He had been my primary care doctor for a while, but never really thought he was great. He was more a "meh, i'll find something better but i'm busy right now and he has a free schedule." Until this last web interview took it too far. I told him something personal that I really needed with my health. And yeah it wasn't even a benzo or anything on that level. He mocked my situation. Literally laughed in my face and said either my plan or you'll probably die. I said "there's nothing you can do for me at all?". He said "nope." So i said "thanks you're just wasting my time, i need to get back to work." Don't waste your time or insurance on this guy read more

I started with Dr. Yen, February 2018. In the beginning, I felt he was good. Usually, I pick female doctors, but I figured, nowadays, doctors barely touch you. I came in with all my medical records from Kaiser. What I don't like about Dr. Yen. He doesn't like to call in any medications without you coming in. He doesn't like Email or phone diagnosis. When I came to Dr. Yen he knew I needed sinus surgery. So, I get frequent sinus infections. So, what's the big deal. I SHOULD be able to call or email you for the medications. It's not like it's a narcotic. Secondly, I asked for a referral, he wants to see me first. Why? I told you I had an issue when I first came to him, so it was already discussed. Basically, he and others said there is nothing that can help it. Well, I want to see someone. So, I have to see you for that, pay a copay for something I already discussed with you. Doesn't make sense. Third, when I started with Dr. Yen, I was made to feel that a medication, that I have been taking for YEARS, he felt was addicting. Okay, well, everyone is not an opoid or drug addicted person. He almost changed my medication. I felt like he was implying that I could become addicted. Basically, I told him, the particular medication was just down to a few pills and he could call Kaiser and ask when it was filled. He would find that I got it almost a year ago. So, with that, Im sure that would prove, I ain't misusing my pills. I don't like to be put in that group. Some of us actually only take what we need. If you ask for a referral, he wants to see you EVERY TIME. I complained about a lump under my arm, he had to see me first. Even though for the most part, I like United Healthcare, there is much that needs improvement on their part. The email system is terrible, no video appointments, oh sorry, they prefer you not go to ER, instead use the app for video appointments, but it cost you $50. Their website for patients sucks. I will give it to Kaiser, overall they are state of the art. I'm presently looking to change to a female doctor that is on the same page with me. I'm looking for someone younger. Someone with a better bedside manner. read more

He is condescending and indifferent. Not what you would expect from a health care professional. I'm extremely disappointed.

I wish I had seen those reviews before my appointment. I have been to Jerry Yen's office today regarding some stomach pains. He spoke to me for less than 5 min (I had more time to talk more to his nurse, than to himself). The consultation was awful, I couldn't explain anything, he was giving me the impression he was too busy doing something else better than talking to me and trying to understand my problems. He gave me a sample medicine that was for acid pains, even though I told him I don't have any acid pains, only sharp pain. Horrible consultation, horrible doctor. Feel very disappointed now that I went there and he's done nothing to help me. Ended up paying a $20 copay (ok, not the end of the world, but I feel that this $20 is a lot more, since I still have the pain, and was treated as I shouldn't be). read more

I've been in search of a primary Dr for over two years. I finally came across Dr. Yen. He was attentive and even picked up on my subtle rise in blood pressure. He inquired more about my history with my blood pressure changes and ordered an EKG and a series of blood tests. Instead of being dismissive he scheduled me to come back in three months to check on it again. Finally!! I felt like I was listen to and treated with concern of something that could potential he be something or nothing. Finally I feel like I found my doctor. read more

I would give the man 10 stars. He is exceptional. He is brilliant. He especially cares about his patients and their care is paramount. When you are in his care you needn't worry about a thing he pays attention to every detail and you can be assured you are getting the best care bar none. I have been a patient for many years and he has never failed me. I am a doctor's nightmare. I ask questions, want copies of everything, dig deep for expert answers, expect them to be available to me and am not afraid to voice my opinion on service or anything else. This can be disconcerting for even the most capable and patient doctor. but he is so patient oriented that he never fails to fulfill my expectations. read more

I usually see a different doctor in this practice but she was busy and I was in need of an appointment ASAP. I get bouts of MRSA from time to time and needed a possible infection checked out immediately. Once inside of the doctor's office he made it seem as if I were wasting his time and did not provide any useful information or advice, he even contradicted what my regular doctor has previously told me about dealing with MSRA. It was only after my 3rd request did he finally take a culture to send off to the lab. And as for the comments made below by another patient about how he forgets to call with lab results, he actually advised me before the end of the visit that I would need to call the office myself to get the lab results because he tends to forget to call his patients. After expressing to him how disheartening that was to hear I left his office feeling very unsure about my condition and the care I had just received. Surprisingly enough I did receive a phone call from the doctor's office a few day later, but his report of the results would have consisted of maybe 5 words had I not asked several times for a further explain of the results and findings. It was like "pulling teeth" to get any information from this man and to top it all off I felt I received condescending attitudes from him during both the appointment and the follow up call. I would rather pay Emergency Room visit prices than to ever see this doctor again. read more

Called Valley Care to setup a appointment with any available Doctor who was able to see me that same day. And lucky me I got Jerry Yen. I made the appointment for a earache and some massive back pain that started that morning. When making the appointment I let the person on the phone know as well as the nurse that checks your blood pressure that I was there for ear and back pain. When I was greeted by Dr. Yen the first thing he asked was why i was there. I told him "ear and back pain". Dr Yen let out a giant sigh and barked "No, one said anything about back pain!". He then asked me if I took anything for my back. I replied "Not really just Ibuprofen" his response was "WELL THAT'S SOMETHING". I couldn't believe how rude this guy was. He then kind of proceeded to rush me out of there. I asked for a referral for a back specialist and he wrote down the information. Turns out he gave me the number for a ear, nose and throat specialist. *sigh* I've had bad Doctors even ones that barley say or do anything. This guy is by far the worst. I regret paying the co-pay and any fees that hit my insurance. What a complete waste of time. read more

