Every day I see patients who are anxious about their disease, and usually fearful of the surgery they need. I am honored to be in a position where I can help them and make them well again. I go home knowing I made a difference.

Patient Reviews

I can’t say enough good things. Dr. Eigleberger was kind, patient, and worked extra hard to accommodate me. She answered not only all my questions but all my family members too. Everything turned out exactly as she said it would at the very first appointment. She did an amazing job with my surgery, no surprises or complications. I would 110% recommend her to any woman needing breast surgery! I really appreciate Dr. Eigleberger and I’m so grateful she is right here in the east Bay Area!

I was diagnosed with breast cancer I was seen very quickly by your office. I felt every effort was made to make the process go smoothly. I felt I was provided with good information and options to consider.

Dr. Eigelberger operated on a malignant tumor in my left breast using a guided excision technique. She has excellent skills as a surgeon and took time before and after the surgery to be sure all questions were answered. I could not be more pleased with the results! I would highly recommend her to anyone facing breast cancer!

I found Dr. Eigelberger to be very efficient, kind and supportive.  She explained everything about my breast cancer surgery in detail.  Very informative.  I had a very peaceful experience as I felt Dr. E. took special care of me! 

It’s very common to not receive any type of customer service, these days. It was refreshing to work with a team of professionals, from beginning to end. Every person I interested with, was informative, thoughtful and kind. When going through surgery, there is enough stress, having A+ care makes it much easier. I truly appreciate the care I received!

The entire staff of WCSA is great and professional. Dr. Eigelberger is a smart, kind, excellent and highly recommendable surgeon.
