When our 9yr old pit mix Stella needed a liver lobectomy we were concerned if she was even a candidate or if it would be successful. Our primary Vet and the Internist from AVSG both recommended VSS and Dr. Peter Sebestyen. His knowledge, expertise and compassion immediately put us at ease and the surgery was a success! The post-op care was amazing! The caring nurses and friendly support staff kept us informed of her recovery and even sent us a pic after she had eaten her first meal. That put our minds at ease. After discharge, Stella had issues with one of the meds but Dr. Sebestyen and the nurses assisted in finding a solution and kept checking in on Stella throughout the day. Dr. Sebestyen even called over the weekend to see how she was feeling, which we appreciated. Major surgery on a senior dog is a serious decision but we are glad that we listened to the skilled Vets who recommended VSS and Dr. Peter Sebestyen. A Solid Team of Professionals and Staff who we highly recommend!! read more

For the first visit they charged me over 1k for my cat only to say they can't figure out what's wrong with him. Even suggested that nothing was wrong with him. Another vet was able to help come up with a treatment plan and my cat got better. These people 'act' nice but not very good at what they do, I'm afraid. read more

Dr. Sebestyen performed BOAS surgery for my little guy BaBu. At first, I was skeptical because I didn't want him to go through the pain and discomfort. However I'm so glad my husband and I made the decision, knowing it would greatly improve his quality of life. BaBu is recovering well and doing amazing. I truly recommend De Sebestyen he did a remarkable job. Huge thank you to the entire team as well you guys are incredible read more

Responsive, ethical pricing, great doctors. Took great care of my dog when she had a biopsy.

If your pet ever needs surgical care, there is no better place than Veterinary Surgical Specialist. Our cat Oreo fractured two bones in his paw and required surgery, and from the moment we walked in, the entire team made us feel at ease. The staff was warm, patient, and thorough in explaining everything -- you could genuinely tell they cared about Oreo as much as we do. While the road to getting here had its bumps, the best thing our vet did was refer us to this team. I truly hope your fur babies never need surgery, but if they do, you will not be disappointed. Exceptional care, exceptional people. read more

The entire staff were very knowledgeable, confident, friendly, and calm which put me at ease immediately. I knew right away that I chose the right surgeon for my little Havanese, who had Pyometra prior to surgery. I was nervous of course due to the risks; but all of my questions were answered with patience and empathy. The facility was spotless. The team was responsive and so kind throughout the whole process. I am extremely grateful! read more

Best clinic. My dog had surgery done there. Recovery went very well!!! Quick and professional service

My hopes and prayers for a positive experience were met and exceeded by your entire team- from the front desk representatives answering the phones and helping me with questions or to check in, to the nurses caring for Benjamin in his post surgery stay (carrying him because he wanted to be held lol), to Dr Sebestyen who removed Benjamin's gallbladder mucocele flawlessly and called us on a Sunday to follow up on how he was doing post surgery during his recovery. We could not have asked for a better experience, treatment or care. Thank you, Dr Sebestyen for caring about our dog as you would hope someone would care for your own, and for treating us with respect and compassion. Thank you for coming into the room and looking us in the eyes, and shaking our hands. Thanks for your patience in answering our questions, hearing our concerns, and thank you most importantly for taking such good care of Benjamin and performing his surgery with no complications. He was off of all meds in 5 days and stitches out in 2 weeks. We are incredibly grateful to you all and everyone is doing an exceptional job. You are setting the bar high in your profession- thank you for renewing my faith in Veterinary facilities after some truly horrible prior experiences. VSS- OC, is being led by leaders who care about values, and lead with values and you can see that in how the staff carry themselves and the positivity that everyone exhibits. The entire feeling you get from the staff is that they are striving for the best possible care and experience and staff's morale is positive, and high. We can tell this entire team genuinely was providing the best care possible to Benjamin and it means the world to us. read more

