Dr Kennedy was wonderful. He took the time to explain and answer all my questions.

Reviewed on Feb 19, 2019

Dr. Kennedy was one of the least caring endos I have seen. Despite being a self-proclaimed specialist in Cushing's (which is why I specifically decided to see him) I feel like he really doesn't have a grasp on the disease at all. I also, don't appreciate being told that I'm just eating too much and I just have a weight problem when I have many critical health concerns that are affecting my life and health daily. Instead of trying to get to the bottom of what is affecting me, he brushed off my concerns.

Reviewed on Feb 18, 2019

I love Dr. Kennedy, he has always been very kind, professional, diligent and showed genuine care for my health. Because of him, I now feel much better than how I felt 5 years ago.

Dr. Kennedy was absolutely excellent & caring. The time he took with us at this initial visit with a lengthy history & labs was exceptional. He made every attempt to get a handle on our case & explain things to us. His manner is caring & gentle. To have a Dr. his Calibur type all the notes himself we had never experienced before. We felt we had the best care ever of any doctor seen. He was absolutely precious. We love him for it. Where we live we wait 6 months for a 1st visit with an endocrinologist & then be rushed with 5-10 minutes at each visit thereafter. Thank you Dr. Kennedy. Can hardly wait to see our test results & see where we go from here.

Reviewed on Sep 27, 2018

Reviewed on May 31, 2018

Dr. Recino explained to me that I did not need a neurosurgeon at that time and arranged for Dr. Kennedy to see me instead. Dr. Kennedy saw me in a very timely manner. I did not have an appt with him and he fit me in anyway. I drove from 3 hours away so I was very happy about being able to see the correct specialist during the same office visit. It worked out wonderfully for me.

Dr. Kennedy came in right away. He told me that there will be no need to follow-up with him. He ordered the TSH lab test and the results were favorable. I thought he would consider ordering the T-Periodase test too. Nevertheless, I felt better after following up with him.

Reviewed on Apr 21, 2018

Dr. Kennedy showed up around 30 minutes late becuase he apparently forgot he had a patient that day. Worst of all, he didn't seem to care, and didn't even stay long with me despite me having to wait 30 or so minutes for him.

Reviewed on Apr 18, 2018

I would highly recommend Dr. Kennedy. He is very knowledgeable and personable. He answered all my questions and concerns I had about my health issue.
