Thomas Tseng, DO, MPH

i use to see Dr Tseng infrequently. I think he is actually a good doctor and is very nice but the biggest problem is the wait time. If they would fix that problem i definitely would go back and see him. 90mins to 2 hours is just a ridiculous time to wait.

worse doctor ever, I had stomach pain for almost a year, he had change 4 different medication and drawn numerous blood. cant find out my true symptoms. also send me to do ultra sound and endoscopy (cost me thousands of dollar) still cant find out my symptoms. after a full long year of pain I decide to part away with this so call him self a doctor.
After the switch, a simple blood test from my new doctor, he found bacteria in my stomach with some simple antibiotics my symptom is cure.
please think twice before any one out there pay this guy a visit

Great doctor who is very tuned into the wellbeing of his patients. DO’s have a holistic approach when treating patients so they take into account how your body functions as a whole.
Dr. Tseng is also very professional and caring towards his patients, so you can rest assured that you’re in good hands.

Love love my doctor!!! After 3 years coming here I must say this is an amazing very professional office! The staff are super friendly and my dr, is the best ever! He takes his time with you and makes sure you are taking care of your self! Will come here forever!

He is a pretty good in diagnosing the problem but does not seem to care too much about patient’s time. I have been coming here for over 10 years. Have not been here for at least 3 years. Thank goodness I have been healthy. I am taking an oath to make this my last visit. Each visit regardless with or without appointment is 90 minutes to 120 minutes. Just ridiculous!!! Other than Katherine, most staffs are either rude or does not know what they are doing. My appointment was 12:25, when I walked in, all 13 chairs in the lobby was filled up. The 14^th person was on a wheel chair. I was the 15^th person and would just have to stand around.
The other thing is the blood test is extremely high here. I get my thyroid blood test here and cost over $ 200.00 with insurance. With the same insurance, I get the same thyroid test with Dr. James Hennenburg in Pasadena (10 Congress is the address), cost around $ 25.00. I would not recommend this doctor unless he changes his scheduling policy and not over book patients and ask for all testing prices before you let them test you.

PLEASE… this place needs to review the way they run their office. It appears they’re more concerned with booking as many patients as possible than to provide quality service.
So many people have complained of waiting 60 – 90 minutes, it’s unbelievable! How can you do business like that?!! My mother has been waiting to see him for longer than that. Her appointment was at 3pm, she was here 10 mins before, and she’s still waiting as I type this (It’s 4:52pm).
Why even have appointments?!
I hope more people see these reviews so he keeps losing patients, and potential ones avoid him.

not a place for regular seeing doctor. Because they doing so slow and they accept walk-​ins as same with appointments. So If you have things to do later don’t see him.

Dr Tseng is nice, he has many patients, but the biggest problem is although u have an appointment, u still need to wait for a long time. I think appointment doesn’t work here. Every time when I come to the office, I need to spend at least 90mins to wait. Even though I am the first patient to the office in the morning, I also need to wait at least 30 mins then I can see him. Hope his office staff can see the review and improve their business.

The doctor is really nice and respectful but I think it shows that he doesn’t run his office well because I always have to wait over an hour from my appointment time to see him. I’m wasting my time just sitting I a room. Don’t take walk ins or don’t book so many appointments together if you can’t handle it and make your patients wait so long. It’s ridiculous to wait over 1 hour. I can take 30 minutes, but everyone has places to be and things to do. I came in early from my appointment time, did a few test for my vitals, sat in an exam room for 90 minutes before finally having the doctor come in.

I am very skeptical of doctors these days. My grandfather was an East Coast country doctor who would make house calls 24 hours a day if needed — toting his trusty alligator skin bag.
I was pleased to discover that Dr. Tseng channels the «old school» spirit of a *real* doctor. From the pleasant but goal-​oriented banter to the expert and not off-​putting poking and prodding, Dr. Tseng comported himself with not only true professionalism (which would be enough in itself), but also a genuine sense that he cares about his patients. Glad I found this place.
I should note that I am VERY (Mayflower) white — at no point did I sense any racism or xenophobia from the staff (I get a lot in Monterey Park) — they spoke in perfect English and were very helpful and friendly.

I don’t recommend this doctor at all… I went there yesterday cause I got the bad cold his words not mine. I asked for a shot. he said no.. cause I don’t need it. the next day I got even worst. .I called the office.. He said. .all he can do is medicine. …wtf…they don’t do shots their.. and I have to pay another copayment screw this guy. … go somewhere else

Dr. Tseng is one of the most quality physicians you will come across. I’ve been a patient under him for over a decade. He is one of those doctors that will take the time to talk to you like a person. There were a few times where I was worried about a symptom which I had doubts on and he has an ability to calm you down and explain what it is. Fortunately, he put my worries and anxiety aside. The staff is extremely friendly and helpful as well to make you feel at ease. I definitely recommend this place.

Thank you again Unilocal for leading me to Dr. Tseng.
The first thing he asked me was «How did you find me?» Well, as stalkerish as today’s society is, it has its perks. Dr. Tseng is as genuine as they say –the office is clean, equipment is well-​maintained, and my problem was resolved.
The wait is insane, I know. either try to be the first in line or last!

The doctor is great, the price isn’t to bad but don’t bother making a appointment. You’ll still end up waiting FOREVER. Had a 10:30 appointment and didn’t get to see the doctor till 12pm.

great doctor and reasonable charge if you don’t have insurance.
long wait though. try to schedule as close to before they close is the key so you don’t have to wait too long.

