Kresser Institute ADAPT Level One trained

In 2010, she moved to Fort Collins, Colorado with her husband and son, because they wanted a lifestyle change and easy access to the mountains.  She worked at another FQHC for 2.5 years with low-income pregnant women, and in 2013, she began working at an integrated medicine clinic.  It was there that she was introduced to the paleo/primal lifestyle and then found her way into the world of functional medicine.  She continued to work there while training with the Kresser Institute for Functional and Evolutionary Medicine in 2016, and she knew that she could never go back to conventional medicine again. 

For the past 3 years, Megan has worked in a functional medicine office called Balanced Well-Being Healthcare.  She has grown as a clinician and honed her skills with functional medicine labs and treatment options.  Helping people address underlying chronic issues and get back to feeling their best is what feeds her soul, and she feels grateful every day for the opportunity to help people identify ways to feel and live their best life.  

Outside of work, she loves spending as much time outdoors as possible with her family and friends – running, hiking, skiing, etc.  She is obsessed with all things related to human nature and healthy habit formation, and she is beyond thrilled to work with the California Center for Functional Medicine.

After stepping away from the workforce to start a family, Gena is happy to resume her career now that her children are both in elementary school. She has a Bachelor’s Degree in Sociology from the Metropolitan State University of Denver and a customer service background of 16 years. Gena lives in Southern California with her husband and 2 boys and has a strong interest in helping others and exceeding client expectations.

Gena also has a personal interest in functional medicine due to an unexpected health diagnosis of her oldest son when he was just two years old. After a lot of research, she was fortunate to find a functional medicine pediatrician in her area. With his guidance, she learned about the gut/brain connection and began the process of healing her son with a special diet that included many supplements and probiotics. She completely changed her family’s lifestyle and began detoxing his body and eliminating all toxins in their food and home environment. Her son has healed significantly in the last 8 years and she could not be more grateful for how far he has come.

Because of this experience she values holistic health and a balanced, healing home with an emphasis on nutrition. She is grateful to be part of an organization that helps others achieve their health goals by addressing the root causes.

Elise is driven to provide exceptional patient care and inspired to help others throughout their personal journey to wellness.
