• This was a follow-up visit with the doctor and I am pleased with the visits I've had with him. He's very thorough. He goes over and we talk about whatever issues we need to do. So again, I would rate very highly this doctor.

• Dr Kletenik is the best, most compassionate, articulate, professional doctor I have ever been to with my mother since I can remember. It was an amazing experience given the fact how overwhelming the dementia journey is. Truly, I must say it is very touching to see and rare for the doctor to come out, greet the patient and her family and walk them to the room. Thank you.

• My diagnosis was very scary and, to me, complex. I left my appointments feeling very informed and sure I was in great hands. Everyone I encountered was humane, competent and professional. Bravo.

• We were provided with much information about my situation. Dr. Kletenik answered questions we have been asking other professionals for years with no success. My wife and I are so grateful for the in depth assessment and can't say enough about the value we feel is available at Brigham and Women's which enabled this provider to reach out/go back and find records of my medical history.

• My experience was excellent as it has always been. The only problem I have is that he recommended appointments with other doctors and I haven't been able to get any of that information from patient gateway.

• Oh, my experience with Dr. Kletenik was very good as usual. This time my husband was there too, which is generally good, but it was a little challenging this time. And it took some of my, shall I say, focus on what was going on away. It also at the same time illustrated some ways that I'm getting less focused on words that I'm supposed to pick out as kind of a psychological and neurological test. I did not do as well.
