This clinic has been one of the most frustrating healthcare experiences I've had as a parent…read more At our first visit, they did not have the vaccines available. The doctor ordered blood work on my 11-year-old. When I asked if there was a reason, the answer was no--just because of her age. My daughter is a healthy athlete, and this felt unnecessary. At the second visit, when the vaccines were finally in, I was pressured to agree to additional shots that weren't required, and treated rudely when I refused. My daughter, who is already fearful of shots, was quietly crying. Instead of offering comfort, the nurse spoke to her harshly, told her to stop, and warned that if she moved it would hurt. This only frightened her more, and afterward the shots were painful for days. Experiences like this make children lose trust in doctors. Even worse, the vaccines were not entered properly in the state system. After the second visit, the school nurse checked twice--first finding nothing entered, then later finding the records locked. She explained only the clinic could lock or unlock them. I had to go in person just to get a printed copy. It felt like unnecessary hoops to jump through, made worse by staff who were sharp and unhelpful. The only helpful person in the office was the front receptionist--kudos to her for finally getting us the printed records. My daughter is not a paycheck or a pincushion. We will not be returning, and I would not recommend this office.

He quit Optum because of its management within 9 months. Seven months later, I got a third PCP. He stuck around for a whole year! Then without warning, he retired. Now they tell me it is a nine month wait to "get established" with a 4th PCP. 4 PCLs in 2 1/2 years! What could possibly go wrong? I fired Optim for poor performannce. Go anywhere else.

Despite many many calls for help with physical therapy and speech therapy, It took months to get help while his condition declined. He is now getting occupational therapy. Medical professionals (other than Optum) have told us that he should have been in a stroke recovery rehab center. Watching him decline, hardly able to speak is heart wrenching. Still no speech therapy! Every call comes with excuses, no help! Warning, never sign up for Optum and if you already carry it, change your coverage!!!
