They say they are "overbooked" and that means people like myself have to wait wait wait....They are booked until 2022 and I will not wait any longer.

Wonderful staff who are caring and want the best for their patients. My experience with receiving treatment here so far has been beyond what I expected. I really like that they offer multiple services such as both behavioral health and general health.

We have received only the best care at Advantage Care. Dr. Mulqueen is the best primary care doctor ever, she is kind, patient, and follows through. She explains everything in full detail. The dental care is also very good. Five stars!

Please hire welcoming, friendly, and patient secretaries. Please hire nurse-practitioners that won't forget to send the refill requests of medications for this VULNERABLE POPULATION. Thank you.

I just came from there. The facility was clean. Dr. Jaffe answered all my questions. She gave me extra time because a patient canceled. If there was pain, she would stop. Its pretty secluded up there, but its worth it. Theyre also in Freeport so you can always go there, too. But overall, a great experience.

Just received a discharge letter from this clinic claiming my son missed many appointments and has not been following the care plan that was recommended. We were there about 4 times last year. There were an additional 2 appointments that had been canceled well in advance and not missed. Not really sure how they can claim he didn't follow their treatment plan considering he has several medical and congenital conditions and is under the care of numerous specialists, Very disappointed and disheartened to see how the disabled are treated by this organization. Steer clear!
