Discover Your Path to Wellness

Thorough Intake Process

Before we meet, I ask you to fill out a very detailed intake form that includes questions about your health history, environmental exposures, and specific concerns. This allows me to get a comprehensive view of your well-being and tailor my approach to your unique needs.

Based on your situation and budget, we'll decide on the necessary functional lab testing. From our visits, you will receive a superbill that you can submit to your insurance.

Comprehensive Testing and Treatment

Once I've assessed your situation, I design a specific testing regimen, supplement program, diet plan, and exercise routine tailored to you. I'll provide you with a detailed email with links and resources, so you have everything you need to understand and follow your personalized plan.

Your health journey doesn't end there. We'll stay in touch through emails, texts, or calls to ensure you're progressing well. Your follow-up appointments will be scheduled around your testing and treatment plan.

Open Line of Communication

You may have noticed in conventional medicine, the relationship between a patient and their doctor is often fleeting. Perhaps you've experienced those hurried appointments, rushed through in a matter of minutes. I understand how that makes people uncomfortable, even unwilling to fully share their concerns and goals.

That's why I'm passionate about creating a partnership with my patients. With me, you will never feel rushed or just another name on a list. I'm committed to a relationship where we openly discuss your health, your concerns, and your well-being.

Accountability and Coaching

Unlike larger functional medicine practices, I run a one-man show. I personally read your emails, order your labs, and provide you with undivided attention and care.

I also act as a health coach, providing you with accountability – something often missing in healthcare. I use wearables like glucometers, Whoop, Oura, and Apple Health to keep track of your progress and even share my workouts with you. My approach is detailed, personalized, and focused on your optimal health.

Strive for Optimal Health

Whether you're here for weight loss, hormone optimization, reducing the risk of Alzheimer's, or just general well-being, I approach your care holistically. I look for risk factors that others might overlook, utilizing tools and tests that are specific to your concerns, and even offering cutting-edge screening methods for those focused on cancer prevention or cardiovascular health.

About Me

My approach to healthcare is holistic, acknowledging the intricate interplay between systems within the human body and how the modern lifestyle can cause imbalances. I've developed expertise in managing a wide array of conditions - from chronic fatigue syndrome to gut issues, anxiety, autoimmune conditions, to hormone and metabolic issues.

My professional journey led me to the University of North Texas Health Science Center for my medical degree and then Samaritan Family Medicine Residency Program in Corvallis, Oregon. I'm certified by the Institute for Functional Medicine and am also board-certified by the American Board of Family Medicine.
