I have been seeing Dr. Alverez and Pfiester since1983. I highly recommend them. Dr. Alverez has worked with me to perfection to make sure I see as clearly as possible. I wear contacts, if one doesn't work , she is ready to try another one. She gives a very thorough exam and I wouldn't go anywhere else. She also cares about her patients overall health and happiness. I just want to thank her for helping me able to see and all she has done for me. She is more than my Dr. She is my friend.
