Betsy Mathies - Senior Manager, Community Engagement

Betsy Mathies.jpg

Betsy Mathies was diagnosed with Parkinson’s Disease in March, 2012. Following a 25-year career in a busy Denver pediatric practice, she suddenly found herself facing new and unforeseen challenges, but also opportunities to help others.

Soon after her diagnosis, Betsy was invited to participate in a clinical trial called PD SELF: Self Efficacy Learning Forum. The focus of the program was to apply the concept of self-efficacy in managing a disease like Parkinson’s and how it could improve one’s quality of life. Not only did the program have a remarkable impact on Betsy, she became an immediate advocate and for the past three years has been co-facilitating one of the Denver chapter’s programs for others who have been recently diagnosed.

She has served on the board of Colorado Neurological Institute for the last several years, most recently as president, where she has led the board through the difficult process of closing the organization in July, 2018.  She also serves as a board member for the Movement Disorder Foundation (MDF) and for the Knoebel Institute for Healthy Aging at the University of Denver.

When not enjoying her grown daughters and their families, Betsy can be found pursuing her passion for golf or enjoying a wine with an ever-expanding circle of friends.  She has been happily married to her husband, Mike, for 39 years.

Betsy has described her Parkinson’s Disease as, “the best thing that’s ever happened to me.” Knowing how enriched her life is with her current capacity to help others, that statement not only makes sense, it defines how purposeful she remains in this next chapter of life.
