Doctor gave me a 5 minute lesson on the condition I've had for 26 years. But did not get to know me. I am just a lab report. I am going back again in 2 months. My old doctor I saw once a year. I guess Optum needs multipule visits to make money,

He cared very much about what was going on with my health and really took the time to listen. Very thorough with responding when I messaged him on the portal with an actual phone call to explain everything I questioned. Overall, he’s a wonderful doctor and I’m very happy that I was referred to him.
