Over the past five years, I've helped patients across the San Diego area overcome stubborn weight loss plateaus and rebuild their vitality through functional medicine.

The secret is a holistic approach that combines hormone optimization, tailored nutrition and exercise plans, continuous accountability, and innovative medications like semaglutide (Ozempic, Wegovy) when they're the right fit — all grounded in empathy and science.

Here, weight loss is not just numbers on a scale. It's about a healthier, more vibrant you. I tailor my level of support to what you need. Whether you want me to push you every day or take a more gentle approach, I'll meet you where you are.

It's Not As Simple As "Eat Less, Move More"

Like many across the U.S., you may be trying to manage your weight through diet and exercise. Yet for over one-third of adults considered obese — and many more who are overweight — those efforts often aren't enough. Genetics, metabolism, hormones, and environment all push back. Hormonal imbalances intensify cravings, drive appetite, and make consistent calorie reduction nearly impossible through willpower alone.

Have you ever worked with a clinic that runs diagnostic tests to address hormone imbalances? One that monitors your blood sugar to keep you in fat-burning mode, tracks your protein intake and resistance training to protect muscle, and offers safe medical support when your biology needs the extra help?

That's what a real weight loss program looks like. My San Diego clinic leaves no stone unturned so you can lose the weight and keep it off for good.

How We Approach Weight Loss

Hormone and Thyroid Optimization

Identify and address the underlying issues affecting your weight, from thyroid dysfunction to insulin resistance to sex hormone imbalances.

Personalized Nutrition and Exercise

Build muscle and burn fat through resistance training and a way of eating that fits your life — not a generic meal plan.

Consistent Support and Accountability

Daily or weekly check-ins, photo logs, texts, and visits — calibrated to the level of support you actually want.

Innovative Medical Weight Loss

Safe, evidence-based medications like semaglutide (Ozempic, Wegovy) and tirzepatide for patients who need additional help breaking through biological barriers.

Semaglutide and Ozempic: Medical Support When You Need It

A patient recently told me that after starting semaglutide, it was the first time she could remember feeling free from the constant barrage of hunger, cravings, and binging. She could finally focus on the rest of her life without micromanaging every meal. The medication transformed her relationship with food.

That's what these medications can do when used correctly — not as a shortcut, but as a tool that quiets the biological noise so the rest of your plan can actually work.

What Semaglutide and Ozempic Are

Semaglutide is the active ingredient in Ozempic and Wegovy. It belongs to a class of drugs called GLP-1 receptor agonists, which mimic the GLP-1 hormone your body produces naturally. GLP-1 regulates appetite, insulin secretion, and blood sugar.

How They Work for Weight Loss

  • Suppress appetite by activating GLP-1 receptors in the brain, increasing fullness after meals
  • Slow gastric emptying so you stay satisfied longer
  • Stabilize blood sugar by enhancing insulin secretion and reducing glucose spikes that drive cravings
  • Reduce calorie intake naturally without the constant willpower battle

What Results Look Like

Clinical trials and real-world studies have documented weight loss of 15% to 20% of body weight for patients on semaglutide or tirzepatide — often surpassing what's possible with diet and exercise alone, and approaching the results seen with some weight loss surgeries. These findings are backed by research published in the New England Journal of Medicine and Diabetes Care.

The impact goes beyond the scale. I've seen patients normalize blood pressure and cholesterol, reverse fatty liver, improve arthritis and autoimmune conditions, resolve sleep apnea, and turn around early kidney and heart disease. Mood lifts. Anxiety drops. Energy returns.

Who Is a Good Candidate for GLP-1s?

GLP-1s may be a fit if:

  • You have a BMI of 27 or higher with weight-related health conditions
  • You have a BMI of 30 or higher and have struggled with weight loss despite real effort
  • You want a medically supervised, holistic approach rather than a quick prescription

During your consultation, I'll review your medical history and goals to determine whether semaglutide — or a different path — is right for you.

How We Use These Medications Differently

Most clinics hand you a standard dose and send you on your way. We don't.

  • Personalized dosing adjusted to your body's response
  • Lab work and ongoing monitoring to confirm safety and track progress
  • Body composition tracking so you lose fat, not muscle
  • Nutrition and exercise plans built to complement the medication
  • Ongoing support by text, email, and visit — so you actually stick the landing

We also keep costs reasonable: self-administered injections at home, available at a fraction of what many insurance routes end up costing once deductibles and copays are factored in.

What Working Together Looks Like

A Free 15-Minute Call

A 15-minute phone call to talk through your weight loss goals, health history, and whether semaglutide or another approach fits your life.

Comprehensive Initial Visit and Plan

A 90-minute deep dive into your full health history, prior treatments, lab work, and lifestyle. I build a personalized plan combining nutrition, exercise, supplements, and — if appropriate — semaglutide dosing and injection training.

Ongoing Monitoring and Adjustment

Regular check-ins by email, text, and follow-up visits. We track body composition, lab markers, and progress, adjusting your plan as your body responds.

Common Questions

What kind of support and accountability do you provide?

I'm available throughout your program by text, phone, email, and office visits. I adjust the level of contact to match what you need — some patients want daily check-ins with photo logs after workouts, others prefer weekly touch points. You set the pace, I show up.

Is there a follow-up plan after I hit my goal?

Yes. Maintaining weight loss matters as much as losing it. We build a sustainable maintenance plan with ongoing support, periodic check-ins, and the resources you need to keep your results long-term.

What are the side effects of semaglutide?

Mild side effects like nausea or constipation can occur early on and typically subside as your body adjusts. We adjust dosing carefully to minimize discomfort and monitor labs to ensure safety.

How long do patients stay on semaglutide?

Duration varies by patient and goals. Some use it for a defined window to break through a plateau; others stay on a maintenance dose long-term. We make that decision together based on your progress.
