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

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.
