Dr Denboer helped me immensely. He helped me with processing information handed down from my coaches and applying them better on the field. This has made me a better player all around and I am very happy with the direction I am heading.

I’ve been working with John for 4 years now and he has taught me so much from changing my mentality when I’m on the court to even my personal life. He’s a great mentor and a confidant and he is always there when I need someone to talk to. He’s helped me tackle things in vulnerable phases in my life and I can’t thank him enough for all of the things that he has done for me. John is a great friend.

SMART Aging

My experience has been very positive with Dr. John DenBoer. He is respectful and has a great program for me, with being a Post Traumatic Brain Syndrome survivor 37 years now. This has included anxiety and elderly symptoms and this program, along with Dr. DenBoer’s manner, is just what I needed. I feel he is a true professional having earn this opinion from those whose lives he has touched. At the suggestion of Dr. John DenBoer my partner has enrolled in the “SMART Program.” In the past three months, we have seen significant improvement in his attitude and willingness to interface with people. The results show significant affect change after each session and the days to follow. Yes, this program has helped, and has provided a lot of encouragement to both my partner and I.
