Who We Are
Walnut Street Center is able to offer the services it does thanks to all of our amazing employees!
Each is an important part of the organization and works tirelessly year after year. The relatively small Senior Management team has a combined 100+ years of experience in the human services field, and have all worked to improve and build upon Walnut Street Center’s programs and offerings during their time with the organization. With the ability to have a completely hands-on and personalized approach (due to having a small team), they each bring their passion, as well as their skill, to the management of Walnut Street Center.