Dr. Tseng has been keeping it real before real even existed… no lie!
My family and I started to come here when we moved back to LA. In the past, I never really knew what a good doctor entailed. I found out what constituted as a good doctor when I got to college and used the student health clinic. There, they know the true meaning of serving patients and making sure their needs are met.
Anyways, back to my story. Since graduating from college, I have been buying my own health insurance (independent women, throw your hands up at me). I decided to try Dr. Tseng due to my mom’s accolades for this man. And, lesson learned, always listen to your mama!
I scheduled a yearly exam via my trusty health insurance and they secured me to be the first patient on a Friday morning… nice! When I got there, I was one of the first ones to arrive, but they still let the regular patients in first (understandable because they need to clear with my health insurance first). When it got to my turn (25 minute wait), the nurse that checked my height and my weight measured it wrong, so I had to do it all over again at the end of my checkup. The nurse who helped me test all my other stuff (glucose levels, flexibility, blood pressure, etc) was super nice and informative. I liked how she was friendly and efficient so I could go back to work quick.
Dr. Tseng was personable and pleasant in helping me plan a healthy way to lose weight (lost 21 lbs and counting!). He also gave me tips and suggested a followup check up. The rooms here are also very spacious and very very clean. Also like that they have a vast array of magazines for you to peruse during those long waits. Parking is sometimes hard to find because there are alot of patients for the other clinics and the hospital next door.
Overall, hate the (understandable) long waits but love the service I get! Definitely will be coming back here for years to come!

Dr. Tseng… where should I start…
I had some bug bites that turned into staph/​MRSA infections and after finding out my previous doctor in LA disappeared I had to Unilocal a new doctor and here I found Dr. Tseng!
I read the 1 star review from the previous Unilocaler and had my reservations especially since my 4^th year med school girlfriend accompanied me, we were really just there for a prescription that she can’t write. After we met him, he is the most affable and natural doctor I’ve ever met. He’s not imposing or condescending like some doctors I’ve experienced or force feeding a generic advice to rush on to the next patient. The doctors I experience come in, barely look at you, read your file, suggest something real quick and before you know it they’re gone. Dr. Tseng takes a seat…
In regards to the comment prior about the doctor disagreeing, my gf and I discussed this, and our personal opinions (disclaimer) are that he’s a doctor! Doctors have to make informed decisions, and sometimes we don’t like to hear what they may have to say. It’s part of the profession. I mean, my gf didn’t quite understand why he prescribed the way he did (granted she’s only a student) but in the end, everything he did made perfect sense.
The office is very clean and organized, but the wait stories are true. Every time I’ve visited there, I’ve had to wait 30 – 45 minutes even with an appointment. BUT… he really takes the time with his patients. He’s never on the edge of his seat like he wants to hustle you away so he can bank on the next patient. He doesn’t talk fast like answering your questions are trivial. He just calmly sits there until you feel assured you have every question you have answered for this visit. He speaks to you like a patient, and not like a child. SO, at the end of the day, I never mind waiting for him.
I’ve visited him probably 4 – 5 times now (proudly the Duke of this doctor’s office!) and it’s been the same experience every time.
If you’re the type of person who wants to get in and out of a doctor’s office and hear what you want to hear just to get a prescription, this is not the doctor for you. If you’re patient and truly takes the advice of the doctor, he’s your guy.
Cheers,
Sean

THE +‘s: doc tseng and his crew are super detailed and attentive. they never rush you through any procedure or appointment and always listen to what you say. excellent follow-​up on test results and the like. the office and lab rooms are super-​clean and surprisingly well decorated (elegant) for a doctor’s office. they accept most insurances.
THE -‘s: even with an appointment, you still end up waiting for 20 minutes on average. possibly due to the aforementioned detailed attention from the doc and his staff.
SUM: for several years i was without a go-​to doc since my last one moved away. then, when i went to another doc from a friend’s recommendation due to a car accident, this other doc was instantly hands-​off thinking all i wanted was a report so i can collect insurance money. wtf?! so, i went to doc tseng on a co-worker’s recommendation. first question from doc tseng was how i was feeling, not «which auto insurance company do you have?». i’ve been the doc’s fan from that moment on. i don’t care that i have to wait to see him, he and his staff are worth the wait because they take care of me.

I would NOT recommend this doctor for various reasons.
He is nice until you disagree with him. He does not respect his patient’s opinions or feelings. Once you disagree with him, he can care less about you.
I don’t want anyone to go through what my family is going through right now.
I will wait until we find a new doctor for our family member before I write more details, since that patient is still under his care.

I’ve known Dr. Tseng longer than I have known most of my friends in L.A. In the eleven years since I first met him, I’ve had multiple changes in careers, relationships, homes and my health, but throughout it all he has been a constant. He probably knows me better than most of my co-​workers and I only see Dr. Tseng for 10 minutes every couple months.
His entire staff is friendly and though most speak Chinese as their primary language, English has never been a problem with him or the team. A year ago or so, the office moved to a new location which means the office is nice and modern.
The place does get busy sometimes, however, the team always finds a way to get patients taken care of as quickly as possible while maintaining professionalism and friendliness. Today was quick though.
I’ve moved again and may actually have to switch to another doctor. A big part of me doesn’t want to change because it feels like losing a trusted friend.
