Practice Manager

I joined OSSO in 2000 and shortly after that became a member of Dr. Unsell’s team. You can say I am a jack of all trades and at some point in time have either learned or have worked in most departments. I am Dr. Unsell’s Medical Assistant and cast tech. I also do his medical records as well as ording and scheduling Botox / Latisse. I am married to a wonderful man who is also a great dad. We have three beautiful amazing daughters that I could not be more proud of. Family and my Faith are a very important part of my life and I have been fortunate enough that I work with doctor and group of people who feel the same. I am truly blessed to have them all in my life.

She started out as a nurse working in the trauma ICU at a major trauma center where she learned to work under pressure in life and death situations.

Additional work settings include surgery, recovery room and pre-op holding. Nursing however is only one of her many passions. Along with being a mom of 4 and managing a household she manages to find time to pursue her love of painting and can boast a history of sold out art shows.
