    He is great, but I honestly am too new of a patient to truly say. I am happy thus far so I would if somebody asked me, but I don't have much to go on and I'm somebody who typically only recommends if there's substantial history. However, I am happy with my care thus far.

    Have seen Dr. Riffer for approximately 40 years. He is a knowledgeable, courteous, and concerned physician. I’m not sure what anyone else would want from their doctor.

    It seems my instructions for ordering my medications was not followed. The Meds were not sent to the correct pharmacies I still do not have all my medications. The Flomax med has been cancelled by Optum. They need more info. I just sent a message to Dr. Riffer to request the pharmacy mix up be corrected.
