I recently and regretfully added this doctor as my primary care physician. I had no symptoms of any kind when I first saw him simply to establish him as my PCP and have an initial exam. I am already under care of several specialists. In one very short visit, this doctor added multiple serious disease conditions to my medical record on the basis that he "observed" various symptoms that do not even exist. He is argumentative, does not listen and is careless with health information and records.

Chris Ford in Oxnard, CA – Jul 12, 2018
He is a worst doctor I ever met. He did not call back to my pharmacy for a refill till I, my pharmacy and my other doctor's office called him more than 10 times. Actually I missed some medication. When I got the medication I was charged for $900 which is cash value of the medication because he did not get a preauthorization from my insurance company. His assistant told me she sent all information to my insurance company for preauthorization but that was a lie. She never sent any paperwork.
