About MD Total Wellness

At MD Total Wellness, we’re redefining what wellness care looks like in Orange County. Unlike online telehealth companies or cookie-cutter clinics, we’re a physician-owned medical practice offering personalized, results-driven care – in person, not over a screen. We believe in-person care is better care.

Dr. Oliak and PA Mollet have worked together since 2006 and founded MDTW to address a growing gap in traditional healthcare. Their mission: provide expert, evidence-based hormone therapy, safe and effective weight loss, and personalized wellness solutions that enhance health and improve quality of life.

Your safety, your results, and your long-term success are always our top priority. We take the time to listen, understand, and guide you with care that’s both individualized and effective. This is wellness done right – board-certified experts focused on what matters most: YOU.

Testosterone replacement therapy (TRT) can be life-changing for men with low testosterone. Low testosterone is common, even in younger men, and it has gotten more common over time. Studies have shown that average testosterone levels have decreased by at least 25% over the past several decades, putting a significant percentage of men at risk for low testosterone. Symptoms of low testosterone include low energy, fatigue, low sex drive, weak or less frequent erections, ED, loss of muscle, weight gain, low metabolism, low motivation, irritable or anxious or depressed mood, and feeling past your prime. Men may attribute these symptoms to normal aging, but they are often due to hormone loss. If you feel symptoms like these are holding you back, schedule a free consult and in-office blood test to see if testosterone replacement might be a good choice for you.

Bioidentical hormone therapy is by far the best treatment we have for symptoms of perimenopause and menopause. Bioidentical hormone therapy addresses the root cause of menopause transition symptoms, which include hot flashes and night sweats, vaginal dryness and atrophy, brain fog, irritability, low libido, difficulty achieving orgasm, joint pain, mood changes, heart palpitations, and migraine headaches. Additionally, bioidentical hormone replacement decreases the risk of chronic disease (heart disease, osteoporosis, dementia), and is the best anti-aging intervention we have.

MDTW provides a comprehensive weight loss program that combines GLP-1 medication with professional oversight and personalized support and guidance. Our board-certified providers, Dr. Oliak and PA Mollet, have specialized in weight loss for >20 years, and have helped 1000s of patients achieve lasting weight loss success. Quality care makes all the difference!

No, MD Total Wellness does not accept insurance. We accept all major credit/debit cards as well as payments from HSA or FSA accounts. Our affordable, pay-as-you-go monthly pricing includes personalized care with board-certified clinicians, medication, and in-office blood testing.

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.

I visited MD Total Wellness for the first time yesterday afternoon, and I couldn’t be more impressed. I live nearby and have passed their building many times, but never realized they offered peptide therapies. After researching beauty peptides, specifically GHK Cu, I knew I didn’t feel comfortable purchasing from an unknown online source.

From the moment I walked in, the experience was exceptional. The facility is beautiful and welcoming, and the service was truly top-notch from the front desk team, to the intake nurse, to the physician. Dr. Oliak took time to thoroughly discuss my treatment plan, dosage, follow-up schedule, and sourcing standards, which immediately put me at ease and reinforced my confidence in moving forward.

I am genuinely happy to have found MD Total Wellness and look forward to continuing my care here. Highly recommend.

Everyone here is so sweet! As soon as you walk in, you are greeted by Casie’s bright smile and a cozy seating area! My visit was for weight loss, and Allie was very thorough in explaining all of my options and what would be best for my lifestyle! As someone who has numerous doctor’s appointments, it was very refreshing to have someone who is not only personable, but also genuinely cares about my history and goals. I highly recommend this sweet group if they have what you are looking for! Thank you MD Total Wellness!
