributing to weight gain or difficulty losing fat
- Nutritional and supplement needs identified through lab work
- Anti-aging and longevity strategies tailored to your biology
- Aesthetic concerns approached through a medically informed lens
Real results come from understanding the full picture. At MEDHERO, every recommendation we make is built on real insight into your health, and our team stays invested in your progress every step of the way.
Meet The Doctors
MEDHERO was founded by two board-certified emergency physicians who share a vision for what modern healthcare can be. Dr. Greg Moreno, MD, earned his medical degree from the Keck School of Medicine at USC and completed his emergency medicine residency at LA County+USC Medical Center, going on to launch our practice in 2015 as Medical Director of our San Clemente location.
Dr. Keith Yablonicky, MD, attended Loyola University of Chicago on a Naval scholarship, served five years as a U.S. Navy Flight Surgeon, including a wartime deployment to Iraq, and also completed his residency at LA County+USC. He now directs our La Costa location and heads our hormone optimization and weight loss programs. Alongside them, our dedicated team of physicians, physician assistants, and licensed aestheticians brings the same commitment to exceptional, individualized care at every appointment.

The MEDHERO peptide
approach: data before protocol.
We don’t start with a peptide and work backward. We start with your biomarkers, your goals, and your full health picture — then ask what, if anything, the peptide landscape can meaningfully offer. That’s a different conversation than what’s happening on most forums and in clinics running peptide programs as a revenue line.
01
Baseline labs first
IGF-1, hormone panels, metabolic markers, and organ function established before any protocol begins.
02
FDA-registered sourcing only
All compounded peptides sourced exclusively from 503A/503B compounding pharmacies — never unregulated online suppliers.
03
Honest about the evidence
GLP-1s: strong randomized trial data. Other peptides: promising preclinical data, physician judgment required. We tell you the difference.
04
Ongoing monitoring
Labs rechecked at protocol intervals. Adjustments made on biomarker response, not just symptom report.

FAQs
How do I know which services are right for me?
MEDHERO physicians take time to review your health history, goals, and lab results before making any recommendations. There is no pressure to pursue any particular service; our focus is entirely on what makes sense for your individual needs. If you are unsure where to start, a wellness consultation is a great first step to map out the right path forward.
How often should I expect to come in for treatments?
Visit frequency depends entirely on the service and your personal health goals. Some treatments, like IV hydration therapy or hormone optimization, may involve regular follow-up appointments to monitor progress and adjust your plan. Our MEDHERO team will walk you through a realistic schedule during your consultation so you always feel informed and prepared.
Do I need an appointment, or can I walk in?
Walk-ins are welcome at both our San Clemente and La Costa MEDHERO locations for urgent care services. For wellness and medspa visits, scheduling ahead ensures you get the focused time and attention your care requires. You can book online or give us a call to find a time that fits your schedule.
What should I expect during my first visit?
Your first visit to MEDHERO begins with a thorough review of your health history and goals, and may include lab work or body composition testing, depending on the service you are pursuing. Our physicians take the time to fully understand your situation before making any recommendations. You can expect a comfortable, professional setting where your questions are encouraged, and your concerns are addressed with care.
What services are available at each location?
Both our San Clemente and La Costa (Carlsbad) locations offer core urgent care and wellness services, but not every treatment or piece of equipment is available at each site. La Costa serves as our primary hub for medspa and aesthetic services, while San Clemente offers a strong focus on urgent care and healthspan services. We recommend calling ahead to confirm availability at your preferred MEDHERO location before booking.
