This was my first encounter with Dr. Andeyanju. The staff was very professional and efficient in their duties. Dr, Adeyanju was courteous and listened well. He catered to my concerns and gave me sound recommendations. Dr. Adeyanju was not themost 'cheery' type of person, but was rather the type to be professional and get straight to the point- the type that I personally prefer. That being said, I had a good first encounter.
