Nova means new beginnings
It represents renewed clarity and transformation—for our patients and for us. After years practicing medicine on separate paths, we’ve come together as husband and wife to co-found a practice that reflects our shared purpose. This is the first time we’ve aligned our expertise around one unified mission. Nova is not just what we do it’s who we are.
Live Well.

What are your Blind Spots?

Two Powerful Paths.
One Personalized Journey
These pillars guide every personalized plan we create—helping you prevent disease, restore balance, and unlock your body’s full potential.
Health optimization
Your body is designed to thrive, not just survive.
Metabolic & Performance Optimization
Hormone & Aging Support
Early Detection & Risk Assessment
Resilience & Lifestyle Enhancement
Poor metabolic health is at the root of many chronic diseases, including diabetes, heart disease, cognitive decline, and accelerated aging. By optimizing your metabolism and body composition, you build a powerful foundation for disease prevention, sustained energy, and lifelong strength. This is about protecting your future and empowering you to stay active, sharp, and engaged. It means looking and feeling your best now, reaching your fitness goals, performing at a high level in your career, and traveling and staying active well into your later years.

- Bone Health (Echolight)
- Body composition analysis (DEXA, InBody)

- Mitochondrial rejuvenation (including NAD+)
- Peptides, IV therapy, and targeted supplements
Hormones are the body’s master regulators, influencing everything from energy and metabolism to mood, sleep, and longevity. As we age, hormonal shifts can disrupt these systems and accelerate the aging process. Many women notice stubborn weight gain, hot flashes, night sweats, brain fog, and low libido during perimenopause and menopause. Men may experience declining strength, reduced motivation, poor recovery, and decreased vitality as testosterone levels fall.
- Male and female hormone optimization (perimenopause, menopause, andropause)
- Adrenal function assessment

Chronic Illness Root Causes & Rebuilding
You may be struggling with unresolved symptoms or a diagnosis that conventional care has not fully explained or truly helped. Too often, traditional medicine focuses on giving you a label but stops short of asking why your body is out of balance or what is truly driving your symptoms.
You might find yourself taking multiple prescriptions, such as antidepressants, acid blockers, high blood pressure medications, or immunomodulators, that mask symptoms without addressing the actual cause. Over time, these medications can lead to new side effects, deeper imbalances, or the feeling of being stuck in a cycle with no true resolution.
- Autoimmune conditions and chronic inflammation
- Mold exposure illness
- Hormone dysfunction, fatigue, brain fog
- Long COVID
- Gut–immune–brain axis healing
- Alternatives to lifelong pharmaceutical dependency
- Trauma and nervous system dysregulation
- Sexual health concerns: erectile dysfunction, low libido
- Cardiovascular disease – CAD, CHF, arrhythmias
- Cognitive impairment
- Neuroplasticity after CVA, TBI
- Mental health
Where the two Worlds meet
We use precision diagnostics, compassionate care, and integrative therapies to meet you where you are—whether you’re optimizing or recovering. No two plans are the same. Our tools include genomics, advanced imaging, personalized nutrition, IV therapy, peptides, hormone therapy, and mind-body medicine.
Nova is different from high-tech longevity clinics. While we share their commitment to innovation, we add the depth of whole-person care, personalized physician engagement, and integrative healing. Here, we don’t just focus on performance we address the roots. You’re not just a data point. You’re a whole person with a story we’re here to understand.
"Whether you're here to stay well or get well, we're here to listen, to guide, and to co-create your next chapter in health."
