    I've been coming to Dr. Thomas Tseng for over 20 years. Him and his staff (Catherine, Donna, and others) who have known me since I was a child, have always been kind and given me great care and service every visit. They opened a new facility back in September and their space is much bigger and the interior looks amazing. They hired more staff and my wait time was short. On my most recent visit, Dr. Tseng was not available, however there was a new PA (I forgot her name, im sorry!) and she was very professional, knowledgeable, and patient. She answered all of my questions with very detailed answers. I would definitely recommend her if you have any issues and coming to Dr. Thomas Tseng for all your medical needs!

    Here is Dr. Thomas information. Everything you need for your next appointment!

    Dr. Tseng is thorough and attentive and is a great primary care and family medicine doctor. Blood work is next door, which makes things a lot easier than going to another place. He recently moved and built this beautiful new office. Parking is easy and the staff is wonderful. They are fluent in Cantonese, Mandarin, Taiwanese and Spanish, if needed. Ps. I'll leave a little surprise there for you when you get weighed in.

    I have been Dr. Tsengs  patient for 2 years now and all I gotta say is he is the best doctor ever, very friendly and kind.

    Dr. Thomas Tseng is the best! Very friendly staff! And I love that they care about patients.

    The staff, nurses, PA Jamie & Dr Thomas are so amazing! Helped me with so many health conditions since around 2016 ! The upgraded office is amazing. They care a lot about their patients & creating a welcoming vibe. I got my urinary frequency, hyperthyroidism taken care of/ referrered to specialists thanks to dr tseng. I am so thankful for the detailed care i receive everytime i come!

    Can you draw blood onsite for lab tests or do we need to go off site to a lab in order to draw blood?

    Hi Ben! We have a lab located in the same plaza that we are in, right next door to us. They are available the same schedule/hours as our office and can assist our patients for all their testing needs. Hope this information helps, have a great day!

If you are looking for a clinic that is NOT crowded at ALL, when you are on time for your appointment and THEY ARE ON TIME too, here's your best choice. when you push open the door, and you see an empty waiting room, don't doubt yourself, you are at the right place, this is their way to ensure their high quality of caring for their patients. If you are looking for a clinic WITHOUT a grumpy face reception/front desk lady, it's time for you to call and make your appointment with them, Jessica is very helpful and willing to work with you to figure out all your insurance. Their staffs are the most nice, friendly and kind crew that I've never experience else where. (I've tried 4 different family doctors before I found Dr.Lee, it's been yearssss now, I still feel it is my luck to found and be able to build an long term or even life time relationship with this clinic.) P.s. and I forgot to mention, they have their own physical therapist in the house, mm hmm I know, that's awesome!!

When i inquired about it, the front desk person told me she didn't have me down for physical. I asked what did she have me down for? And it was a physical. So then asked if there was any other medical needs or questions i needed to ask the doctor today? and when i said no, she refunded me my copay. A week later, someone from their office called me and asked me to come in so i can discuss my blood results with a doctor. They also gave me the option to do this over the phone and SURPRISE!!!! THEY WANTED TO CHARGE ME ANOTHER COPAY!!!! At my old PCP, they did not charge me a second copay for discussing my results. if you don't want to be nickeled and dimed for everything, then i suggest you look for another doctor's office. But i would say the doctor's here are actually very nice. They do listen to your concerns and i did not feel rushed during my appointment.

    Dr. David Seto is truly a rare find. He's not only a board-certified medical doctor and osteopathic…read morephysician, but also a highly skilled acupuncturist. He currently practices at the VA Hospital, which speaks volumes about his deep commitment to healing and serving patients like me...people who have spent years visiting countless doctors and specialists in search of real answers and lasting relief. After so many frustrating experiences, finding Dr. Seto honestly felt like hitting the jackpot... and I don't say that lightly. He is kind, compassionate, humble, and extraordinarily gifted at what he does. Despite his impressive academic background, he carries himself with genuine warmth and humility. His credentials are exceptional: Princeton University for his undergraduate degree (on scholarship), New Jersey Medical School for his medical doctorate (also on full scholarship, graduating with Alpha Omega Alpha honors), followed by residency in Internal Medicine at Weill Cornell Medical College of Cornell University. He's board-certified by the American Board of Internal Medicine. What truly sets him apart is his dedication to integrating Eastern and Western medicine. After his formal training in the U.S., he lived in Beijing, China (2013-2015), where he apprenticed under Dr. Wang Ju-Yi, a pioneer in classical Chinese acupuncture. He has accumulated thousands of hours of advanced clinical training in acupuncture and osteopathic manipulation, and is a member of several prestigious organizations including the American Academy of Osteopathy and the American Academy of Medical Acupuncture. During my first visit, what stood out was how thorough and thoughtful his intake process was. He took the time to ask deep, meaningful questions about my history to uncover the root cause of my issues, something no other doctor had done before. He discovered a long-standing blockage in my system and addressed it using a powerful combination of osteopathic manipulation and acupuncture. After just one session, I felt a remarkable difference throughout my entire body. This is not an exaggeration. Unlike the rushed, impersonal experiences I've had with many Western doctors, Dr. Seto devoted over four hours to my initial appointment, determined to understand my condition from every angle. It was the most comprehensive, patient-centered experience I've ever had. I also want to mention Yvonne, his incredible office manager, who was kind, patient, and thorough in explaining everything before my appointment. She made me feel completely at ease. At 65, after years of bouncing from one specialist to another, I finally feel like I've found the doctor I've been searching for. This was my first time experiencing the combination of osteopathic manipulation and acupuncture, and though I had some doubts initially, I'm so grateful I kept an open mind. If there's a wait to see Dr. David Seto, let me assure you... he is absolutely worth the wait.

