in Hudson Co |
The treatment that I received from Dr. Janssen was second to none....The surgical team all worked in unison and provided exceptional care...... His surgical assistant was Dr. Ruth Beckham whom I can not say enough good things about her follow-up attention.....My recovery from spinal fusion surgery was shorter than I anticipated....... I have had no side effects to deal with....... Truly a job well done...
I'm glad to hear that you recovered more quickly than you expected, Otis. I appreciate your positive comments about our team and Ruth's follow up care. Thank you for choosing our practice for your care.

I have had three different spinal surgeons in my life. Dr. Janssenis by far the best surgeon I have come crossed. He took his time to understand my condition, he explained options to me, and he and his staff were excellent during my recovery and treatment
in Arvada, CO |
Dr. Janssen is an expert in his field (research, youtube videos) and a focused, excellent surgeon. The first time we met and he explained his recommendation he said "it would be a privilege" to help me. I have never had a doctor speak so humbly and honestly to me.
in Sarasota, FL |
The best and most talented surgeon out there, I flew from FL to Colorado for my surgery, well worth it. Only go to the best when dealing with something so critical.
