This shows a disregard for the convenience and the time of his patients/customers. It's only gotten worse since he joined Sutter, because you can no longer call his office and email takes forever.

At that time she thought she's soon to die coz every movement she makes she's having a hard time breathing . She's very frail and literally can't do anything . We went here as recommended by a friend. He wasn't at Sutter yet at that time but he took my moms insurance. First time we saw him, we got really comfortable with him. He's very nice , even if my mom doesn't speak much English he's very patient with her. Assured her once she got "fixed" she will feel 10 yrs younger. It turned out my mom has problem with her heart valve and also had atrial fibrillation . So they did surgery and yes he's right ever since her operation she can really move a lot without having difficulty if breathing . Now my mom is ok and my dad is being cared by Dr Olowoyeye with all their heart needs. I have deep respect to this doctor . He takes his time knowing your problems and talk to you about ur health. He knows all his patients and very patient with his patients . The clinic is nice and clean . All his staff are very competent and do their job well compared to other doctors offices . We love you Dr Olowoyeye.
