Hormone & Regenerative Medicine Specialist

We sat down with Samiha Rahman, PA-C, to talk about her work as a regenerative medicine provider in Wellington and Palm Beach, her go-to iced vanilla latte with cold foam, and the NAD+ protocol that surprised her with its “secret weapon” impact on energy and metabolism.

Can you tell us a little about yourself? Where do you live and what do you enjoy outside of work?
I’m a physician assistant and Florida native. I attended the University of Florida, go Gators!, and earned my master’s at Nova Southeastern. I currently live in Wellington and feel lucky to bring RegenCen’s approach to wellness to this part of the coast. Outside of work, I’m loving rom-com novels lately, and I wind down most evenings with a yoga class to reset and recharge.

What was your path into regenerative medicine?
During PA school, my rotations in internal and family medicine opened my eyes to how symptom-focused traditional care can be. I kept thinking, "There has to be more we can do." When I met Dr. Lo and learned about RegenCen, it clicked. Our model isn't just about avoiding disease, it's about helping people feel like themselves again and personalizing care to their specific needs.

Have you personally tried any RegenCen services?
Yes! I did medical weight loss with semaglutide in 2023. I initially wanted to lose 10 to 15 pounds, but what I really gained was a healthier mindset. Semaglutide helped me tune in to hunger cues and make more mindful choices. It really supported a lifestyle change, not just a number on the scale.

You’ve helped build RegenCen in multiple markets. What led you to Wellington?
I started in North Naples, then moved to Winter Park, and now I’m here in Wellington. I’m passionate about educating patients and helping them transition from aesthetic-only care into full regenerative support. After getting married, I relocated to live with my husband, and with four brand-new RegenCen offices opening on Florida’s southeast coast, it felt like perfect timing to bring what I love doing to a whole new audience.

What are the most common concerns patients share with you?
Low energy, weight gain, and brain fog are the big ones. Often, patients just say, “I don’t feel like myself anymore.” That can snowball into poor sleep, mood changes, and lack of motivation, which is where we step in to figure out the root cause—hormones, cellular energy, or both.

What’s your advice to someone who feels “off” but doesn’t know where to begin?
Start by talking with a provider and getting lab work done. Whether you’re 35 or 65, we tailor everything to your biology and goals. Sometimes NAD+ or a metabolism booster is enough; other times it’s hormone optimization. We build plans to help you feel better now, and keep feeling better long term.

What results do men typically experience from testosterone therapy?
The biggest improvements are in energy, stamina, cognitive focus, and strength. I see a lot of men in their early 50s who feel burned out, frustrated, and stuck. After just a few weeks on testosterone and sometimes NAD+ as well, they’re more focused, more motivated, and more themselves—mentally and physically.

Can you share a patient story that stuck with you?
One that always stays with me is a woman in her late 60s who struggled with vaginal dryness and incontinence. She was told by other providers that pads and pelvic therapy were her only options. We started her on conservative hormone therapy, one MorpheusV treatment, and a PRF Vaginal Rejuvenation. A few weeks later, she was in tears. She could pick up her grandchild without worry. It was a life-changing moment for her, and for me too.

What treatment surprised you most with its impact?
NAD+. I used to think of it as an “anti-aging buzzword,” but the real-world effects are incredible. My patients report feeling sharper, lighter, and more energized after even one treatment. I do half-dose NAD+ weekly or biweekly myself when I feel my energy dipping, and it works like a charm.

What’s one thing you wish more people knew?
Perimenopause is real and treatable. So many women suffer in silence because they’re still getting periods and think they have to wait for menopause to address symptoms. You don’t. Hormone therapy can make that transition smoother, not miserable.

What drew you to work at RegenCen?
Dr. Lo was a huge part of it. His mentorship made me feel confident, supported, and empowered to do this work at a high level. I also trained closely with Anna Donaghy, our Traverse City provider. Watching how she treated her patients, I remember thinking, “I want to be her.”

And just for fun… What’s your coffee order?
An iced vanilla latte with cold foam and oat milk—basic, but perfect.

If you weren’t in medicine, what would you be doing?
I’d be a teacher. I love mentoring new RegenCen providers and watching them light up when they connect with patients. I think I’d thrive teaching middle school!

What’s a myth about regenerative medicine you love busting?
That it’s only about stem cells or expensive treatments. Regenerative medicine is broad and accessible, it includes everything from hormone therapy to PRF to red light LED. It’s for anyone who wants to feel and function better.
