About Us

Our Approach To Helping Patients is Far Different From What you may be used to...


Dr. Casey Tramp, MD

Family Medicine, Functional Medicine, and Menopause Specialist

Casey Tramp, MD is a certified functional medicine and family medicine doctor who is passionate about helping families and individuals in a supportive environment. 

She became passionate about helping people find the root cause of their problems after spending many years in traditional medicine, where she became disillusioned with not having enough time or tools to really partner with patients to improve their health.

Casey became convinced of how well functional medicine works as she saw more and more patient’s lives transformed. She is dedicated to spreading the word that there is a way to restore balance in the bodies and lives of her patients—which will allow them to heal.

Dr. Tramp has been a practicing family medicine doctor since she graduated from the University of Kansas Medical Center in 1999.  She finished her family medicine residency at Baptist Medical Center in KC, MO and followed that with a fellowship in obstetrics at Truman Lakewood in KC, MO.

“A medical doctor who sees 30 patients a day certainly cares for every patient. But it’s awfully hard to hear much of what patients have to say in a 10-minute visit.” –Dr. Casey Tramp

Dr. Tramp also has a life long interest in integrative medicine.  She began studying integrative medicine during medical school and has continued through-out her career. 

Since 2011 she has been practicing and learning functional medicine through the Institute of Functional Medicine and has recently finished certification.  

She has also completed Andrew Weil’s 200-hour Integrative Fellowship for faculty physicians.Casey strongly believes that health is within each person’s reach and isn’t dependent on people taking another pill. 

She has a husband and 2 boys who are pretty passionate about health too! One of her favorite memories is of her first son coming home from kindergarten and asking why they were trying to poison him at school with “all those artificial foods”.
