Larkspur, CA |
17 years he's kept me going-- He is well read, stays current He's careful and thoughtful Washes his hands- and does an appropriate hands on physical exam every visit

500 stars were this site to allow it. No nonsense science based treatment. Studies in which he has participated have been published in the highest ranked scholarly journals in the world. My cancer is especially aggressive and there was no approved treatment that offered much hope, so he found a trial for which I qualified, If you want to be treated by a smart, experienced, super well educated, competent, careful doctor, then Dr. Baron offers the best hope there can be.
Mill Valley, CA |
Dr. Baron's insulation from patients can cause them pain. My sweetheart died under Dr. Baron's care. She began treatment with metastatic urothelial cancer, a fatal diagnosis. After two failed rounds of chemo and much suffering she began Tencentriq treatment which had extraordinarily severe side effects. Dr. Baron and his group failed to provide satisfactory monitoring. The intolerable stress caused ulceration that ruptured and emergency surgery failed. Her death was harsh for naught but privacy
