I have been with Dr. Thomason for nearly 20 years and my experience has always been excellant in our appointmnets and care. She listens and looks up my past tests and exams and takes the best care I could ever hope to have with a physician. I wish there were more like her in medical practices. My experiences have been very good at every appointment.

Dr. Thomason has always had the time to spend with me, answering questions and/or making recommendations. I will always make an early morning appointment, because if you make a later appointment, you may have to wait longer than 15 minutes as she is taking the time to discuss, recommend and/or solve a problem or answer a question with someone else. Over the last 12 years, she and her staff have provided excellent service and care for their patients.

We set a goal to lower my blood pressure so I wouldn't need to start medication. I did it and Dr Thomason and her nurse were really happy and treated it as a huge success. Great personal care!
