    Dr. Cedars provides exemplary care. She listens to patients she is communicative she spends time with you and truly cares for you not only from a health perspective but as a person. I wish all doctors were as thoughtful and took the same time and care with their patients. I feel truly lucky to have her as my doctor - she has helped me through a difficult time with fibroids and now helps ensure my reproductive and women's health are all in great order.

    It was obvious that Dr. Cedars studied my past medical records in depth before seeing me. She Is the first RE who commented on my embryology reports from other clinics.

    I asked for the clinic to do all options for improving the chances of my embryos in the last round of ivf then in this appt the doctor informed me there was one more thing we could try for the third round. I feel misled and like the clinic is just trying to get money out of me.

    Dr. Cedars made me feel like I was in great care. She took the time to explain the procedure and asked if I had any questions.

    She spent most of the time on the computer. I don't think she knows who I am and I feel like nothing but a dollar sign. Visit lasted less than 10 minutes and was totally useless.

    This appointment was scheduled couple months ago none was available when I scheduled. They based on my test results to discuss my situation I understand. But they didn't even want to do ultrasound for me based on my not accurate number but I insisted to so they did but not very detailed.I didn't feel very confident about what they said. I'm sorry to say I don't feel worth for this time visit.
