Dr Hassett is a rare breed. He truly cares for his patients. He clearly reviewed my files before meeting with me as a new patient. He accepted me as a senior with a complicated medical history and a short timeline until an important upcoming surgery. I received multiple calls from his staff as issues arose with bloodwork flagging the need for follow up before my upcoming surgery. Having him on my team has removed so much stress for me that I will be going into my surgery with confidence and no fear.
