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. Jon Mallen-St. Clair is a brilliant and compassionate surgeon who quite literally saved my life. He removed a 10.1 cm encapsulated cancerous tumor from my face and neck — a procedure so complex that my oncologist described it as “almost impossible.” The tumor was pressing on major facial nerves and extended from my earlobe to my throat. Despite the risks, Dr. St. Clair removed it with extraordinary precision, without spilling cancerous cells into healthy tissue and with zero facial paralysis. He is not only incredibly skilled, with over 300 surgeries to his name, but also one of the kindest and most genuine doctors I’ve ever met. He made me feel calm, cared for, and respected. His warmth, humor, and bedside manner are just as impressive as his surgical talent. If you are facing head or neck surgery, I cannot recommend Dr. St. Clair highly enough. He gave me my life back…. and did it with excellence and heart.Thank you,Melody Valdez

What you’d hope for in a doctor
Dr Jon Mallon-St. Clair is exactly who you’d hope for in a medical scenario. My situation needed decision-making and he immediately put me at ease with his excellent care and calm energy. I wish for more doctors to be trained with his bedside manners—truly noteworthy and I’m grateful for the positive experience.

Dr Mallen-St Clair really sets the high bar for treatment. He's a skilled surgeon who Is truly caring, attentive, thoughtful, and exhibits patience. I came to Dr Mallen-St Clair after visiting another surgeon who did not exhibit these traits. As a patient they are incredibly important , non negotiable traits I require from all of my future caregivers.
