"My first impression of Dr. McKenna was that he actually cares for his patients and wants them to succeed. Even since my RNY, he is still a big part of my journey, and is there with me every step of the way. His office staff are very helpful and compassionate. Dr. McKenna loves to give hugs and treats you like family. I would rate Dr. McKenna a 10 on a scale of 1 to 10 with 10 being the best. In my opinion sugical competence and bedside manner equally great. "
