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.

Dr. Dejarnatt takes his time explaining everything about your condition and needs. He also is great to ask you to call back and do an update with your condition to make sure you are doing well. Great staff and amazing office experience from entering the front office to existing. Highly recommended.

Arrogant and Ignorant
Sent here by VA due to anaphylactic issues. Did skin test - said I don't have allergies. Two years later, finally thought to get lab work so send me to urinate in a cup and get blood drawn - suggesting I get up off floor when I pass out again and drive myself to hospital to get lab work. Said in office 'foods don't have histamines' in them - although a simple web search will pull up plenty of MEDICAL JOURNAL articles to the contrary. Not sure if he just didn't want to help me as a patient - or just didn't want to help a veteran and deal with VA insurance. If you have basic allergies, maybe he can help - but anything dealing with possible MCAS or mastocytosis, he won't lift a finger to keep you from an anaphylactic reaction that may end with you waking up dead.

New Patient – Jul 14, 2019

I have been going this Dr for 10 years.. called to make appointment and ran headlong into the authoritarian FRONT DESK.. they refused to recognize me as anything other than a NEW PATIENT. would not schedule an appointment for over 2 months... AND THEN DEMANDED ALL MY insurance information RIGHT NOW.. or else.. so... THE DOCTOR IS GREAT..saved my life. But.. the receptionist and the Nurse are too bent on their POWER over me.. I am finding a new allergist.
