“I knew this provider would be exceptional as she Is passionate about her specialty. She is also a runner and understood my concerns which were dismissed by prior gastroenterologists as too minor to treat. She was very empathetic when my condition made me cry. Dr Tsounian (sorry, spelling) is an exceptional and competent provider and I feel safe in her care. The office staff gave me detailed instructions in a folder which I appreciated. My home address was considered when scheduling follow up appointments which was very thoughtful.”
