LILLI ANN C. CELLONA, MD REVIEWS

Dr Cellona is amazing! And her staff is super friendly and helpful. I was seen before I even finished my paperwork. She seems very knowledgeable and has a great personality. So happy I went here.

She’s been my doctor for years and is always available for me over the phone, online or in person. Love her.

I went to Dr. Cellona for the first time a few days ago. Unlike most (just about all) doctors, she saw me on time. She was knowledgeable, thorough and personable. She devoted the necessary time to my appointment. I highly recommend her.

MICHAEL ANTONY OLERICH, MD REVIEWS

I am diabetic and under the care of Dr Olerich with Kaiser Permanente for over 10 years. I found myself very fortunate for having such a caring doctor. Dr Olerich is on top of all my test results and always responsive to any question and request that I have. That is a very positive luck when you are with Kaiser.

Excellent Endocrinologist, I have been seeing Dr. Olerich for about 25 years. He has taken such good care of my Diabetes.

Dr. Olerich was kind, professional and very knowledgable. He took time to explain things to me, something I find other Dr.'s often fail to do. He is competent in his field and my health has improved since receiving his care.

ALEEM SYED, MD REVIEWS

Dr. Ahmed and the front staff. The front staff is very helpful. Specially Diana. Dr. Ahmed goes above and beyond every single conversation/appointment. She has called me on her lunch or even after hours on many occasions. She takes the time to warn you about side effects, she’s considerate, knowledgeable and cares about her patients tremendously. Thank you.

I thought she was very good and thorough. She helped me with my problem.

The service at this facility is saving my life. Thanks to all the doctors and nurses. May GOD bless you all.