Dr. Peter Sebastian was phenomenal with DUKE and the staff was amazing. We have a very vocal two-year-old GS. We were referred to Dr. Sebastian veterinary surgical specialist for Dukes Uninvited Anconeal Process. Medial Coronoid Disease. Surgical Procedure: Arthroscopy ( Unilateral Elbow. ) It was very easy to get an appointment for a consultation with Dr. Sebastian and appointment for Dukes surgery Was the following week. The building is very impressive and clean. Everybody was professional and kind and empathetic Dr. Sebastian is one of the best and understands and knows dogs, specially GS. The day of surgery drop off was 6 AM and the sweet gal greeted us and reassured us. He's in good hands and took DUKE back. We received text messages when DUKE was being prepped for surgery, going into surgery. Dr. Sebastian understands that German Shepherd's are accessible to Malignant Hyperthermia which means DUKE had a clean OR room, which I so appreciate! Because I do have Malignant hypothermia very rare one in 1 million for humans. Very common in German shepherds. We received updates and I could check in on DUKE at any time and I asked if I could see a picture of him and she says oh he just quieted down, but she said I'll try to see if I can sneak and get a picture, and she did and I cannot thank her enough. It warmed my heart and put me more at ease. DUKE came through surgery beautifully and the two pieces of loose bone were removed that never did grow correctly from developing in the womb. We went back today on June 14 for a suture removal and Dr. Sebastian remove the sutures no problem and he liked the bandage I purchased for DUKE on AMAZON. I asked Dr. Sebastian would you like me to send you the link to the bandage, and Dr. Sebastian said I'd like that very much, so I also sent Dr. Sebastian the link to the wrap I purchased for DUKE, which stops him from chewing or licking or scratching it. I especially appreciated the discharge papers online and in person. The DC Papers are amazing. I encourage everyone to read the discharge papers before picking up your pet they will answer every question you have so detailed. I truly appreciate the information so clear so helpful and we're still on the road to recovery which means DUKE is still quiet and down And he is the best patient. I truly believe DUKE read the discharge papers before I did.!! Thank you Dr. Sebastian and your team for taking excellent care of Duke.! You and your team are absolutely phenomenal and I highly recommend Dr. Sebastian and his team to anyone whose pet needs surgery.! if you ever have a question you may text or email them and send pictures by email only and they will respond quickly. Thank you for your empathy and the care that you gave DUKE during his surgery and hospital stay. We appreciate you and we thank you very much and Dr. Sebastian you are one in a million.! ! Payment was easy and medication instructions were clear and the medications were ready when we picked up Duke at noon the following day . On the day of DC Duke turned 3 years old March 31. What a birthday to be pain free and to come home. ‍ Thank you so very much! Wayne "Jeanette Scheiern." Duke Woof Duke said " Thank you for giving me my pumpkin bones my mom makes from scratch. Thank you Dr.Sebastian for taking me out of PN! Duke! Woof. read more

Our two year-old mini schnauzer was hit by a Amazon vehicle and his tarsal joint in his left rear leg was crushed. I took him to our regular vet and she did x-rays and said that that was beyond her training and she recommended that we take him to veterinary surgical specialist. The vet who worked on him is no longer there he retired however I have an idea that all the vets there are of superior quality, training, education and experience. The doctor saved our dogs leg! We drove to Tustin from corona because our vet recommended this facility. They really are surgical specialists!! read more

Very happy with the surgery performed by Thomas Keeshen, DVM, on our 13yr old dog Eddy. The delicate surgery to remove Eddy's perianal lumps was a complete success and luckily they turned out to be benign. Eddy's recovery was fast and he is doing great. Thank you Dr. Keeshen for your expertise and care and many thanks to the kind care team staff at the Veterinary Surgical Specialists in Tustin. We will see you again should the need arise.

