Always a pleasure to see Drs. Cassidy and Tasan. They answer all questions and are very helpful with information about my daughter's care.

September 22, 2017

After 3 years of looking for an answer for my daughter, we left with tons of information and an actual diagnosis. We are very appreciative of Dr. Cassidy, she made us feel not crazy as many other doctors have prior to us visiting her. She was very informative and actually gave us paperwork on my daughter's issue so we could better understand. She answered all of our questions and concerns, she talked to my daughter at her age level, my daughter actually talked to her which is a huge plus with us as she rarely tells new doctors her pain issue, my daughter was that comfortable with her which made things alot easier for us, and Dr. Cassidy was simply amazing. I cannot seem to say enough good things about her... thank you Dr. Cassidy for finally giving us the answer to my daughter's pain issue... it's been a long hard 3 years.

Dr Cassidy is the best Dr around, she sends personal message on test results and overall information needed.

The nurse/assistant was quiet and didn't say much. Dr. Cassidy spent a lot of time with us and really listened to my son's history.
