As usual. However, the receptionist needs to learn how to speak up more. I have a hearing difficulty and I had trouble hearing her. She also was looking at her screen all the time she was trying to talk to me and I’m not sure whether she can learn how to pay more attention to incoming clients.

I was in terrible shape when I first saw Dr Lock. I told him my story , He Listened , really listened. He did many tests,and it turned out I was misdiagnosed. Now that I’m treated correctly I have improved 90% and keep getting better. He is a great doctor. He may have saved my life.

He always listens to me. I give him details about what I have experienced/am experiencing and he orders rests from that and then we move forward from results of tests!
Thank you Dr. Lock. I have been seeing you since 2020 when I had Covid-19 pneumonia. Have seen you many times. Thank you for always listening!

I had my first visit with Dr. Lock this past week.
Dr.Lock took his time with me, never seemed rushed and answered any questions or concerns that I had. He was very professional and knowledgeable and made me feel very comfortable with any decisions he made on my behalf concerning my health.
I would 100% recommend him to anyone I know that would need his practices
