Dr. Sharon Marie Ondreyco, MD

Doesn’t care at all. Worst front desk. Sue treated me like garbage.

Dr Ondreyco left her practice without contacting her patients. I am attempting to find where she is now practicing, so that, I can continue my care. She is a brilliant doctor

Drove an hour for chemo, she was covering for my doc who is amazing- there was an error with my labs and she decided to cancel my chemo. This was a big deal for several reasons but giving her the benefit of the doubt, a phone call would have been nice, Instead I sat there and cried in front of strangers and drove an hour home.(Gas is $5:00 a gallon btw)

Dr Ondreyko was wonderful. Straight and to the point. Answered every question. She will always be my oncologist. If you are looking for a dr to sugar coat whats going on, she's not your doctor.

Dr. Ondreyco has been a compassionate Dr. and the team at Arizona Oncology has taken the time to care for me on every level showing me how to regain my life!

Dismissive to my concerns. By reading the reviews it seems like she is only interested in treating textbook cases. If you are in need of anyone knowledgeable with rare blood disorders or other symptoms related to blood she is not the doctor. She has a very bad bedside manner and seems uninterested in your genuine concerns. Almost laughing at times.

I found my breast lumps about 3 weeks after I moved to AZ. I left all my doctor's in IL and was feeling very lost. I ended up at Mayo because they had treated my husband (Rochester). Then ACA came along and I lost Mayo, too. Thankfully, I found Dr. Ondreyco! She is an absolute gem, straight forward, concise, & very caring. I've been seeing her for 4 years and never has regretted my choice in choosing her as my oncologist. I'd give her 10 stars if I could.

She explained my condition.very well. She relieved all anxiety.. I left feeling very positive..it was a good expierice.

I came to Dr Ondreyco as a two-year breast cancer survivor struggling with quality of life and side effects from tamoxifen. She never spent more than 5 minutes with me to offer other medications (Aromatase Inhibitors) or to answer questions about risk of recurrence or preventive measures. After four visits, I'm searching for a new oncologist. I would hate to deal with her or the cold, impersonal staff if I have stage 4/life-threatening cancer.

Dr. Ondreyco is very straight forward with your diagnosis and prognosis which I like. I have been her patient for over 20 years for Breast Cancer treatment. Personally, I think the woman walks on water.
