Joseph G Markoly Foundation Inc

When Joseph Markoly originally established the foundation more than thirty years ago, its focus was on Alzheimer’s and heart disease support, funded through a number of the larger national disease-related organizations. Over time the focus has shifted to helping small to mid-size organizations in our local communities which support children and seniors in a variety of effective ways. 

Markoly Foundation was established in honor of Joseph G. Markoly, an entrepreneur and philanthropist who wanted to make a positive impact in people’s lives.

For that reason, the foundation dedicates a majority of their resources to providing grants to organizations that focus on the treatment of each of these diseases. In addition, Markoly Foundation supports a variety of programs dedicated to helping children and seniors by providing services, supplies, programs and research in areas impacting these demographics.

We are dedicated to providing funding for local nonprofit programs that improve the quality of life for all, but particularly for the children and elders in our community.
