Both of us knowing that my next appointment would be in 366 days it would have been appropriate for Dr Masor to mention that he was retiring so that we could discuss in private an alternate primary caregiver. Really?!?

- 3 out of 5 starsReviewed on 3/18/2025
Dr. Masor used to be one of the best. A true doctor's doctor. He was attentive and focused on patient interaction. Now, his face if buried in the computer screen looking up patient history or entering data. It appears he's half-listening and mostly just listening to see when he needs to refer me out to another doctor specialty.

- 2 out of 5 starsReviewed on 1/27/2025
I guess Dr. Masor means well, but his complete reliance on numbers and charts and his inability, or unwillingness, to observe his patient (me) has reached the point that I want a new primary care physician.

- 4 out of 5 starsReviewed on 1/20/2025
Again, the doctor consultation during the physical was limited in its effectiveness because all of the test results were not available. Instead of a comprehensive face to face discussion with the Doctor, I have had to look at test result updates in my chart where I am not educated on the purpose of each test.

Dr. Masor is always very professional. He listens carefully answering any questions I have and explains treatment options and refers me to a specialist if necessary. I live in Powder Springs and am 75 years old so it is quite a drive to the office but it is the faith I have in Dr. Masor that makes it worthwhile. My mother lived to be 95 and I am convinced she would have died at 87 if not for Dr. Masor's involvement in her treatment after she nearly died at another hospital.
