Your trust is our top concern.

We strive to keep the reviews trustworthy, honest & fair.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

I do not usually write a review. However I feel so strong about this that I felt compelled to. If this saves one person from the agony and hell this Dr has put me through than its worth it. I also can not believe I am the only person she has done all this to. She is definitely in it for the money and not the patients. She has cost me years off my life. Has lied more than once to my face. Left me very sick and vomiting and didn't even care. Said she would call in a prescription for nausea and never even bothered. Yet every time you go in the office she has medication after medication for you. I have new Dr's now and what a difference. They explain everything to you. They run test on you. Which is something Dr Halasen said she was going to do many many times but never did. Another lie.

She is an excellent caring physician. She thoroughly explains your condition and treatment options. You are not rushed and feel that she really cares about you. I would not go to anyone else.
