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.

Great compassionate, brilliant and knowledgeable!
Dr. Armellini spends and has spent a lot of time with me and no question is out of line with her. She has treated me as if I was a family member..She is extremely thorough and very engaging..she will call you at home if you have an issue. I have had thyroid cancer for over 10 years and I am in very good health because of her!! I had gone to another endocrinologist for awhile and he had no idea how to treat me..There was no comparison.. She is brilliant..I am an extremely satisfied patient!!

Very thorough
Dr. Armellini has been my endocrinologist for several years now. She has managed my pre-diabetes with great care and compassion. She keeps abreast of not only endocrinology, but also other medical disciplines as they relate to endocrinology. I always feel that I am in the best hands and consider her my favorite doctor because she is so thorough in my treatment.

She Knows Her Science
I’ve been treated by Dr. Armellini for over a decade. She is, by far, best doctor I have ever interacted with regardless of specialty. She knows her science, figures out your chemistry and puts you in optimal situations. I’ve been admitted into hospitals where the doctors consult her and even they have said on at least 2 occasions, that she knows her stuff.

One of the Best
If you would like to have a kind doctor who cares about her patients and is one of the best in her field, do yourself a favor and make an appointment to see her. If it is your first appointment, she will discuss your concerns and give you plenty of time to interview her to assist you in determining if you want her to help you. Dr A will answer any questions or concerns you may have. She won't be happy until she knows you have all the answers you need to make an informed decision about moving forward with her as your endocrinologist.I am a complicated patient. Dr A is always discusses current health issues and how we can fine-tune my treatment to mesh with treatment plans for my other issues. I am always amazed at how well-prepared she is for every appointment. I am very happy I have her as part of my health care team.

Dr. Armellini, THE BEST Endocrinologist EVER!!!
Dr. Armellini is attentive, knowledgeable and simply caring. Under Dr. Armellini's care I have gone from a number of inflammatory challenges, and A1C that was out of control and was easily 50 to 60 pounds or so overweight. Today, I have reached a healthy weight, my A1C is now much lower to the extent that I am no longer Diabetic but pre diabetic with those numbers leveling out and am healthier and more active than ever! Dr. Armellini takes her time with you to the extent that you feel as though you are her only patient. Provides prompt follow-up consistently and is simply a joy to have supporting me on my health journey.

I have been a patient of Dr. Armellini's since 2012. She is very detail oriented and explains her diagnosis in clear and simple English...giving examples from research to explain the basis for her recommendations. She is very responsive to queries on her patient portal and gives a lot of thought before deciding how to proceed. She has been a great help to me and I feel fortunate to have her as my endocrinologist.
