Rocklin, CA |
What an incredibly rude Doctor. He walked in sat down his intern shook my hand introduced herself. He truly must either hate his job or working with people! A complete waste of my time and resources to drive an hour to this man! I reminded him several times my doctor referred me to him. I finally asked him "what am I supposed to do when I can't breathe?" I called my insurance I'm not paying for this visit. I called his office and complained as well.

He barely looked at my chart. He walked in without a care in the world for my concerns. I walked out with a half baked diagnosis that I don't believe. I am most definitely getting a second opinion. How can anyone trust someone who doesn't appear to care about you?!

Dr. Grijnsztein was one of the worst allergy doctors I have ever seen. After waiting about 20 minutes to see him he walked into the room with an attitude like he didn't want to be there. Very unprofessional, rude and obnoxious. If your not good with people and don't like working with people than get a different job. I would rather have allergies than deal with this short insecure rude "doctor" ever again.
