Bill Kerr's Legal Insights

Client Testimonials

Bruce Morgan President, BCM Affordable Housing, Inc.

"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."

"I contacted High Swartz on a recommendation from another law firm to help with zoning planning board in the Cheltenham Township, PA. I needed a law firm with experience in managing the zoning relief for adding a unit to my apartment. Bill Kerr and Stephen Zaffuto from the firm helped me right from advising on my case to filing the case with the planning and zoning boards. Bill also helped me pick an experienced architect who was familiar with the board and the township building codes. They were very professional and kept me abreast with the agenda on every planning meeting. Stephen prepared the case and also represented my case strongly during the hearing which led to the board granting the zoning relief. I am really happy to have chosen the firm for my case. 5 stars for a job well done!
