I was seen right away. Dr Guider thoroughly explained what might be happening with my issue. I booked a time for a procedure which happened within a reasonable timeline. The nurses during the procedure were thorough. The procedure was quick with Dr Guider explaining what she found. I was pleased. Everything went according to plan.

Procedure started a little late, but as usual Dr Lily was wonderful. Everything went great, no polyps. My trust in Dr Lily is undeniable.. Thank you
