Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Absolutely the best!
Not only is Dr. Merlin very skilled, but he also takes time to listen to his patients and to explain his diagnosis and treatment plan. A very rare thing in medicine these days...

One of the BEST!
Dr. Merlin and his team were absolutely the best! During my initial consultation to discuss my treatment plan, I felt at ease as best as one could after having been diagnosed with cancer having been metastasized from the prostate (had a prostatectomy). He was open and addressed my questions without hesitation.When I found out there a location in Conyers, I was ecstatic, but he stated I could attend the Conyers location and would be seen by one of the doctors at that location as he worked out of the Lawrenceville Hwy. (Decatur location). Because of the chemistry (our interaction during this consult), I opted to be treated at the Decatur location. I felt so strongly about it, I drove approximately 60 miles RT vs. 7-10 miles had I gone to the location closer to my resident. I'm so happy I made the choice I did. The side effects from the Radiation treatments which I was forewarned about (possibly), was very minor and I'm grateful. Everyone (staff) were great to work with. Thanks!
