Horrible doctor. Rude and unprofessional and Dosent care about his patients. I would rather deal with my own allergies than to deal with him.

Rude miserable person. He doesn't do his job period. Doesn't know anything . Makes you feel like a burden. He can not and will not help you because he doesn't want to. Waste of time and sutter should dump him. Don't waste anytime with this mean unprofessional uncaring person. All my other sutter doctors are amazing and appreciate all they do for me. Pass on mark grijnsztein!!!

Poor follow through on providing promised resources and information for dealing with food allergies. Requested them twice, he promised twice, never did it. Inattentive and distracted. Bungled lab orders (ordered outdated tests). Took him forever to admit it and still wants to argue about it. Not familiar with newest research or testing and not about to admit that! Simply cannot speak to current issues. Sub-par in his ability to answer questions in a direct and timely manner. Talks constantly, but does not come to a point, answer the question, or take a position. I've seen this doctor for over three years and I finally go totally fed up with never getting a question answered directly or a professional opinion rendered. He gives the very strong impression that he does not take food allergies seriously and would prefer to not deal with them. I've found it worth the time and trouble to find a new allergist.
