I was an old patient of his and was hoping to find him again since he went on leave years ago when I found out about his passing. He was an incredible human being who touched my life in so many positive ways in such a short time while he treated me. His caring and compassion was felt through the room and touched my heart in ways that healed so many pending issues with my past, at the time current situation and the love and knowledge he shared about children which has helped me to this day to be a better father. I am saddened and heart broken by his passing and wanted to send my condolences to you and his family.

A true loss for humanity and a community that he served and the family that he left behind....I truly could not bring myself not to express such great encounter in my life.

I wanted to reach out and express my condolences, but more so, my praise for Dr. Kelleher.

Your husband was a wonderful therapist, and without his bi-weekly support at the beginning of my sobriety, I'm not sure I would be here. I am so sorry that he is gone so soon.

Thank you for making his obituary public. It's beautiful to learn even more about what a lovely and warm person he was. He was always so kind, compassionate, funny, understanding. And he had impeccable manners and a high tolerance for antics. .... Clearly, your husband is a saint sent from the Gods....

Anyway, thank you for sharing him with the world while he was with us. I hope your family has found peace since his passing. I don't have the right words but felt it was important to say something.

Again, I am so sorry to hear of this tremendous loss. Dr. Kelleher was an amazing guy.
