First visit, I waited almost an hour to see Dr. Horner. I spoke with him for 5 minutes, and I got a visit summary stating he spent 1 hour with me. Scheduled follow up 6 weeks later, per recommendation. Was called a few weeks prior to say Dr will be on vacation, best option was PA 8 weeks out. Got several e.mails/texts to confirm appt - which I did. Arrived for appt, and waited in exam room for 45 minute before leaving. Asked to reschedule and was told 2 months out. TOTAL DISRESPECT OF PATIENT TIME.

He is an awful doctor. He seems to only be about money. He hardly talks to you, doesn't go over necessary information, and allows his TERRIBLE assistants handle everything. These assistants scheduled my husbands surgery and told us it was 100% covered by insurance. Because his assistant Stephanie seemed incompetent we check 3 times to BE 100% positive that this was covered! We even asked the facility before any surgery took place. Low and behold we received a bill from the Tracy Surgery center.

He is the most awful and arrogant SOB you can ever come across in your lifetime. After making me wait more than 90 minutes for the appointment, he walked into the room, did not even examine me, never made any eye contact let alone say hello, and just looking at the charts, he said, "Surgery. There's nothing I can do for you but surgery." And then walked out of the room before I can respond to his utterance. Did I mention, he didn't even close the door so everyone could hear him?

Worst experience, he'll spend about 3 to 5 mins with me, he never knows why I'm even there since he never looks at my chart. Would give him less than 1 star if I could. He says he's checking on something, leaves & never comes bk. Twice I came out to the hall & he was putting his jacket on & leaving the office! Wow.. So uncaring, totally not doing this because he cares. He'll offer meds, cortisone shot, sent me to physical therapy with WRONG info, they were going treat the wrong body part. Beware

Worst doctor I’ve EVER been to. First visit, waited an hour. He poked the lump in my wrist, and said, “I don’t think that’s a ganglion cyst. We need an MRI,” and left. Visit was less than 3 minutes. MRI cost us $300 out of pocket (plus $20 each copay). Second visit, waited over an hour. No MRI results, but he said I just needed a cortisone shot. So why the MRI? Week later, hand still bruised and painful. He is incompetent, uncaring, and arrogant—a dangerous combination. STAY AWAY!
