All the staff members were very kind, friendly and professional. Dr. Fleisher was very detailed and explained everything very thoroughly. I was pretty comfortable and at peace. I had no reason to be nervous or afraid. Everything went well with my procedure. Everyone on the team did a fabulous job during my visit for my procedure. Thank you to Dr. Fleisher and all the staff at Borland Groover. Keep up the great work!
