Dr. Onandia is the best chiropractor you can discover here in Corona, CA. He is knowledgeable and has miraculous methods to fix a strained neck and shoulder. I have a history of needing adjustments throughout my life but never have I had one that understood every muscle and ligament that was injured and identified the problem within a brief examination. This doctor is personable and has a great sense of humor! His staff, especially Michelle, is caring and friendly!
How fortunate I am to find this medical treasure that does away with PAIN!

I was referrred from very happy patients, I was pleasantly pleased with his staff's friendly, personal and professional professional help. All COVID19 precautions comfortably in place. With decades of neck and back pain, Dr Onandia was a cut above the rest. I've never felt pain improvement as I did after my no-charge consultation with "Dr O". No expensive tests. I'm sure relieved I found this doc and his staff.
