Testimonials from Clients and Colleagues
“I can honestly say that Mark has helped me to successfully navigate what has been the most difficult period of my life. I started seeing Mark as a result of an incredibly difficult end of my marriage. Mark helped me to see what my role was in the divorce as well as developing a healthy and realistic view of myself. I can often hear his words years after our visits and frequently that refocuses my thought process. He has helped me to develop a smarter internal dialogue. Mark never tells me how to live my life, but rather guides me to my own answers. Mark is very thoughtful and respectful, but he has never been shy about sharing his opinion.”

“Mr. Knippenberg is an intelligent, gifted and extremely hard working therapist. I have been consistently impressed with his ability to integrate several theoretical approaches and his own-going curiosity and openness in using these multiple approaches. Mr. Knippenberg practices with integrity and he is consistently concerned about providing results for his patients.”
Richard Martinez, M.D., Psychiatrist

“When I first met Mark my life was beginning to unravel, but I didn’t fully comprehend what was happening. Mark gave me the time and space to carefully explore how alcohol was ruining my life. When my wife said she was leaving, Mark intervened on my behalf. He showed me how to stay sober and enjoy life without alcohol. Mark saved my marriage and family. I now have new hope and appreciation of life, 2 years sober.”

“We worked closely together on many difficult patients, some of the most difficult I have ever treated, and I always found Mark to uphold the highest professional and ethical standards in treating these patients.  His high level of energy, enthusiasm and sense of humor made him a pleasure to work with.”
Jay Carlson, M.D., Psychiatrist

“My husband of 25 years had already filed for divorce when we first met with Mark. I was still in a state of shock at our first session. We had failed to get the proper help with 3 other therapists. I didn’t think there was much hope, but I was willing to do anything to save our marriage. Mark thoughtfully reviewed our problems and what didn’t work with the previous therapists. We acknowledged that we would ideally like to make the marriage work, but my husband felt that he was basically checked out. Mark told us that if we were committed to hard work in therapy, great things could happen. He gave us numerous reading, written and video homework assignments. I’m still amazed at how Mark got my husband to open up in our sessions. Most importantly, I feel that I know my husband better than at any time in our marriage, and we both feel happy and inspired as we look to our future together.”

“I was consistently impressed with Mark’s organizational skills and sound clinical judgment.”
David Nelson, M.D., Psychiatrist

“Mark has amazing insight and sensitivity. When I thought I had no options, Mark enlightened me, helped me along a path of self-discovery and enabled me to find the strength to move forward. Thanks to his insight and guidance, I was able to see the destructive aspects of my previous relationship. He taught me a simple technique to effectively evaluate the potential of new relationships. Thanks to Mark, I got relief from stress, regained my perspective and was able to regain joy and balance in my life.”

“My sessions with Mark have been an integral part of my recovery from alcoholism. Mark has assisted in helping me manage my day-today life without the use of emotional anesthetics (i.e. alcohol). He has taught me how to approach stressful situations and people with peace and confidence.”
