Hilary Marshall

President T-Bones: 2009-2012

Bio:

After 24 years in healthcare, I still don’t know what I want to be when I grow up. I majored in Long Term Healthcare Administration at Texas State University. My heart was 100% into being a Nursing Home administrator. 10 years later, I decided to put my operations experience to use elsewhere, and was convinced by a friend to try out Practice Administration. She happened to work in Orthopedics, so that’s where I landed. I made some amazing friends and learned so much, including my time organizing the TBONES meetings. I tried emphatically to fill Michael Berkowitz’s shoes, and took on the President role the best way I knew how. I realized I thoroughly enjoyed arranging speakers, lining up vendors and most of all, organizing the social events.

After leaving Orthopedics, and a seemingly eternal stint at the largest OB/GYN group in Austin, I spent about a year doing contract work for an independent physician and Whole Foods Wellness Program. My time with the Whole Foods group was a learning experience in setting up a self-funded insurance plan and developing a wellness center onsite for employees.

I currently work for Ascension Medical Group, specializing in workflows for providers and their staff, revolving around EMR and accompanying software used in the offices and ancillary services. I have been with Ascension for over two years, and am enjoying the consulting aspect that my current position has, in contrast to the operations role.

Time has flown by with my family in Round Rock, as my older son just graduated from Round Rock High School and is working full time while he figures out his next steps. My younger son is a sophomore, and keeps us very busy between football and Lacrosse.
