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
