Reviews for William J. Nienaber, MD

He was very attentive and cared about my well being.

Friendly and thorough

Seems to care about his patients

Very professional and seemed like he was invested in me as the patient and willing to look into it further. Set me up for an echocardiogram and they called me the next day with the appointment. Very fast referral thank you

Visit was well reccomendations were made and received. He did tell me he would renew my meds i was taking but so far they have not been called into my pharmacy.

He is a friendly and competent doctor.

Answered all my questions and developed a good plan for my future

Very patient during all my questions. Very knowledgeable, professional, and friendly. Easy to talk to and didn't rush through the visit. Very down to earth. I was impressed with how he treated me as a person and not just a number. I will definitely recommend him to others who are in need of a cardiologist!

Dr. Buenaventura is always very friendly and thorough. He explains test results and plans for future visits.

Was very nice got in and out with very little waiting time
