Would recommend Dr. Yang to any of my friends! He is a great vet and made us feel comfortable and confident when getting surgery for our puppy with a complicated medical history. Alicia and the rest of the office staff were great to work with as well! Thanks!

We take our precious Shetland Sheepdog there, as we did her predecessor. There are quire literally no words we could say about Dr. Carlos Yang that more clearly demonstrates our faith in him and his practice.

Dr. Yang and the team are quick to help and they really care about your pets. They have provided our cats with good care for a few years now and Dr. Yang always calls to follow up or answer questions. My husband and I rescued a litter of five sick kittens and they were able to fit us in so they had the care and meds they needed right away. Foster fail, we are keeping two of them:). We love Thornhill Pet Hospital!

I love Thornhill Pet Hospital! Dr. Yang is very nice and knows what he’s doing, great vet! He has helped my furry babies with a lot especially my senior dog when he got a herniated disc twice. My little guy is aggressive and Dr. Yang is kind and gentle towards my little monster. His wife, Alicia is super nice as well! The staff that I’ve met is very kind and professional as well. Overall I am very happy with them and have been going to Dr. Yang for almost a decade now.
Highly recommended!

We are 100% satisfied with the experience that we've received. Thornhill always goes above and beyond to address and care for the needs of my sick pets. We've been with them for many, many years and I must admit, I always left content, knowing my furbabies received the best care. And they always get better with Dr. Yang's precise diagnosis. Thank you Thornhill Pet Hospital for always saving my girls!

Carlos and staff always go above and beyond the “standard.” Recently one of my cats had been attacked by a dog. Though she wasn’t physically harmed, she was so terrified that she wasn’t able to move. In the chaos I thought she’d run off, hiding. 8 hours later I heard a plaintive meow. I ran to the spot where she’d been attacked. She was in a spot where water collects in the basement. It was 4:56pm. I called and Alicia said to bring her. Alicia met us and took Lola in. At 10:00pm that Friday night, Dr Yang phoned us. Her body temperature was 84°. Normal would be 101°. They were able

I used to work as a vet tech many years ago, and as I lived in various cities, have had many different veterinarians. Of the half-dozen over the past several decades, Dr. Yang is my favorite, both because he has deep knowledge and continuing interest in veterinary medicine, and genuine compassion for animals.

Cannot recommend Alicia and Dr. Carlos enough! They were recommended by our other family members and we've loved them since day 1! Can't thank them enough for their dedication to our fur babies and being so accommodating with scheduling or even picking up medications. Looking forward to many more years with Thornhill!

I had 2 Chihuahua mixes before and brought them to Dr. Yang for both their vet care. He and his staff are friendly, knowledgeable, and professional and I felt comfortable with Dr. Yang's level of care. I now have a 3rd Chihuahua mix and will bring her to Dr. Yang again. I would recommend this veterinary practice for anyone looking for an honest and reasonably priced vet. They also don't try to sell you unnecessary pet food, medication, etc. and leave it up to you to decide if you want to purchase it from them or another online source. I hope Dr. Yang and his staff remain in business for

We have 6 dogs, all rescues. Dr. Yang has been a rock in our lives for almost 10 years!! from puppy shots, surgeries to heart meds for our oldest guy and everything else in-between. I would not trust another vet but Dr. Yang. His team- Alicia, Kristina & Oscar always accommodates us (aka "the zoo") sometimes all 6 at a time!! They are like family to us!! Your pets could not be in better hands!!

I cannot recommend Dr. Yang and his office enough! Everyone in the office is incredibly kind (both to animals and humans!). Dr. Yang is also always upfront about prices which is very helpful especially as we only adopt senior dogs and both work for nonprofits. Recently, we had to say goodbye to our beloved Koukie and Dr. Yang was so caring to her in her final moments and also gave us space to grieve. The office has been absolutely excellent with COVID protocols as well. My first visit here I had a panic attack - something about seeing my dog so anxious triggered a panic attack for me - and the

Dr. Yang is the most reliable and compassionate vet I could have ever asked for! He has always been very clear when describing my 13 year old’s conditions. I feel like he prepares me, so that I can better understand what my dog is going through. Dr. Yang is such a great ally to have if you truly care about your pet!
Everyone at Thornhill Pet Hospital truly cares for every animal they see. Thank you so much for everything! I wish I could move you guys to Denver with me.

