How it all Started

A mother’s legacy for two local physicians. Nedra Downing, DO, a well-known Clarkston-area physician, who will retired and her daughter, Laura Kovalcik, DO, who will continue running the practice.

This mother-daughter story is unique. Dr.
Downing and her two daughters are all physicians
and all graduated from MSU’s College
of Osteopathic Medicine, which was a
first for this college. One daughter, Margaret
Tirkes, DO is a Board-Certified Radiologist
in Dallas, and Laura Kovalcik, DO is a
Board-Certified Internist. A highlight of Dr.
Downing’s life was seeing both her daughters
graduate from her Alma Mater.
