About
Healthcare deserved more.
Chosen Health was built for people who want answers, optimization, and a trusted provider relationship — not symptom management.
Our Mission
To help people understand their body, act on the right data, and build a sustainable plan with a trusted care team.
The Problem We Saw
Patients leave conventional appointments with prescriptions and confusion. Online lab companies hand over data without context. Telehealth ships medication without surrounding it with real care. None of it builds the relationship people deserve.
Our Model
Chosen Health combines the data of a biomarker platform, the personalization of functional medicine, the convenience of shipped products, and the trust of a local provider-led team. Local in New York and New Jersey. Virtual where appropriate.

Our Vision
A generation that treats their biology as their most important asset — and has a care team to match.
Leadership
Jacob Katz, MD, FAAFP
Founder & Medical Director
The Shift
Most medicine waits for something to break. Dr. Jacob Katz spent his career fixing what breaks. Now he is focused on what comes before.
For more than a decade, Dr. Katz has worked the places where the body meets its limits. Ringside at professional boxing and MMA bouts. On the sidelines of college and professional teams. In the exam room with patients of every age and ability level. He kept seeing the same pattern. By the time most people reach a doctor, the damage is already done.
Conventional care is built to react. It waits for a diagnosis, then treats it. Dr. Katz wanted to work upstream. He founded Chosen Health to practice medicine the way it should work. Proactive. Personalized. Aimed at the root cause.
“I spent years putting people back together after they broke. I would rather keep them from breaking in the first place.”
The Approach
This is the Medicine 3.0 model. Older medicine guessed. Modern medicine reacts to disease after it shows up. Medicine 3.0 gets ahead of it. The goal is not only a longer life. It is a longer healthspan, the years you spend strong, sharp, and doing what you love.
Dr. Katz reads the whole system. Bloodwork, biomarkers, movement, sleep, nutrition, stress. He looks for the cause under the symptom instead of quieting the symptom and moving on. Then he builds a plan around the person in front of him, not a billing code.
He also believes patients get better when they own their care. So he teaches. He breaks down complex biology into plain language with diagrams and clear explanations. You leave understanding your own body.