Dr. Thomas Keeshen and the entire team at VSSOC gave my cat, Stormie, her life back. We traveled from Las Vegas, Nevada on July 25, 2025 for Stormie's TECA-LBO surgery consultation. From the moment we walked in the door, we knew we were in the right place. Stormie was diagnosed with a rare ear cancer called ceruminous gland carcinoma at just 3 years old. Dr. Keeshen took the time to explain everything clearly, compassionately, and honestly. He never rushed us, answered every question, and helped calm an incredibly stressful situation. Stormie underwent surgery the very next day, due to Dr. Keeshen accommodating us being from out of state, which I am immensely grateful for. She had a TECA-LBO (Total Ear Canal Ablation and Lateral Bulla Osteotomy) which is a major and delicate surgery to remove her entire left ear canal and Dr. Keeshen performed it with incredible skill. He called me to let me know as soon as she was out of surgery to let me know everything went well. Her margins came back clean, her lymph nodes were clear, and today she is officially cancer-free, living her best life. I truly believe that Dr. Keeshen's precision, experience, and thoroughness made all the difference. I also want to deeply thank the tech staff and the overnight nurses. They treated Stormie as if she were their own -- checking on her, keeping her comfortable, and making sure she was safe and cared for around the clock. Knowing she was in such loving, attentive hands meant everything to me, especially being so far from home. I texted the overnight nurses multiple times during her overnight stay being an anxious mama, and I received a response each time that put me at ease. Even after coming home, I was able to reach the nurses through the text number with any concerns I had during her recovery. They also were able to send her prescriptions seamlessly to her home vet here in Las Vegas. This experience could have been terrifying, but instead we felt supported every step of the way. If you are facing a serious diagnosis or a complicated surgical decision for your pet, I cannot recommend Dr. Thomas Keeshen and VSSOC highly enough. They gave me more time with my girl, and that is something I will be forever grateful for. Thank you again VSSOC and Dr. Keeshen for saving my Stormie! (This photo was sent to me by one of the amazing overnight nurses caring for Stormie during her stay at VSSOC) read more

My dog tore both CCLs and needed surgery right away. We were referred to this hospital by his regular vet and were able to secure an appointment the next day. After reviewing his X-rays, the team decided to perform surgery on both knees simultaneously, which is uncommon but necessary given the severity of the injury. Dr. Keeshan performed the surgery the very next day, and our experience exceeded all expectations. From the moment we interacted with the front desk to when we left, we felt our dog was in excellent hands, and they took great care of both him and us. The only downside is that although you have an appointment, you may experience significant wait times (sometimes up to an hour) but we understand they are busy, and the quality of care they provide makes the wait worthwhile. It's been over 8 months since surgery, and our dog has recovered beautifully! The incisions healed without infection, and the team provided us with comprehensive aftercare instructions and all necessary medications. We highly recommend Dr. Keeshan and Veterinary Surgical Specialists for their expertise and exceptional care. read more

Dr Walker is the best! My little dog was attacked by two huskies. After a failed surgery at a different vet i brought him here for a new surgery and he is healing perfectly now. It was a chronic case with a very hard to close infected wound. Thank you so much for saving my baby read more

My dog, Maggie (9yo GSD), has had chronic ear infections for 2 years, and we finally decided it was best for her to get a TECA. We were referred to VSS from her primary vet and dermatologist. The professionalism at VSS was first class from the first phone call, consultation, to vet techs, assistants, and Dr. Walker who performed the surgery. The TECA surgery seemed quite complex (in my eyes) for Maggie because the infection extended all the way into her cheek, confirmed by a CT scan that VSS performed. The surgery resulted in almost 7-8 inches of stitches from her ear to mid-cheek, when a typical TECABO surgery only has stitches around the ear opening. Maggie's recovery was not perfect, however the aftercare provided by Dr. Walker and team was top notch. They did not hesitate to schedule her in ASAP to recheck her sutures and how she was healing. We had several follow up appointments and she came back better and better each time. Before deciding to get a TECA, I researched day and night and was incredibly worried about how complex the surgery was, and how it isn't commonly done. But after the first consultation, I felt better because they mentioned they see it often and perform it quite often. All the doctors are Board Certified which also made me more confident in their profession. Maggie recently got her stitches removed after 3 weeks and she's doing amazing! From being in constant pain to no pain at all, she is noticeably so much more relaxed and happy now! VSS and team did an amazing job taking care of Maggie. I would recommend VSS without hesitation. read more

