  • Hi, yeah, Dr. Tarkan was okay, but he kind of rushed us. This is actually [redacted]'s daughter, [redacted]. Mom doesn't, you know, she doesn't really, isn't coherent enough to take surveys. [redacted] He does seem to know his stuff. And, you know, just kind of, I just didn't feel comfortable being rushed through the appointment so quickly. And it was my first time. [redacted] that's how I'm feeling. Thank you. Bye.

  • Dr Tarkan has been my provider for 8 years. He corrected me with a smile: "For 13 years!." He saved my life from high BP and has been thorough about allaying any blood work results that seemed iffy to me. We don't need to speak much at appointments because my BP has been under control because of the meds-and the amount--have been adjusted perfectly for me body, weight, age. Dr Tarkan is clear about how age factors into the adjustment of the rise in certain numbers that, 13 years ago, might have needed pro-active attention. He's professional, always familiar with my progress, has the lab results sent to me usually within 48 hours with an encouraging note.
