Dr. Thu took his time and explained his thoughts and wanted feedback on how my care was completed. Wanted to know if I understood what we covered. Great visit and came away with better understanding of my course for treatment. Great job Dr. Thu and staff for making a visit feel like talking to someone who cares.

Service was exceptional from making the appointment thru seeing Dr Thu. Doctor went beyond my expectations. I felt that I had a thorough exam and he explained many concerns and findings. My fears were alleviated by the time my appointment was over. Mentally this was such a relief. Plan of care was thoroughly explained and I was allowed to ask questions. I was well pleased with Dr Thu and staff at the office. I look forward to my future visits and feel confident that I will receive an individualized plan of care that will benefit my problems.

Doctor was so well informed we knew he had looked at my husband records and was on top of everything. I felt so good when we left as I had a little worry about my husband's memory issue, but he explained everything told us how to go forward said he didn't need any additional medicine. I was thrilled. I am not in denial so I know there was a problem, but now i am so relieved and know how to move forward. We have been with doctors in St. Louis for many many years and when [xxxx] got sick and we rushed him to Memorial. My eyes were opened it was a wonderful experience from the hospital to rehap and then I changed to local doctors we are so satisfied with everything so far with the follow visits and now he is almost to the end of his therapy. I am looking forward to Spring and his recovery didn't know for a little bit if there would be one. Thank you all from the bottom of our hearts we appreicate you so much
