Built by people who believe
better health changes everything
Zvia Weight Loss & MedSpa brings together clinical expertise and proven business leadership — united by a single purpose: helping you show up better at home, at work, and in your community.
From building technology
to building healthier lives
Zvia started with a frustration: too many weight loss clinics promise the world and deliver a prescription. No real listening. No real plan. No one genuinely invested in whether it works.
We built something different — a practice where the clinical rigor is real (every protocol is medically supervised, every plan is personalized to your biology) but so is the human connection. The team here actually gets to know you. They care how it turns out.
That combination — precision medicine delivered by people who genuinely invest in you — is what makes Zvia work. It's why clients stay. And it's why the results last.
This is what you'll feel here
We care enough to dig deeper
We run 70+ marker panels because guessing isn't good enough. We use 3D body composition scanning because the scale lies. The clinical depth isn't cold — it's how we show we're paying attention.
You're never just a number
Your provider designs your protocol. Your care team knows your name, your story, and what you're working toward. From your first visit through every follow-up, you're working with people who are genuinely in your corner.
We play the long game
Quick fixes don't work — and we won't pretend they do. Every protocol includes a graduation pathway so your results hold after active treatment ends. We'd rather you not need us forever than keep you dependent.
The humans behind the protocols
If you read our reviews, you'll notice a pattern: people connect with the team first. The clinical expertise earns their trust. But it's the genuine care that keeps them coming back.
Tom Higgins
Founder
A Denver native and lifelong builder, Tom founded Zvia after a career spent constructing systems that scale — and a personal conviction that better health changes how people show up in every part of their lives.
Tom's entrepreneurial path began early. He put himself through the University of Wyoming, earning a B.S. in Computer Science, and later completed an Executive MBA at the University of Denver. Between those degrees, he earned a Series 7 investment broker license and co-founded a mortgage banking company — all before age 25.
His largest venture, New Dawn Technologies, grew from a solo project into a 120-person government software company serving states, counties, and tribal nations across the U.S. and internationally. New Dawn was named to the Inc. 500 list of fastest-growing companies four separate times and was voted one of the best companies to work for in Utah. Tom ultimately sold the company to Journal Technologies, a portfolio company of Berkshire Hathaway vice chairman Charlie Munger.
At Zvia, Tom brings that same intensity to healthcare — combining operational strategy with deep personal knowledge of peptide therapy, hormone optimization, and metabolic science. He is not a passive business-side owner; his understanding of the clinical landscape rivals that of many practitioners, and he is actively engaged in protocol research and development alongside the clinical team.
When he's not building Zvia, Tom is an avid photographer whose work has taken him from Machu Picchu to the Amazon basin to Alaska's Denali wilderness. He lives near City Park in Denver with his wife Cathy and their two dogs, Finn and Elwood.
Sharon Blumenthal, FNP-C
Clinical Director
Sharon serves as Zvia's Clinical Director and the clinical authority behind every protocol the practice offers. A board-certified Nurse Practitioner with deep expertise in weight management, peptide therapy, hormone optimization, and medical aesthetics, she is the creator and final medical voice behind every treatment plan — and the person patients describe as their cheerleader every single week.
For Sharon, weight loss is never just about the number on the scale. She reframes every patient's journey around overall health and vitality — connecting metabolic function, hormone balance, and nutrition to outcomes that patients can see and feel. She brings a detective's rigor to clinical care, moving beyond "normal" lab results to prioritize what patients are actually experiencing, using bloodwork as a guide rather than a rulebook.
Nothing reaches a patient at Zvia without earning its place. Sharon personally vets every protocol, product, and piece of technology through extensive research — if it's offered at Zvia, it's backed by data. That same standard extends to aesthetics, where she treats the skin as an extension of internal health, connecting hormonal and metabolic optimization to lasting external results.
Her approach is defined by partnership, not prescription. Sharon meets patients where they are — whether that means a structured fitness regimen or a walk in the park — and walks alongside them with weekly supervision, encouragement, and real-time protocol adjustments. She knows that walking through the door for the first time is the hardest part, and she builds an environment that honors that courage: warm, non-judgmental, and focused entirely on the individual.
With a personal background in CrossFit and yoga, Sharon brings firsthand understanding of what it means to push your body toward a goal — and the empathy to know that everyone's path looks different.
