I've been a patient at Dr. R. Guster office since close to twenty years or better. Dr. Guster has always been the same all these years pleasant and professional. As his patient all these years he has provided excellent care in his profession. I've seen several different dental assistance to Dr. Guster and receptionist but, they too has conducted their self in a professional manner. I have recommended several of my friends, family manners and associates and they all was and some still are presently a patient to him. I will continue to recommend Dr. Guster.
