Dr. Dar's office was the most insensitive I have ever seen. I went in for a blood test, and right away they asked me if I had a will and directed me to fill out information about next of kin. They said it was just their policy. I worried for two weeks, until my tests came back normal. Their policies are wrong, unethical, and inconsiderate to patients. They need to be changed. I will not return to this office.

Dr. Dar has been my mom's Oncologist for 5 years. My mom is a 2 time cancer survivor, both cases caught in aggressive stages. Because of my mom's treatment, she's had to try experimental therapies and work with a plethora of specialists; this has given me perspective and the juxtaposition I need to give an educated review.

Finished chemo for HER2+ advance stage 3 breast cancer with another doc. Transferred to Dar after not being informed of high bp, etc. Dar argued with me about getting any testing, didn't know what kind of cancer I had after 3 visits, and (office policy) wouldn't call for a pre-authorization like other docs. Wouldn't do a peer to peer to get PET scans with insur after they denied me cause Dar only wrote a scan for neck to pelvic area. HER2+ comes back in the BRAIN! Seeing another doc with sense!!
