Dr. Lazarus is terrific! When I first saw him six months ago (in person), I had had 10 UTI's in one year and it was exhausting and frustrating. Since my first visit with him in the fall, I have had NONE in six months.

Dr. Lazarus is amazing! Very knowledgeable and respectful. Honestly, most doctors don't listen or prepare for a visit like he did. I worked in Healthcare, so I can tell when someone prepared ahead of time.
