Facility was convenient, appreciate the Saturday appointment. Staff was friendly and effecient, even though they had a full waiting room. Medical team was knowledgable, explained everything well and were friendly and discreet. Dr. Guirl was prompt, made sure I understood procedure, great beside manner. After procedure, immediately explained any findings and I was on my way. Would definately recommend Dr. Guirl, his medical team and this facility.
