About MD Total Wellness

The quick facts, for you and for the search engines.

We treat the root causes of how you feel, not just the symptoms. That spans medical weight loss with GLP-1 medications, men's health and testosterone therapy, women's hormone and intimate health, thyroid, peptide and NAD+ therapy, hair restoration, and non-invasive treatments for pain, recovery, and strength. If you want the full picture before anything else, a comprehensive evaluation looks at how your body is actually working and turns it into a personalized plan. Physician-led and in person, in Brea.

Yes. Peptide therapy is one of our core services, used for recovery, skin and hair, focus, energy, and hormone optimization. Every peptide we provide is prescribed by a physician and compounded for human use by a licensed U.S. pharmacy, then shipped to your door, which is a different thing entirely from the research chemicals sold online. Depending on your goal, you start with a focused peptide consultation, or with a comprehensive evaluation for growth-hormone peptides and broader plans.

We're in Brea, California, serving all of Orange County. The office is at 255 W. Central Ave, Suite 203, Brea, CA 92821, open Monday through Friday, 9am to 5pm. You can reach us at 714-671-2005.

Every page in this section is written and reviewed by the clinicians who provide the care, not outsourced and not summarized from other people's articles. Dr. David Oliak, a board-certified physician and surgeon, and Allison Mollet, PA-C, MSCP, a Menopause Society Certified Practitioner, review the guides in their areas, and they have practiced together since 2006. These are the explanations we would give you in the room, written down.

Start with a consultation. For most of our services that first consultation is free and often same-day: you meet a provider, confirm it's the right fit, and can begin that day. If you'd rather understand your whole picture first, book a comprehensive evaluation, a full panel of labs and an unhurried hour with your provider that becomes a personalized plan. Call 714-671-2005 or book online to begin.