Dr. Yen epitomizes what is wrong with health care in US & not only that he is greed personified. I had scheduled an appointment (since my primary care doc was out of town) with this office to get my pink eye looked at however I had to go to urgent care as before the appointment date it became worse. This greedy quack billed me for no show & even after I explained that I had to go to urgent care didn't budge. I also reminded him that when I had scheduled the appointment his office did not tell me that if I don't call in I will be billed. Stay far far away from this hack. I will also call Valley Care as they shouldn't let doctors like him be associated with their name. read more

If I could give him no stars I would!! Usually it will take me weeks or months to add a review, but he was so bad that I'm posting this review right after coming out of my 3 min appointment!! I have never met a doctor that could care less about his patients. He walks in the room, doesn't close the door, and asked why I was there. Told him it was for an ear infection. He looks in my ear and jams the otoscope right in my ear. I push away because I'm in terrible pain. He backs away and rolls his eyes like he's annoyed! I tell him it hurts so he looks again. Jams the otoscope back in there and twirls it around!! I'm closing my eyes and holding in the pain and repeat to him that he's hurting me!! He tells me something quick. I swear to you that I was only in there for 3 mins. It's taking me longer to type this review!! I feel this doctor is only here to see as many patients he can see in a day for the money. He does not care about you at all. Save your money and go somewhere else. It was a wasted copay for me and I feel sorry for the insurance company that has to pay the rest because his service wasn't even worth it!! read more

I've been at this practice for several years now and while the doctors may be okay, not great but just okay, the waits are typically very long (30 -45 minutes late on average) and the reception desk folks are absolutely the rudest people I've ever met. Dr. Yen specifically is not very useful...he'll do what you want him to do (e.g. write a scrip) but is not inquisitive, insightful or proactive. One example of many, i had standard blood tests done for cholesterol, blood sugars, etc...but the Dr never called me with results. When I called to inquire I was told that he would have called had anything been wrong. My hunch is that he never even looked at them. I would not recommend this doctor or this practice to anyone! read more

Dr. Yen is a knowledgeable and skilled primary care physician. He has been my doc for 22 years. During that time, he has shown himself to be an excellent diagnostician. He accurately diagnosed several fairly rare conditions for me during physical examinations. He is easily accessible and has access to a large local network of specialty and subspecialty physicians. His referrals for lab and imaging services are sensitive to the patient's need for economical and well as high quality providers. read more

I truly hate this Doctor. I've seen him 1x about 16 yrs ago when he took over some of Doctor Panginiban's patients (who also wasn't that great) I'll never forget that 1st impression I got of him as a M.D. I went in because I couldn't get over a terrible cold...instead of prescribing me anything he asked 1st if I've tried over the counter medication, and had this look on his face like wtf you want me to do about it?!! I then said, but can't you prescribe me any antibiotics, or something...keep in mind I probably was only 16 then, and under parents insurance. Oh then I had to see him 1x after that, because my mom kept him as a physician, and at that time I had a newborn baby, and needed to take my mom to her appointment. Well my newborn at the time was being fussy, and crying. He mentioned after the appointment, next time to leave the baby at home...exactly in those words..What a jerk! Can't believe he's still around...Don't go to him if you're looking for a friendly family physician. read more

Dr Yee is hands down the best doctor that I have ever met. Caring, knowledgeable and communicative. If you are looking for a doctor and have the opportunity to choose Dr Yee, you won't be sorry! read more

I am very happy with Dr. Yen. You can almost always get an appointment the same day you phone for one which is very helpful when a family member is ill. We came to Dr Yen on a recommendation of a friend whose very ill family member had been in his care. read more

If you truly care about your health, stay away from this doctor. I had been seeing him for several years just for usual things like yearly physicals, colds etc. Several months ago I saw a different doctor for a separate issue. That doctor ordered a typical blood test, but in addition, checked for my PSA level (Prostate). Well after receiving my lab report, the doctor was rather alarmed that my PSA was well beyond what is considered normal. I went back to Dr. Yen only to find out that through the years, he had never ordered a PSA test! He told me during my last visit with him, that he typically does not order PSA tests, since they often produce "false positive" results. Of course the test isn't perfect, but it does serve as an indicator of possible prostate cancer, and subsequent tests can always be ordered to determine if there is a trend of rising PSA levels. This blood test is currently the primary means through which prostate cancer is screened. Unfortunately for me, no historic information was available since he never ordered the test! He then said, well now I have to refer you to a urologist. Of course by this time, I didn't trust any referral from him, so instead I did my own research and found a top notch urologist in Concord. During my first visit, he quickly detected a bump on the side of my prostate. After a series of tests including a biopsy, it was determined that all four sample cores were positive for cancer. I was given a Gleason score of 7, which falls somewhere in the middle of severity for this type of cancer. As of this writing, I am now recovering from a radical prostatectomy and have received a pathology report that indicates the cancer has not spread. Luckily for me, the cancer was confined to the prostate itself. Had I continued to see Dr. Yen for several more years, and his failure to test my PSA level, the cancer would likely have spread, after which the prognosis is rather grim. Typically patients with prostate cancer that has spread, are only given five years or so to live. Thank God I decided to see this new, much more responsible doctor, who quite possibly saved my life, just by ordering this simple blood test. By the way, I am a young 55 year old, with hopefully many more years to live. To summarize, if you really care about your health, do not place your trust in Dr. Yen! read more
