Nick Holwey, PA-C · Emergency medicine
My name is Nick Holwey, and I am an Emergency Medicine Physician Assistant 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.
I believe that healing extends beyond treating symptoms — it involves recognizing the full dignity of every person who walks through the door. At Theosis Medical, this conviction shapes how I approach every patient encounter.
The name Theosis draws from an ancient Eastern Orthodox Christian concept describing the lifelong process of personal growth and transformation — our humanity working in perfect cooperation with divine grace to become more fully who we were created to be. This comes through humility, compassion, wisdom, and service to others. At its heart, it reflects the idea of participating in something greater than ourselves: a continual journey toward perfection, integrity, and deeper connection with those around us, and ultimately God.
While this understanding is rooted in my faith, it is not something I expect of my patients. People come from many different backgrounds, beliefs, and life experiences, and that diversity is respected here. The principles behind the name are standards I set for myself as a clinician — not requirements for those I serve. Every individual who entrusts me with their care will receive the same high-quality treatment, compassion, and respect, regardless of background.
In the fast-paced world of emergency and hospital medicine, I often meet people on some of their hardest days — amid pain, fear, uncertainty, or loss. I strive to meet those moments with patience, attentiveness, and genuine human connection. I view each patient not merely as a diagnosis or a chart, but as a person of inherent worth deserving of clear communication, thoughtful care, and dignity.
As an independent contractor, Theosis Medical allows me to go where the need is greatest, providing experienced coverage to hospitals and communities across Wisconsin and Illinois. I approach this work as both a professional responsibility and a personal calling: to deliver excellent medicine while continuing to grow as a more compassionate, reliable, and effective clinician.
My goal is simple: that every patient leaves my care not only with better health, but also with the quiet assurance that they were truly seen, heard, and treated with kindness.

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.
