Meg McElroy is the founder of Center for Collaborative Medicine.

I am passionate about the more holistic and integrative way of practicing medicine.

Evaluation involves so much more than just checking basic labs and giving out pills, and I am here for you to put those puzzle pieces together!” Sara Klopp
