"Exceptional Doctors and Staff. Thes Doctors perform at a level above the rest."
"This office is tremendous! Dr. Sheehan was a kind and patient doctor who spent a lot of time with me figuring out my case. I was and am grateful for his care. Additionally, I am not only grateful but so amazed at his office staff, most specifically, Linda. Linda is a life saver! She fought HARD for almost a year to get my claim paid by my insurance company who gave her pushback over and over. She never gave up! She doesn’t even know me, yet she refused to give up until they did what was right. Linda is such a good person who takes good care of their company’s patients. She is knowledgeable and kind and i’m beyond grateful!"
"Dr. Singh is a great doctor who assisted my 4 year old with her allergies. Listens and is ready to help child alleviate symptoms. Trustworthy and caring."
"Dr Sheehan is an excellent doctor who really cares about his patients. The nurses that work in his office are wonderful and so is the office staff. Dr Sheehan is kind, intelligent, and takes time to make sure his patients are well taken care of. I would recommend this office in the highest possible terms. I go every week for allergy shots, and I think this is a great office. You won’t find another doctor like Dr Sheehan. He is compassionate, and he takes the time to know his patients. He cares deeply about being a great Dr, and he’s a wonderful man too. I don’t know where I would be without him. I have severe allergies, and he has tried so hard to help me. God bless him!"
"I have asthma and an immune deficiency. This could have meant my life was a series of infections and doctors appts..I like to think of myself as athletic and a healthy person. Dr Sheehan diagnosed and treated my asthma and help ease any chronic inflammation. I am so grateful to be swimming and living life without this burden any more."
