Dr. Kronick is Board Certified in Orthopaedic Surgery and has 17-plus years of experience in treating patients. He began practicing orthopedic surgery in 1995 after completing his medical training at the Chicago Medical School and his residency at Wayne State University in Detroit.

Following residency, he completed an Adult Reconstruction Fellowship at the Rush Orthopaedic Institute under the direction of Wayne G. Paprosky, M.D., where he advanced his skills in hip and knee replacement, revision hip and knee surgery, and the management of bone loss. He then performed a Biologic Hip Reconstruction Fellowship at Wayne State University under the tutelage of Jeffrey Mast, M.D. and Keith Mayo, M.D. where he refined his skills in the art of osteotomy and internal fixation.

Following his education, he joined the faculty at Wayne State University as an Assistant Professor and was named Teacher of the Year in 2000. Dr. Kronick’s special training and experience make him one of the best joint replacement surgeons in California.

Dr. Kronick has been the best orthopedic I have came across. He showed worry and concern for my diagnosis. He has been proactive compared to other doctors about his patient’s heath. Look forward to continue working with him.

Dr Kronick is an excellent orthopedist. He spends time with you and your family explaining the pathophysiology of the injury and his approach to addressing the problem in a relaxed way. You don’t feel rushed. He is focused on you as his patient. David PA demonstrates the same qualities.

Dr Kronic is an assume Ortopedic Surgeon. He has fellowships and other extensive training specializing in knee and hip surgery. Meaning he is an expert in his field. He is also the guy you what to see if you need a revision. I have gone to Dr. Kronic for both knees and hip replacements with great results. He's a very caring person and listens to all your needs. He takes the time to go over everything. Pain management is great after surgery. The Golden State outpatient rehab group is great. I highly recommend Dr. Kronic for all your joint issues.

I am writing this letter of thanks and recommendation for Doctor John M. Kronick, because through his professional knowledge and skills as a surgeon, he has made my life and my daily physical living conditions enjoyable again. I have worked hard and been a very outdoor active person my whole life and it took it's toll on my knees. Doctor Kronick has replaced both my knees in the past three years and because of his professional skills I can now move and run without any pain, sleep through the night without waking up saying ouch and I can now chase my grandchildren. Doctor John M. Kronick in my mind is a life saver and miracle worker and I want to acknowledge him for his professional as an outstanding Orthopedic surgeon. He's the best!

Dr Kronick is an amazing and kind surgeon. He explained the process and helped set expectations. I never second guessed my decision and he delivered as promised. He corrected my leg length discrepancy made a beautiful 10” incision, even better carried the line from my previous surgery and I’m healing nicely. I would definitely recommend Dr Kronick to anyone he is the absolute BEST! Thank you!!! :)))
