Hear From Evergreen Physician Dr. David Kashmer

If something feels off, your energy, your sleep, the way your body is changing, you're not imagining it. And in most cases, there's a real measurable reason. It's often just one that nobody's looked for yet.
I'm Dr. David Kashmer. I'm board certified in anti-aging and regenerative medicine, and I'm also a board certified surgeon.
We built this one-minute assessment to help you figure out where to focus first--whether that's hormones, metabolism, recovery, or longevity. It's the same triage we'd run if you walked into our office for assessment tomorrow.
So I urge you today to take that one-minute assessment, and at the end, you'll get a personalized read on what's most likely driving how you feel and what to do about it.

Many High-Performing Adults Experience Physiologic Decline Years Before Traditional Medicine Identifies a Problem
-
Reduced recovery, fatigue, poor sleep, hormonal changes, metabolic resistance, and declining resilience are often dismissed as “normal aging.”
-
In many cases, these symptoms may reflect underlying biologic performance decline.

This physician-guided evaluation helps identify whether your body may be underperforming relative to your age and lifestyle demands.
High Performers Often Normalize Symptoms They Shouldn't
Common early signs of biologic performance decline

Persistent Fatigue & Reduced Recovery
I thought it was normal to just be tired all the time. Now, I've worked with Evergreen for over a year, and have been incredibly happy with the results & the interaction with the staff. I've never had more energy or felt better.

Poor Sleep & Non-Restorative Recovery
The Evergreen team is so personable & knowledgeable. They never make me feel rushed and you can tell that they care about people. I'd told myself not sleeping was just my new normal--now, I sleep all night and wake up refreshed!

Hormonal Performance Changes
My work requires me to look and perform my best. Issues with my hair, nails, and energy levels were things I just accepted and struggled to deal with. Evergreen helped me get back on track to feeling and performing my best.

Weight Resistance & Reduced Vitality
I had convinced myself that the weight gain, low energy, and declining libido were just part of getting older. With Evergreen, I feel sharper, more confident, and more engaged both professionally and personally than I have in years.