Omg I have to say What an incredible and wonderful experience that I had Veterinary Surgical Specialists in Tustin Irvine area close to the District shopping center. From the very kind and sweet receptionists, the caring and loving technicians and caretakers, super professional nurses and most importantly the incredible surgeon Dr Peter Sebestyen. The doctor was confident and very careful and did a beautiful job on my little buddys surgery. He explained all the risks and everything that was going to happen and spent a lot of time with me so that there was no surprises. He removed part of my dogs liver with a very large cancer/mass in it and less that 5 days later my dog is as good as new! Even the stitching is well done . Dr Peter Sebestyen is the best veterinary surgeon in California in my opinion . (He even has BEST in his last name)!! The follow up was great and quick responses from him and the team were really appreciated. They are very professional and you can feel good that they will do the best job they can do for your pet. Thank you Veternary Sugical Specialists in Tustin/ Irvine! read more

The place is very professional, clean and friendly. Dr. Sebestyen performed surgery on my french bulldog. He had a quarter sized mast cell tumor on his face. He removed in surgery and had clean margins. I couldn't believe how amazing of a hob he did. My boy came home the following day and I am so happy with the results. I was very hesitant to do the surgery since my dog is almost 11 yrs old. I am sooo happy I went through with the surgery and everything went so smoothly. I highly recommend this place! The staff are great too. read more

As a frenchie mom, surgery is scarier than ever. I went in for a consultation for BOAS & neuter for my boy, with Dr. Keeshen. The consultation was great, he was very thorough. He explained the risks, the recovery, what to expect. Fast forward two weeks, I dropped my boy off around 7am. I called a couple times to get updated before surgery. At 12 I got the text that he was going into surgery. At 1:18 Dr. Keeshen called me with the great news that my boy is awake and in recovery. He explained the next 12-24 hours are crucial due to post op complications. I called every hour up until 6pm, I was told I can text. So then I started to text every hour (may seem obsessive but I was worried) the nightstaff. They were all great, Julia, Kelly, etc. they answered every single text. Next morning at 9:30 I called and my boy was ready to go home. We are now home and in recovery! Thank you VSS for making this nerve wrecking experience a little easier on me. Communication was amazing and so was their staff. Cleanliness of the center shocked me! You couldn't tell it was for pets. I hope my boy never needs surgery again, but if he does-- I will make the drive here! read more

My rating reflects the exceptional level of care, professionalism, and communication throughout the entire experience. The surgeon demonstrated a very high level of skill and confidence, which gave me immediate trust that my dog was in the best possible hands. The procedure itself went smoothly, and it was clear that great attention to detail and expertise were applied. Equally important was the care provided by the staff before and after the surgery. The team was attentive, compassionate, and consistently kept me informed with timely updates on my dog's condition, recovery progress, and overall well-being. That level of communication made a significant difference and provided real peace of mind during what can otherwise be a stressful time. Overall, I felt fully supported from start to finish, and the combination of surgical expertise and outstanding post-operative care exceeded my expectations. What went well, and what you did best, was the combination of expert care and consistent, thoughtful communication throughout the entire process. From the moment we arrived, everything felt organized, professional, and focused on ensuring the best outcome for my dog. The surgeon's skill and confidence stood out immediately, and the procedure itself was handled with precision and care. What I appreciate most is how attentive and communicative the staff was before and especially after the surgery. I was kept informed with regular updates on my dog's well-being and recovery, which provided a great deal of reassurance. The team showed genuine compassion and took the time to answer questions, making sure I felt comfortable and informed every step of the way. That combination of surgical expertise and compassionate, proactive support is what truly set this experience apart. read more

Professional service, new modern clean facility and most importantly, excellent care. Everyone was caring and Dr Sebestyen was fantastic.

Top notch facility, board certified surgeons, excellent communication. Our dog had a splenectopy with Dr Craig. We received updates right before and after surgery and even during the overnight stay of our pup. Everybody was empathetic and professional and the outcome was perfect. The day after surgery our 14 year old pup seemed to be comfortable and painfree. The incision healed up well and doesn't seem to bother her at all, never even had to wear the collar of shame! Best surgery experience - only NO surgery would be better read more

This is an update from 2 weeks ago. I am very happy with how my dog, Emily's surgery went. I wasn't expecting the surgery to cost as much as it did. I was told that it would cost between 7,000-9,000 dollars. I ended up being charged 8,800.00 dollars. That is a lot of money for me and my husband. We don't have pet insurance and are both retired. I appreciate the staff and Dr. Harris. How well the surgery went. Dr. David Harris did an amazing job. read more

