Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

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

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

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

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

Knowledgeable and Caring
I’ve been seeing Dr Grewal for about two years. She has been helpful in getting my prescription at a fair price and gave me tips on drug interactions. She is caring and takes time to listen to your concerns.

Shameful Front Office
I’m sure Grewal is alright- but when you pay less than living wages to the mob up front-you get what you pay for. A sign of the times that as an md is sought, the front office has to be evaluated

Dr. Grewal is an appointment Nazi. I missed two appointments. She discharged me. I admit that I am human, but I was going through breast cancer and needed her help with my thyroid disease. What an awful, entitled person, let alone physician. Shame.

Best Dr. and staff EVER ! I was referred to Dr. Grewal by my primary doctor and I'm so lucky and could not be happier. All of Dr. Grewal team members are so kind and understanding. They made me feel very special from the very first call to when I arrived they took time to listen to me. Dr. Grewal was so professional and knowledgeable. She spent so much time listening and to everything I needed to say. Amazing ! Thank you all for being so kind.

I have been Dr. Grewal's patient and appreciate her knowledge, promoters and her straightforward manner. Her knowledge is impeccable, she is caring but not enabling. I am so very happy to be her patient.

Never have I had such a disrespectful, inconsiderate, unprofessional doctor in my life. I have no thyroid & depend on Synthroid daily. A month ago I was due for a refill. Dr Grewal denied it because she said I was due for a check up but they could not fit me in for 2 1/2 months. After multiple phone calls, she refilled 1 month. Now I am trying to get another month, but the office says I am no longer a patient. What? Why would a doctor do that?!!! Please do not go to this Doctor!!!

I disagree w/ the negative comments. She is a cordial, but serious and thorough dr. That doesn't mean she is uncaring. She completely changed my health for the better. She was very diligent in stepping through everything I was taking (on multiple occasions), when I was taking it and many other questions- adjusting my meds until perfect. I recently brought in an insurance form and she completed it and faxed it w/in 24 hrs. Insurance Co. confirmed my evidence of insurability in < than 1 wk.!!

My daughter has had some hormonal issues that she has been dealing with, and we feel very fortunate to have found Dr. Grewal. Dr. Grewal has been extremely diligent in determining the root cause, and has taken the time to discuss everything thoroughly and astutely. I'm not sure where the comments about her being condescending are coming from, other than that she does speak to her patients with intelligence, but we really appreciated her explanations and found her to be very caring and warm.

An uncaring doctor. Her staff seemed good and professional but she is one of the worst and we have seen many. Several reasons, but the main reason which was unheard of until Dr. Sonia R. Grewal did it was that she told her staff to cancel a new patient appointment just because there was a call to her phone. One call to her phone and she disliked it so much that she even did not want to see the patient. We are thinking to complain to the Board, these kind of uncaring "Doctors" need to be known.

After 30 minutes I got to see Dr. Grewal. I had some lab tests and we throughly discussed my issues. She was very comprehensive, even told me I'd been taking one of my pills wrong. She ordered follow up test and scheduled another appointment. It was obvious that she is a smart lady.
