Nick Holwey, PA-C · Emergency medicine
My name is Nick Holwey, and I am an Emergency Medicine Physician Associate with more than 13 years of clinical experience and the founder of Theosis Medical. I earned my Master of Physician Assistant Studies from Wichita State University after completing my undergraduate degree in Food Science and Human Nutrition at the University of Illinois.
Emergency medicine has been the foundation of my career, with experience spanning Level I trauma centers and high-acuity emergency care to community and rural emergency departments, as well as urgent care, telemedicine, hospital medicine, and prehospital emergency care. I am NCCPA-certified, hold the Certificate of Added Qualifications in Emergency Medicine (CAQ-EM), and maintain licensure across multiple states.
Today, I practice primarily as an independent contractor in emergency medicine through Theosis Medical, providing care in rural and community emergency departments where adaptability, sound clinical judgment, and the ability to work effectively with limited resources are especially important.
Beyond emergency medicine, I have maintained a longstanding interest in lifestyle medicine, nutritional biochemistry, and exercise physiology. My degree in nutrition has continued to influence the way I think about health and disease, and I regularly follow the evolving literature in these areas with a particular interest in how evidence-based nutrition, exercise, and lifestyle interventions can both improve but also prevent long-term health problems and disease. I incorporate these principles into my practice when possible, but time is typically limited in emergency medicine, and so my hope is to eventually develop a more dedicated space within Theosis Medical to help patients translate that evidence into practical, sustainable changes that fit real life.
While my experience and training shape me as a clinician, my faith and family shape who I am as a person. As a husband and father, I’m continually reminded that every patient is someone’s loved one. My faith likewise calls me toward service, humility, compassion, and continual growth—principles that influence both the way I practice medicine and the kind of company I want Theosis Medical to be.
After more than a decade in emergency medicine, my approach remains straightforward: practice excellent medicine, be dependable when people need you, and treat every patient with the dignity and compassion I would want shown to my own family.
When I was choosing a name for my independent practice, I wanted something that meant more to me than a business name. I wanted a daily reminder of what matters most in life, rooted in my faith as an Eastern Orthodox Christian.
Orthodoxy has a striking overlap with medicine. The Church has long described sin not primarily as a list of broken rules, but as a spiritual illness. It calls the Church a hospital for the soul and Christ the Great Physician. In that view, every one of us is in need of healing, and all of us are somewhere along that road.
Theosis is the word for where that path leads: the lifelong process of being healed and transformed, growing through humility, compassion, and love into who we were created to be.
I chose the name to keep me grounded in both kinds of healing. Physical and spiritual health are never fully separate, and when someone comes to me for care, I try to keep that in mind. I'm still on that journey myself, and I'm caring for people who, whether they see it this way or not, are on it with me.
My patients don't need to share my faith, and I'll never ask them to. Everyone receives the same care, attention, and respect, whatever they believe. The name is a standard I hold myself to: to practice sound medicine, to treat each patient the way I'd want my own family treated, and to keep growing as both a clinician and a person.
As an independent contractor, Theosis Medical lets me bring that approach wherever I'm needed, providing experienced, dependable coverage to hospitals and communities across the Midwest. Wherever I'm working, I strive to provide high-quality, evidence-based care, practicing in humility and aiming to be a little better than I was the shift before. Theosis remains the focus, and I'm grateful for the opportunity to serve, striving to help with healing in more ways than one.

Future plans
Although Emergency Medicine is the bread and butter of Theosis Medical, my long-term vision extends beyond treating illness when it happens. I want to help people prevent the conditions that land them in the emergency department years later. My passion is to help people become healthier, stronger, and more resilient but in a way that fits their life.
With a background in Food Science and Human Nutrition in addition to more than 13 years of clinical experience, my goal is to develop a practical approach to lifestyle medicine that cuts through the noise. The world of nutrition and exercise has been overcomplicated by Men's Health and lifestyle magazines making it impossible to know what is truly beneficial.
Life is busy. Diets are difficult to sustain. Exercise can be time-consuming and expensive. And most people don't need another complicated program telling them to change everything at once.
Instead, I want to focus on the minimum effective dose: identifying the small number of evidence-based changes that can produce the greatest impact. Think of it as the 80/20 approach to better health—focus on the 20% that delivers 80% of the results.
Through individualized consultations and targeted laboratory testing, the goal will be to understand where you are today and build a realistic plan around your health, your goals, and your life. The approach is one I've applied in my own life: make the right things easier to do, eliminate unnecessary complexity, and focus effort where it matters most.
Alongside preventive and lifestyle-focused care, I also plan to expand Theosis Medical to provide telemedicine for appropriate acute and urgent-care concerns—giving patients a convenient option when something needs attention without necessarily requiring a trip to an urgent care or emergency department.
01
Evidence-based lifestyle consultations drawing on my background in nutrition and medicine, with practical strategies designed to help you get leaner, get stronger, improve your health, and build habits you can actually maintain.
Open the hacks02
Targeted laboratory testing to better understand your current health, followed by an individualized, easy-to-follow plan. No unnecessary complexity—just actionable priorities built around the minimum effective dose and the changes most likely to move the needle.
03
Convenient virtual evaluation for appropriate acute medical concerns—the sore throat, rash, minor illness, or other problem that needs medical attention but may not need an emergency department.
Theosis Medical is still growing, and I want its future services to solve real problems for real people.
Is there a service you'd find useful? Something about healthcare, nutrition, fitness, or accessing medical care that feels unnecessarily difficult?
I'd like to hear it.