5 stars - Exceptional Surgical Care for Our Lab We can't say enough great things about Dr. Peter Sebestyen and the team at Veterinary Care Specialists of OC. Our Labrador retriever had been limping, and while we weren't sure of the extent of her injury, we were referred to this surgical office--and we're so glad we found them. From the very first appointment, Dr. Sebestyen was amazing. He used visuals to help educate us about what was going on, answered all of our questions patiently, and made sure we were fully informed and comfortable moving forward. When it came time for surgery, he personally called us before and after to walk us through everything. Once he got in, it turned out she had a full CCL tear and a mild meniscus tear--both of which he repaired. Our girl spent the night in their facility for monitoring and care, and we picked her up the next day. She was already up and walking, which amazed us. With a few modifications at home, recovery was very manageable. The office also made sure our pet insurance was submitted properly and helped streamline the claim process quickly and efficiently. Dr. Sebestyen's name regularly comes up on our Huntington Beach Nextdoor app--and now we know why. We recommend him without hesitation. From start to finish, this team took outstanding care of our fur child, and we are forever grateful. The only suggestion we can make is working on the wait time for clients, for a few follow up appointments it took longer than expected to get roomed. Again, would still recommend them to care for your pet! read more

I wanted to express my sincere gratitude and highly recommend your services! My husband and I were so worried when our 7-year-old pug, Crumples, was diagnosed with mast cell tumors on his front leg. We did extensive research to find the best treatment and specialists, and we are incredibly grateful to have found VSSOC. Thank you, Dr. Sebestyen, for the successful surgery on Crumples and for the exceptional care and treatment he received throughout his recovery. Crumples has always been anxious about vet (and grooming!) visits, so we were pleasantly surprised that he was always very eager to go to VSSOC. This speaks volumes about the wonderful experience he had with the nurses who attended to him during each visit. Thank you so much! We also want to thank all the front desk staff who are consistently attentive and accommodating. You are all the best. We are so relieved that Crumples' cancer scare is now (hopefully) behind us, and we are very happy that we chose VSSOC to help us through it. read more

We are immensely grateful to have found Dr. Sebestyen for the lifesaving leg amputation on our precious boy. Diagnosed with osteosarcoma, we were left no choice but to amputate his arm. Like any loving pet owner, worry pervaded our days leading up to the operation-- who in their right mind wants their baby to lose their arm? Such a serious and life altering circumstance to face. Dr. Sebestyen proved knowledgeable, experienced and honest: a personality that is vital during such circumstances. After the operation, our boy left the hospital seamlessly, no pain, no suffering, just seeking his new sense of balance. It is barely 48 hrs later and he is feeling wonderful. Feeling deep appreciation for the team at VSS - including Marsha, the most welcoming receptionist - for all the ways we feel our baby was well taken care of. Natural to endlessly research and contemplate doctors like we did but put your faith in the doctors here and trust that all will be handled with ease. Much love read more

They did an amazing job caring for Pokey and removing the mass in her shoulder! Dr. Keeshen was so professional and caring.

Dr Sebestyen is an outstanding surgeon. He surgically repaired our springer spaniel's rt anterior cruciate ligament two weeks ago. Her post op course has been great. She does need to be watched closely so that she doesn't exert herself but she has not been limping or showing any sign of pain. Eight years ago when she was only one year old he operated on both front shoulders with an excellent result. We have had two other dogs over the past fifteen years that Dr S. has operated on with similar excellent results. I highly recommend him. read more

Words cannot describe this place!! It's beautiful, clean, and filled to the brim with a bunch of wonderful and caring staff. My frenchie needed BAS surgery (widening of her nostrils and shortening her palate) to help her breathe and her regular vet recommended VSSOC in Tustin. From the moment of her consultation, to the day we picked her up after surgery, was top-notch. No complaints. It was real hard leaving her overnight with a bunch of people she didn't know and it being such a scary experience. Thank you to her nurses, Chelsea and Gabby. You loved her like she was your own. Thank you to the receptionists who put up with me while I was being impatient when picking her up. And THANK YOU Dr. Keeshen for taking exceptional care of my baby girl - she looks beautiful! read more
