Understand what is shaping your health. Build the capacity to live and perform better.
I am John Paruch, MD, a physician trained in Combined Internal Medicine–Psychiatry and board-certified in Lifestyle Medicine.
That combination shapes the way I practice medicine.
I don't see physical health, mental health, lifestyle, performance, relationships, and environment as separate issues. They are parts of the same human system—and they constantly influence one another.
When we work together, my goal is not simply to identify a diagnosis or prescribe another treatment. I want to understand you: What is working well? What is creating strain? What are we overlooking? Where have you lost capacity? What can be strengthened? And where might a meaningful change have effects across several areas of your life?
A Different Kind of Medical Conversation
Traditional medicine is very good at identifying and treating disease. That remains important.
But sometimes the question is bigger than “What is wrong with me?” You may also be asking: Why don't I feel as well as I think I should? Why am I functioning, but not functioning at my best? Why do I keep improving in one area while struggling in another? What should I actually focus on first? How can I protect my health while still pursuing ambitious goals?
Those are the kinds of questions that interest me.
Rather than looking at one organ system, one symptom, or one diagnosis in isolation, I look for the interactions among the factors shaping your health and performance. That can include medical health, mental health, sleep, exercise and physical capacity, nutrition, recovery, stress physiology, habits, relationships, environment, developmental experiences, identity, purpose, and meaning.
Not every factor needs to be optimized. The goal is to determine which factors actually matter for you.
From Symptoms to Systems
Two people can have the same diagnosis and need very different things. The same is true of two athletes, two executives, or two otherwise healthy people who simply know they are not functioning at their potential. That is why I try to understand the system underneath the symptoms.
The result is not a pursuit of perfection. It is a clearer understanding of where to focus your effort.
Health Is More Than the Absence of Disease
I am interested in the entire continuum of human health:
Sometimes the goal is treating illness. Sometimes it is recovering something that has been lost. And sometimes it is helping an already healthy person become stronger, more resilient, and better able to meet the demands of life. I think medicine should be capable of addressing all three.
I Practice What I Teach
Lifestyle Medicine is not simply something I recommend to patients. It is something I work to live.
I train regularly and consider myself an athlete. I pay attention to strength, conditioning, nutrition, sleep, recovery, mental performance, and the balance between pushing the body and allowing it to adapt.
I don't do these things perfectly—and I don't expect my patients to either. Living this way gives me a perspective that extends beyond textbooks and clinical guidelines. I understand what it means to pursue improvement while having a career, a family, responsibilities, limited time, setbacks, and an actual life.
The goal isn't perfect optimization. It is to identify the things that matter enough to change—and build them into a life you can actually sustain.
A Particular Focus on the Athlete
Athletes occupy a unique intersection between health and performance. They may be extraordinarily fit while struggling psychologically. They may perform exceptionally while sleeping poorly, recovering inadequately, experiencing anxiety, losing confidence, or tying their identity increasingly to results.
Many characteristics that help create successful athletes—discipline, competitiveness, perfectionism, persistence, willingness to tolerate discomfort—can become vulnerabilities when taken too far.
My work with athletes therefore isn't simply about treating psychiatric disorders. It is about protecting and optimizing the person who performs. We can address performance anxiety, confidence, attention, emotional regulation, recovery, sleep, stress, identity, motivation, resilience, relationships, perfectionism, setbacks, injury, transitions, and the psychological demands of competition.
The objective is not to remove every uncomfortable emotion. It is to develop an athlete who can experience pressure, adversity, uncertainty, success, and failure without losing the psychological foundation necessary for sustainable performance.
Peak performance should not require sacrificing the person underneath it.
What You Can Expect From Me
I will listen. I will ask questions that may connect areas of your life that have previously been considered separately. I will take medical and psychiatric symptoms seriously while also looking beyond them. I will help distinguish what is important from what is merely interesting. And when there are twenty things that could be changed, we will work to identify the few that are most likely to matter.
Sometimes that means medication or conventional medical treatment. Sometimes it means sleep, exercise, nutrition, recovery, behavior change, psychotherapy, relationships, environment, or stress management. Often it is a combination.
The objective is not to impose my version of health on you. It is to understand what you want your health to allow you to do—and help you build the capacity to do it.
Who Might Benefit?
- People who want a physician who considers physical and mental health together.
- People with symptoms that don't seem adequately explained by a single diagnosis.
- People doing “all the right things” who still don't feel or perform the way they would like.
- People who want to improve health before disease forces them to.
- People interested in longevity, resilience, or sustainable performance.
- Athletes or high performers trying to improve without sacrificing mental health.
- People who want to understand the factors influencing their health rather than simply receiving another prescription.
- People ready to participate actively in improving their health.
You don't need to be sick to work on your health. And you don't need to be an elite athlete to think seriously about performance. Performance can simply mean having the physical and mental capacity to do what matters to you.
The Goal
I am not interested in promising perfect health, limitless performance, or a life without stress. Human beings don't work that way.
What I can offer is a broader way of looking at your health, the perspective of a physician trained across Combined Internal Medicine–Psychiatry and Lifestyle Medicine, and a deliberate process for identifying what may be limiting you and what may help.
What would become possible if your health better supported the life you want to live?
That is what I want to help you discover.
