Dr Z and his staff are amazing! Dr Z has been treating me since July 2025 when I was told I would need double knee replacement. So far I've avoided surgery and can walk without pain. I feel like I have a partner in my healing!

I have been wanting to leave a review for Dr. Z for awhile now, but its been hard to put into words exactly what he has done for me and how he has helped improve my quality of life. I work a very physical job and from sports injury, over-use, and general wear-and-tear, my shoulders are shot. I have been told by an orthopedic surgeon that I need a double shoulder surgery and unfortunately because im only 35 im too young to have it done... Dr Z actually takes the time to understand your specific situation, and what your needs/goals are. Not only is he an excellent chiropractor but just an all around great guy. I feel he goes above and beyond the standard. I used to be in constant pain, just sitting completely still my shoulders hurt. He has helped me eliminate so much of that pain and my range of motion is also improving. Im excited to continue my StemWave treatments and see just how much im able to recover, without surgery! Thank you again to Dr Z and his staff!

After years of seeing specialist for chronic back issues and surgery, Dr. Z has been beyond helpful. He takes the time to understand the root cause of issues and puts together a thoughtful plan that works. The office is relaxing and a great location in Lebo, highly recommend Dr. Z!