Dr. Yang is an excellent veterinarian with utmost skills and professionalism. Most preciously he truly loves and cares about his patients. Other than regular treatments he provides support and advice throughout the weekend on Friday, Saturday, Sunday, even Monday early morning hours before the hospital opens its door.

The staff Alicia is loving, caring and tremendously informative and helpful to every details. Thornhill Pet Hospital is the BEST VETERINARIAN HOSPITAL in San Francisco Bay Area offering ultimate love and care for the luckiest pets.

My previous vet retired. In looking for a new vet, Dr. Yang was highly recommended. Of concern to me was finding a doctor that was truly knowledgeable about epilepsy in dogs.

Dr. Yang in my experience knows about more treating this malady than the previous neurologists I took my dog to see with much better results.

The office staff is efficient, helpful, and very courteous. Another plus, the doctor and staff all are bilingual English/Spanish.

I have been living in Berkeley just 5 years, Thornhill Pet

Dr. Carlos Yang has been practicing for over 45 years.
He is very knowledgeable, amazing credentials, and successful practice. He had proven himself to be so personable the few times I've needed his services. First time we met was on Energency " cornea scratch " on my dog Misty, who at 14 recently passed away.

Dr Yang and his staff are the best- they pay attention to the important details- like explaining exactly what a procedure entails or how to administer medicine - how to make your pet better w/o trying to hook you into unnecessary expenses. They understood our worries about our pug having dental surgery and reported i. To us during the procedure to let us know all was going well... Dr Yang called us 2x to check in on Tiberius post surgery too- lots of in their vet care ....

Dr. Yang, Alicia and his team are absolutely kind, thoughtful, gentle, thorough but not invasive (they don't push unnecessary meds and procedures), attentive and just good hearted people all around.

I can't imagine what business owners are going through during COVID and such (and more this year..!!) I am so grateful he has kept the business open. He calls back after appointments (cases that may need follow up) and checks in personally. My girl is always taken care of and feel so safe to bring her here. Thank you all and stay safe and well!

I have been coming to Thornhill Pet Hospital for 2 years. Most recently, for my dog Shorty's Annual exam...

We were greeted warmly by the Staff and shown into an exam room. The Vet came in within a minute and treated Shorty with respect and compassion (she started by giving Shorty a treat!). She did a thorough exam and all the requisite tests. We were done in less than an hour and when I left the price was less than I'd expected --- it was very reasonable.

Convenient, nice staff, very welcoming, fair prices...what's not to like about that?

I give them the highest review possible

This is a terrific veterinary hospital! Dr. Yang is deeply knowledgeable and current in his practices and focus. He brings humanity and science together in a calm and professional environment. He took care of my 17-year-old dachshund and was there to put her down gently and lovingly when her end came. He is now the doctor for my 10 week old long-haired dachshund puppy who was happy to meet him...and we are all thrilled to be back in Dr. Yang's care!

Recently my cats have had upper respiratory infections and I have needed supportive care for them. My cat has not been eating and he is struggling with breathing as well. I was referred to Thornhill Pet Hospital from a close friend.

So I called this morning and spoke to Alicia about the situation and she put me on the phone with Dr Yang. He listened to the issue and arranged for a visit the same day which I appreciated very much. He helped give my poor little guy some fluids and recommended treatments for him. After the visit I told my wife that this is where I want to bring our fur-kids from

If you're looking for an honest, kind, and knowledgeable vet, look no further than Dr. Yang! He is a true professional who genuinely cares about the animals he treats. My two 100+ lb dogs are new to Thornhill after their 8-year vet in San Ramon relocated (yes, I would commute to San Ramon from Oakland as I refused to continue seeing Montclair Vet...read RIP off). I wish I would've known about Thornhill & Dr. Yang sooner as I've had the best vet experience with them in six months than I have in the last 8 years with other vets. Highly recommend!

Dr. Yang is an excellent veterinarian! When I call with a concern or question about my dog Picasso he is always there to help and solve my concerns. Alicia is awesome and she is very helpful. All the staff is wonderful and caring. They all provide great support.
They took excellent care of my British Bulldog puppy Picasso during his cherry eye surgery. The cherry eye surgery was a great success! Thank you Dr. Yang for an excellent job!
