“My first appointment went amazingly well. The office already had my information on file and the staff were very friendly. I was able to check in early and do all of my paperwork ahead of time. The wait was less than 5 minutes to be seen. Dr. Nnaji is a good listener and cares about the health of his patients. He allowed me to ask him questions about any concerns that I had. I got my annual physical done and bloodwork. The whole process from start to finish took less than 30 minutes. ”
