What Patients Say

Overall sentiment across review platforms: mixed

  • Birdeye: 3.0 out of 5 stars (4 reviews)

Patients praise

  • Professional, caring, and competent physicians
  • Effective management of complex GI conditions
  • Comprehensive explanations from medical staff
  • Efficient and personable nursing care during procedures

Common complaints

  • Difficulties with administrative follow-up and communication
  • Perceived rudeness or lack of care from non-clinical staff

"Will start by saying Dr. Mahajani is fantastic at his job, along with the infusion room nurses, after that it goes straight down hill. Over the last 3 months I've had various people in the office tell me 4 things, guarantee me them, and none of those things have happened."

Birdeye Review

"Dr. Kavathia, or Dr. K as his co-workers call him and how I think of him these days, is a special person and doctor. His compassion and concern for his patients and staff stand out and drive him."
