I’m Dr. Jessica Knape, the Founder of HealthSpan Internal Medicine. I’m a double board-certified physician in Internal Medicine and Integrative & Holistic Medicine with more than 20 years of experience caring for adults across the full spectrum of health — from hospital and clinic to assisted living, memory care, and home-based medicine.
Throughout my career, I’ve witnessed thousands of healing journeys. I’ve helped patients recover from serious illness, reverse chronic disease, and reclaim their vitality. I’ve also had the privilege of walking beside many at the end of life — experiences that have shaped my belief that medicine should not only extend lifespan but healthspan: the years of life lived in strength, clarity, and joy.
That philosophy is the foundation of HealthSpan Internal Medicine, my Boulder-based medical practice dedicated to precision, prevention, and personalized care. My mission is to help each patient thrive — physically, cognitively, and emotionally — through a thoughtful integration of internal medicine, functional medicine, genomics, and lifestyle optimization.
After decades caring for patients and loved ones with dementia and cognitive decline, I became deeply committed to helping others protect and restore their brain health. That passion led to the creation of the BrainSpan Program, an advanced framework built on the Bredesen ReCODE 2.0 model.
I live and practice in beautiful Boulder, Colorado, where I share life with my husband Carlos, our three children, and two dogs. I’m a dedicated yoga practitioner, lifelong learner, and seeker of truth — passionate about helping others build lives rich in energy, balance, and meaning.
Let’s talk about how we can expand your HealthSpan and BrainSpan — and help you live not just longer, but better.

Tristam is a Licensed Professional Counselor Candidate (LPCC), and is board certified in electroencephalogram (EEG) neurofeedback through the Biofeedback Certification International Alliance. Since graduating with a master’s degree in mindfulness based mental health counseling in 2017, he has focused his professional interest in the field of neurotherapy which utilizes the use of brain-computer interface (BCI) technology to promote better brain regulation. Tristam specializes in helping his clients find symptom reduction and wellness through a multimodality approach consisting of neurofeedback, microcurrent neuromodulation, and heart rate variability (HRV) training combined with humanistic/relationship focused talk therapy.
Many of the issues that people struggle with such as anxiety, depression, ADD, and OCD have predictable brain signatures that can be mapped out with the use of EEG technology. And this is why Tristam considers EEG technology so compelling as a tool to help move the needle for the presenting problems his clients experience. EEG enables the ability to look “under the hood”, at brain markers directly, to assess brain functioning and corresponding symptom presentation. Furthermore, he utilizes this technology as a tool to guide the brain back in the direction of healthy functioning. The result is a subjective experience of symptom reduction, improved wellness, and greater resilience.
While Tristam brings a lot of professional training and skill to his work, he likes to connect foremost with his clients from a place of shared humanity. He has found that it is a potent combination to have objective brain data and cutting edge BCI technology employed within a genuine and non-judgmental therapeutic context.
