As a new patient, I received the best care from an experienced and knowledgeable, caring doctor. This office was able to see me before me earlier than my expected appointment. It made me feel that this doctor/office really cares about my health and wants to help and I could not be happier for choosing this practice for my continued treatment

I was in very bad Stomach/Gurd for weeks, and every food I ate gave my stomach a slow response with terrible painful gas, Dr.Sullivan explained the benefits of Probiotic that works in the " gut" the area of bad gurd that takes time to beaks down food effectively, I started the therapy the next day. I was in complete shock how different my body reacted to probiotics, his knowledge (incredible knowing I do not have a gal- bladder) helped my entire Eating, and digestive system is now on positive rhythm is now postive cycle no more pain, no more discomfort, I was complete shock that one intervention, that 3 weeks through my life of wack now was in the past. It because Dr.Sullivan knows the complex working within the Body, and you just need to Follow it, I so glad I was given this change it has made me feel 100% better.
