*Dr. Spencer did my R. shoulder in 2020, now I need my L. shoulder done, and I'm very pleased with the care and follow up and I did very well, so I hope the L. shoulder will do the same.

Dr. Spencer did a great job. I felt for him as a previous leader where a patient before me was not cooperative and became a distraction. Dr. Spencer handled it better than I would have with this patient. In other words, the patient would have been politely requested to move on to another provider.
