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. Kalil probably saved my life; guardian angel
It is not an overstatement to say that Dr. Kalil probably saved my life. I was diagnosed with metasticized prostate cancer four months ago. Dr. Kalil immediately prescribed an extremely effective cocktail of oral medications, with mild chemotherapy layered in. IT WORKED!! My PSA count dropped precipitously, from over 6,000 to 2.6 in the latest reading. O.M.G.I also had prostate cancer-related blood clotting that went to my lungs at one point, sending me to the ER (prompting initial visit to Dr. Kalil), also completely eliminated through meds prescribed by Dr. Kalil. Throughout the process, behind the scenes, Dr. Kalil has coordinated all testing, insurance approvals, etc. with both service providers and Aetna, so that I never had to worry, or had any important medical test or medication refused or was overcharged. On an interpersonal level, Dr. Kalil exudes compassion, combined with a kind of European cool, without an accent, but most importantly, relentless competence.FANTASTIC!

I would highly recommend Dr. Kalil to anyone in need of the services of an oncologist. He explained thoroughly what my husband was undergoing and what to expect after he was diagnosed. He answered all my concerns and questions. His staff is very friendly and accommodating. Scheduling for an appointment was easy. My husband has now recovered, thanks to Dr. Kalil.

The doctor is nice but staff is very uncaring. One calls to leave an urgent a message to the doctor and you have to leave a message which they don't return .They actually don't care about the patients and they are very rude.

Dr. Kalil is truly a wonderful doctor, knowledgeable, professional and caring. He serves his patients' interests first and foremost, as anyone who has taken the Hippocratic oath should do. He took the best care of my friend after a stroke, answered all our questions in a most courteous and professional manner. He takes time with the patient. His evaluation andrecommendations were excellent. Having been to so many doctors lately, Dr. Kalil left us with the absolute best impression.

Dr. Kalil is truly FOR the patient. I don't think it's easy for doctors to advocate for what is in their patients' best interest anymore, but Dr. Kalil is one of the FINEST patient advocates I have EVER had the privilege of meeting and working with.

Wonderful doctor. Spends time with you and answers all your questions. He runs behind schedule because he gives everyone individual attention. No rushing to get you in and out.
