Meet Dr. Kristen Alexander

I take great pleasure in getting to know our patients on a personal level and treating each one in a caring, professional manner. I feel our team works hard to give each patient the attention he or she deserves in a comfortable, considerate, and welcoming environment. I was thrilled to join the well-respected practice of Dr. Andrew MacDonald and Dr. Edwin Tyska in 2007. In 2011, I became a partner in the practice.

Outside the Office

I am very proud to be a Buffalo native. I have lived in Western New York my entire life, having grown up in North Tonawanda and Clarence. I love the Buffalo area and can’t imagine living anywhere else.

My husband Joel Harden is a high school physics and chemistry teacher. We have a daughter Emery and a son Elliott who keep us busy. We enjoy outdoor activities and cheering for the Buffalo Sabres.
