Personal Information

I am the first of my family to become a doctor. The melding of science, art and profound human interaction make this the most rewarding calling and career. Being part of the pregnancy journey of a family is always amazing.
My husband and I are raising three spunky children, and love being active with them. We recently added a puppy to the mix, so there is never a boring moment.

Community Involvement

I am active in the Rivkin foundation and its educational arm CanCan - raising money and awareness for Ovarian and Breast Cancer.
To stay involved in my children's activities I serve on the Executive Committee of their Youth Alpine Racing Team (Team Alpental Snoqualmie) in the capacity of Vice President. I am also a USSA certified race official for timing and calculation.
