About Me

I have been a Physician Assistant since 1999 and joined Mercury Street Medical Group in 2002. For the last 17 years I have been fortunate to have met and been involved with many wonderful people from Butte and the surrounding area. I work primarily under Dr. John Pullman’s supervision and could not ask for a more supportive work environment.

When not working, I love to hang out with my 2 wonderful kids and husband; hiking, gardening and skiing. Butte was not my first home, but I feel blessed to call it home now and for the future.
