Originally developed to help manage type 2 diabetes, Semaglutide has proven effective in reducing body weight by mimicking GLP-1, a hormone that targets appetite control areas in the brain. This effect makes it easier to reduce calorie intake, which can lead to significant, sustained weight loss.
At MD Total Wellness, our top priority is your success.
Here’s why Fullerton residents trust MD Total Wellness:

Choose MDTW because our providers bring something most wellness clinics can’t: over 20 years of shared clinical experience, starting in bariatric surgery and now in functional wellness. We’re physician-owned, in-person, and deeply invested in your results — not a telehealth company, not a franchise.

Schedule a free consult to experience the difference.
Consider GLP-1 medication if you’ve been unable to lose weight and keep it off, and if your weight is impacting your quality of life. The GLP-1 medications work in the body like your body’s natural GLP-1, which is an intestinal hormone that regulates appetite. The GLP-1 medications, semaglutide and tirzepatide, are very effective at decreasing appetite and cravings, and make substantial weight loss possible. Risks are low and the medications are well tolerated. When the medications are used as a tool for behavior change, they can help you to not just lose weight, but to maintain weight loss long term.
MDTW’s GLP-1 weight loss program combines quality-vetted compounded semaglutide or tirzepatide with physician oversight, personalized dosing, nutrition and lifestyle guidance, and body composition tracking — all at prices below brand-name alternatives.
What sets us apart is the depth of experience behind your care. Dr. Oliak performed over 3,000 bariatric surgeries before transitioning to GLP-1 weight loss — giving him a clinical understanding of weight management that most GLP-1 providers simply don’t have. Together, he and PA Mollet have specialized in weight loss for over 20 years and helped thousands of patients achieve lasting results. Schedule a free consult to get started.
Studies show that patients lose an average of 15% of their weight with semaglutide, and 21% of their weight with tirzepatide. These are averages – individual patients can lose more or less than the average. Our experience has been that these medications, when combined with good eating and exercise habits, enable most patients to lose substantial weight.
Compounded semaglutide and tirzepatide contain the exact same active ingredients as the branded medications, but are available for lower prices than the branded medications.
Schedule a free consult in our Brea office with David Oliak, MD, or Allison Mollet, PA-C, by calling our office or sending us an online contact form. If you are a candidate, get started with treatment the same day as your consult.
No — and here’s why that works in your favor. By not billing insurance, we eliminate prior authorizations, surprise bills, and the time pressure that rushes most medical appointments. You get unhurried, focused care with a provider who actually knows you. We accept all major credit/debit cards, HSA and FSA, and offer 0% financing for treatment packages.
Our prices for hormone therapy and weight loss are listed on our individual service pages. We offer transparent monthly pricing with no time commitments, so you cancel anytime. For procedures, such as Alma TED, EmSella, and EmFemme, price depends on the number of treatments prescribed, and is determined after your consultation.
