Client Testimonials

“I have now worked with Bill Kerr at High Swartz on two affordable housing transactions, one in Philadelphia and one in Chester, PA. In both instances Bill worked on our land use approvals, zoning and tax abatement issues. I have found Bill to be extremely knowledgeable, organized and thorough in both transactions which saved us a lot of time and money. I absolutely plan on using Bill again as new projects arise and would recommend him to others as well.” – Bruce Morgan President, BCM Affordable Housing, Inc.
