Dr. Cassidy is tops! He's energetic, upbeat and knows how to help with chronic problems like GERD. He pays close attention to me and all of my questions were answered. Their staff is very friendly and professional. I found the new office, but only because I had simple, very clear directions. I prefer the (existing- they have two) Harleysville office because of my location. If I were in some kind of an emergency I'd go back.
