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 because of the size of the team and the center, they each bring their passion, as well as their skill, to the management of Walnut Street Center.

“Care and Quality are internal and external aspects of the same thing. A person who sees Quality and feels it as he works is a person who cares. A person who cares about what he sees and does is a person who’s bound to have some characteristic of quality.”
