    Dr. Tweedt 2 thumbs!!

  • Aug 10, 2021

    Dr. Tweedt is EXCELLENT! The feedback in the community is very positive and people speak highly of him. However, they mention "if you can get through the phone lines" which leads me to believe I am not the only one who struggled. One time I called and got no answer so I let it ring while I drove to the office. I walked in and the two girls were sitting there. No one was in the waiting area. I didn't understand why no one picked up the phone. After I saw this, I had to leave because so I didn't say something I would regret later. In the end, the challenges were worth it. Dr. Tweedt did an amazing job with my surgery, and was incredibly understanding and reassuring as I was very nervous. I am grateful.
