⭐️⭐️⭐️⭐️⭐️ I cannot say enough wonderful things about Dr. Knoble. After being diagnosed with breast cancer, I underwent a double mastectomy followed by reconstructive surgery using tissue from my bikini line. My journey was not simple — I had to return to the OR twice after my mastectomy. At one point, one of my breasts was not taking and had to be removed. I later had a spacer placed and then an implant. Through every setback and every surgery, Dr. Knoble was there. If he couldn’t physically be present, he was on the phone and fully involved. He always knew exactly what was happening with my care. That level of dedication meant everything to me. He consistently made me feel comfortable and at ease. He explained every step in a way I could truly understand, never rushing me and always showing compassion. One moment that really stood out was when he came in on his day off just to talk with me and apologize for not being there during my third OR visit. That kind of care is rare. His team is equally incredible. His PA, Winnie Deng, is amazing — she is attentive, encouraging, and I always leave my appointments feeling uplifted and confident. I highly recommend Dr. Knoble and his entire team. Five stars is not enough.

Dr Knobel is an excellent surgeon who is extremely professional, skilled and compassionate. He performed several difficult surgeries on my nose that was damaged from tumor removal and subsequent radiation therapy. With him I was able to avoid a prosthetic nose. Thank you Dr Knobel!!!! I cannot recommend him enough!

Ethics are not his nature, a terrible experience, worst of the worst.

I found him rude, angry, and very dismissive to my concerns, very complacent. Would never recommend someone with his reckless demeanor.

Dr Knobel and his PA Jessica are amazing and very caring. I'm lucky to have them. They helped me so much with my case and they still do. Having cancer isn't easy but having these doctors by your side, trust me the whole process will be so much easier. God bless them and their team.
