I had a very pleasant experience when I met Dr Sheridan for my first consultation and check up. A week later I had an emergency and Dr. Sheridan saw me that day and set up all the auxiliary appointments needed. He called a few days later on a Sunday morning to check in and give me results of tests. I am grateful to have someone in my court who is looking out for my best interest. I feel like I found my " Dr Marcus Welby"!! ━ Shoshana K.

From the first time I walked into Dedication Health and met Robert, Susan, and Amelia, they have made me feel welcome. I love the look of the office; I love Dr. Croghan and all the great care he gives me; and, I love the fact that the CT Scan and X-ray equipment are on-site." ━ Bill K.
