    The doctor who assisted me was very good and explained in detail the procedures to be followed

    He answered all my questions and addressed my concerns about the situation.

  • May 4, 2024

    I got very good help from the doctor. The nurse found prior lab results from year 2021, and the doctor referred to prior diagnosis and results. It was impressive, and caring.
