"Thoughtful and attentive experience for my first colonoscopy. Everyone introduced themselves (front desk, nurses, nurse anesthetists, and doctor). They frequently checked for any needs I might have. If you’re not a regular patient at the practice, the doctor will meet you before and after the procedure. I have a medical background but I do not volunteer that info to my caregivers when I am the patient because I’m not at work, I AM THE PATIENT. With that said, be sure to ask questions or have someone with you who will ask questions after the procedure in case you’re thoughts are in the haze from the anesthesia. While the doctor will tell you what he did, removed polyps in my case for example, he did not face to face explain to me what polyps were and why they had to be removed. Maybe there were handouts that explained it but I admit I have not looked at the paperwork since leaving there. Even so, any handouts should reinforce what the doctor has already told you, in my opinion. Overall, I would definitely recommend this practice."

"I truly appreciate and enjoy the services of Dr Brennan. I have been to several other physicians in an effort to at least get an idea of what was causing my unbelievably painful stomach pain and digestive issues, to no avail. To be honest I was being handled like a lab rat. Not one of them were able to give me any definitive answers or even feedback. After going to my initial consultation with Dr Brennan I felt like I was in good hands. He was very easy to talk to and he understood my dilemma. At the end of the visit he looked me in the eyes and reassured me that, “we are going to find out what is going on with you together”. I am very excited about being his patient and I look forward to working with him. I highly suggest or recommend him for anyone who has abdominal issues."
