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.

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”.

Throughout her nursing career René has focused on helping people achieve optimal health to avoid illness and injury. Years of working with sick patients in the hospital convinced her of the importance of a healthy lifestyle to avoid chronic disease. She enjoys educating people about the benefits of good nutrition and physical activity and equipping them for success in establishing new habits.

 René has extensive experience in traditional medicine but has always fostered her passion for alternative methods of achieving good health. Most recently she has been studying functional medicine through the Institute of Functional Medicine. She has a doctorate degree in advance practice nursing and a master’s degree in nutrition and dietetics, both from KU Medical Center. She also has a bachelor’s degree in nursing from William Jewell College. She has worked as a  primary care provider at the VA hospital in West Haven, CT, and an urgent care provider at KU Health System.

 When she’s not working, René is spending time with family and friends. She is married with 3 adult children and 5 grandchildren. She also enjoys walking or jogging with her dog and going to the gym. Music is a big part of Rene’s mental and spiritual health. She has played the violin for several years and has a lot of fun playing with several musical groups. She is a member of the Lee’s Summit Symphony and is in a fiddle club. 

Heather has a Masters Degree in Human Nutrition & Functional Medicine and has worked in the fitness industry as a Certified Personal Trainer, Health Coach and class instructor for over a decade. 

She loves to encourage and educate others to create healthy lifelong changes and believes that there is no one way of healthy eating, exercising and living that works for everyone as we are all on a different health journey. 

She loves being part of the process to help others find what works best for them to find healing and create sustainable healthy lifestyle behaviors. In her free time she enjoys spending time with friends and family, working out, trying new recipes and soaking up sunshine.
