“I visited Rios Healthcare yesterday for my wellbeing check as part of my business visa requirement. My appointment was with Dr. Nicolin J. Neal, and he was extremely professional and knowledgeable. He knew exactly what needed to be done for the examination, including the physical check, blood work, and chest X-ray, which made the whole process smooth and efficient.
The front desk staff were also excellent. The lady at the reception was very polite, welcoming, and friendly, always smiling and making the check-in process pleasant.
Overall, it was a very positive experience, and I truly appreciate the professionalism and I am strongly considering making Dr. Neal my primary care physician.”

“Everything was great, the only thing was that there is no office staff. You will need to call the main office to have them buzz you in the office because the door is locked. After that the Dr. came in about 5 minutes after and I was seen.”
