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.

Regrettably during my scheduled appointment I politely asked PA to tell Dr Byeff that I couldn’t wait any longer and can he please call me if any changes in treatment is necessary, well,,,,Dr Byeff did not know I was in one of his waiting rooms already clearly hearing him voice his opinion w/ scheduling staff to be disturbing on many levels,,,, in fact so bad that a voice recording immediately took place,,, without question his ethics to practice is in order,,, distrust is another word that comes to mind,,,, regrettably all this took place,,,during my 45 minute stay,, finding a new doctor,,,, without question,,, Shame on you doctor,,,,, SMH ?????,,,,,, soap and water was once used for poddy mouth,,,,

The best Hematologist & Oncologist on the planet!!

Was referred to Dr. Byeff for blood and his keen eye & knowledge of testing found a "LEFT UPPER LUNG MASS"! Had first of treatment plan today with a GREAT TEAM Dr. Byeff referred & assembled. My norm is, if in a vehicle, "I'll do all the driving", however, 'IN THIS CASE' I feel more comfortable in the back seat with Dr. Byeff behind the wheel and his staff belongs on TV they are SO good! Carry on, Dr. Byeff! (H Lenkiewicz) 12/28/21

I have been a patient of Dr. Byeff's for over five years, visiting the Southington office on a quarterly basis. Having any sort of chronic condition is unfortunate but Dr. Byeff's knowledge, expertise and compassion has been invaluable helping monitor my condition and alleviating some of the associated stress and anxiety. I have great confidence in his abilities and hope that he does not ever retire.