    Hands down one of the best at what he does. I've been going for a few years now and I'm always…read moreimpressed by the doctors knowledge and know how. Not to mention this stuff really works. He keeps things simple and he's just as cool as he is informed & professional.

I often saw his wife, the receptionist, giving gifts to the child patients. However, like another person mentioned, there's a side to Dr. Tsai and his wife, Susan, that comes out whenever there is a deviation from this tightly controlled environment. In my case, the osteopath that Dr. Tsai was co-treating with was out of town and unable to help me when a molar got loose due to the dental treatment that the other osteopath was supervising. Dr. Tsai felt how loose the tooth was but refused to cover for the absent osteopath. He said I would be safe if it only lasted "up to two weeks." At three weeks, the tooth was on the brink of falling out, but the appliance was still in while we waited for the return of the other osteopath. Again, he had the option of helping me fix the appliance (at the dentist's) that week. He not only refused but this told me that it was okay to have this tooth getting looser for "up to three weeks." When I asked him to clarify, because last week, at two weeks, he had said "two weeks," he argued with me, insisting that three weeks was okay. Then he asked Susan when the other osteopath would be coming back to town. "Next week," she said, and he ran his hand through his hair in irritation and then walked away. That molar was so damaged it is now a source of endless problems and has made any further orthopedic or orthodontic interventions next to impossible. It literally would have taken him five minutes to help save that tooth, and by extension, my jaw. To watch him walk away from something so simple, easy, and ethical profoundly shocked me. I guess he was afraid of stepping on the other doctor's toes, but this was an emergency. To be gaslit, told that I had misunderstood the first (accurate prognosis), simply because he refused to help was highly unethical traumatic. To make matters worse, Susan became very rude to me after this.

    I have the unfortunate status of having seen DOZENS (this is not an exaggeration) of health care…read morepractitioners for a chronic condition. Another non exaggeration is that Dr. Tsai has been far and away the most impactful at actually *resolving* what is going on. I cannot wrap my head around how he works but for me, the very tangible proof is in the pudding. I was fairly debilitated before and have slowly gained SO much functioning back. His work has even given me the gift of being well enough physically to consider having children (which was off the table before due to my being so symptomatic). Dr. Tsai is truly a gift and I feel blessed beyond compare to have encountered him. Also he's an absolute darling: sweet, kind, brilliant, genuine, and so relatable. Don't let his quiet exterior fool you. ;) Caution: contrary to what we are led to believe, there is usually no quick fix for things. I've dealt with this problem for so many years so it has taken time to resolve. The patient needs to have both a positive attitude about the ability to heal (there is substantial psychological research to support this), the patience to let the body rest and recoup after treatments, and the patience to respect your body's process. For reference, my problem is/was primarily a neurological one. I know OMT usually deals mostly with physical issues, making my insane improvement all the more remarkable. I had issue with my vision, balance, and sensory integration. You also cannot imagine how great it felt to have a doctor sit down and show me on a physical and graphic model of the brain what the heck was happening inside. So many other clinicians dismissed me since they were not educated enough to understand my situation

We can contact her through phone or email anytime and she is extremely responsive. She also proactively advocates for her patients' rights and takes the time to explain in thorough detail complex diagnoses. When my relative underwent an intensive surgical procedure, Dr. Wong was available every step of the long procedure and long recovery period to answer questions on side effects, adjust medication, and prescribe additional medication when appropriate. Dr. Wong also communicated and interfaced with the other doctors/ specialists to advocate on behalf of her patient during a stressful period of time so that the patient could focus on recovery. Finally, Dr. Wong administers medical care with unfaltering precision and a holistic consideration of the patient's entire medical background. Her advice and diagnoses demonstrate that she deeply understands her patient's medical history, current ailments, and what treatment is most effective and appropriate for this particular individual patient. My family is very grateful to Dr. Wong and her excellent practice!
