Testimonials | What Our Clients Say

Bernie Flynn

CEO
Mercer Street Friends is the Food Bank responsible for helping those in need in Mercer County. When the pandemic hit, it became abundantly clear that we needed a larger warehouse. We turned to Princeton Property Partners for help in the search for a property that would enable us to appropriately serve Mercer County for years to come. Aubrey Haines educated us about the marketplace, provided us with strategic advice, and sourced many properties for us to consider. He was always available and shared our passion for finding the best property to meet our needs. And they delivered! An extremely hectic and stressful undertaking was made easier by his calm, confident and professional support. Mercer Street Friends Food Bank now is a proud owner of a property that will serve our neighbors well into the future thanks to Princeton Property Partners.
