I've been seeing Dr. Chen for about a decade, initially consulting him about a lumbar issue. Since then, as I've grown older I've racked up a host of other pain conditions, too many and complex to enumerate here--and he's helped me navigate every single one. He has helped me with the usual diagnoses and medication prescriptions/management, and also performed lumbar and cervical facet joint and epidural injections, and nerve blocks--office and hospital procedures. What I especially appreciate about him: about my multiple co-existing intersecting pain conditions and diseases, he doesn't compartmentalize, piece-meal, or get myopic--he steps back and see the bigger picture, and somehow appreciates the enormous difficulty living with all this. He 'gets' the dramatic impact of mobility impairment, and was proactive about referring me to a PT and OT, both of which I benefited from. He's very thorough, super competent and experienced, deeply invested in treatment outcome, with rich expertise. Every single procedure I've done with him has been successful with zero complications. There are many physicians out there, and I've gone around that medical block, been the object of authoritarian ego-ridden physicians' accusations of malingering and the rest. Dr. Chen is the opposite. He is remarkably open and without ego, very warm and caring. Every single office visit I know that I'll be able to go over my concerns and needs, know that he'll genuinely listen and come up with a plan of action, a strategy which will give me hope. In my world of relentless chronic pain, hope is my only currency. I live on hope--and he intuits this with ease. He never goes through the motions, never phones it in. He shows up with his whole-hearted gentle presence and kind heart. He is empathetic and understanding, unfailingly sensitive. He's unusually humble and open to my input, e.g. when I come in with an idea for an off label med, he's willing to try it. I also appreciate that he knows and trusts me and my intentions, e.g. doesn't automatically put me in the bin of a "drug-seeking" patient, as doctors have default done in the past. He seems to get that I was that nerdy, squeaky clean high school kid. When I first began to see him, I had only two medical conditions, and was consulting with him for one of them. My health issues have increased in chronicity and severity, and he has never once made me feel as if if was becoming too much for him to deal with, never once intimated that he was overwhelmed with my complexity ... and though I've become exhausted, he has been the epitome of professional aplomb. Btw., he has a penchant for educating the patient, e.g. whenever I see him, for whatever condition, he'll show me my MRI, X-ray, or model of the spine ... and explain in infinitesimal detail whatever's wrong with me. It's important to him that I understand what it is that's going on, what procedure he's about to do, the mechanics and process of it. Frankly, at this point, I humor him and listen ... because I'm so exhausted and overwhelmed, I no longer care about the details--my attitude is, "please, just fix me already" :-) I also have difficulty visualizing three dimensional space and forget the medical jargon. But I do appreciate his efforts to explain, and after all these years, I do think some of it has sunk in, lol. His communique is excellent, e.g. every time I've emailed him with a question or concern (sometimes from out of the country), he responded in a timely fashion. About scheduling, because he's in high demand, it's hard to get a quick appointment; I schedule months in advance. But this is something I've come to accept, because I know it will be worth my while to wait and when I do go into see him, he will not be rushed and try to get me out of there in 10 minutes. He actively engages--this is sadly uncommon in medicine these days. He actually listens and bases his response on what I say--he takes in data I give and composes a suitable strategy on the input his getting. What a concept, huh? This is something I feel like celebrating, because it feels so great :-) His assistant, Adriana, I also love: she's warm, caring, and solicitous, on the ball and always efficiently scheduling surgeries. She's been working with him for many years and knows his process--they make a terrific team, and I'm thrilled that she migrated with him after he moved from his private practice in San Mateo. They're now at Mills in Burlingame, where there's tons of free parking conveniently in front of the clinic (you don't need parking validation). The hospital/clinic follows the usual COVID protocols of checking temperatures, requiring hand sanitizer, and fresh masks. If I could give six stars here: I lucked out when I first stepped into his office. I'm beyond grateful and thankful I get to be a patient of his. Dr. Felix Chen is a rare quality human being where he gives much of himself, and the planet is a better place for him existing.
