Receptionist was aware of my arrival, acknowledged presence with a smile and pleasant voice, doctor assistant conducted testing with ease and accuracy, and when Dr arrived in room with such warm smile and deep concern for my health needs, I knew I was in good hands. I will refer this business to my friends when needed.
