Clayton W Simon, DVM Laguna Niguel, California

We just moved to California and was referred to Dr. Simon by a neighbor. Our dog had a growth in her nostril that was growing and becoming ulcerated after we tried many courses of treatment. Before Dr. Simon did a biopsy he wanted to send us to an oncologist. Of course no specialist will see the dog without a biopsy confirming a cancer diagnosis. We went back to get a biopsy and he once again told us the 2 scenarios of our dogs prognosis without any information. Whether malignant or benign a portion of her nose would need to be REMOVED! At that point we went to a different Vet to get a second opinion and a biopsy. Thankfully our dog will NOT need to have her nose removed and it is not cancer or anything life threatening. He upset us terribly with no information to substantiate his ridiculous course of action he thought necessary for our dogs treatment. Do yourself a favor and DO NOT GO TO DR. SIMON!!

Dr. Simon was fairly priced and treated my Golden with care.

Great doctors and extremely friendly and helpful staff.

Very nice people here. Thank you.

Staff was very polite and courteous. The doctor was passionate and professional.

Such nice people. Dr was fantastic

Great 1st time visit! Highly recommend -Dr. Simon & Staff were efficient, professional & friendly. Dr. Simon was able to calm my elderly fearful dog & gave her a thorough exam. I loved that he discussed different options for treatment & together we developed a plan of care to address her pain & mobility issues. Dr. Simon is very knowledgeable & I appreciated his honesty - he did not try to make me change the medicines/supplements/food that have been working for us but explained several improvements for my dog's care that should help her. I look forward to working with Dr. Simon & his Team in the future.

Dr. Simon and Stevens, and their crew are great! I highly recommend the practice! Winston gives them a paws up.

This is my favorite vet clinic!

Ana and Nic, my cats, got their annual checkup and rabies. Everyone is so sweet and things progressed as expected.

Love it here brought my dogs here for many years the staff are amazing and they always are smiling and joyful

We were so fortunate to have these vets down the road from us. We had moved into the neighborhood a few days earlier and weren't expecting to need a vet so quickly as our dogs were up to date with vaccines, etc. However, our two dogs were rough playing in our backyard and one of them suddenly yelped and went down to the ground in pain. We were able to drop him off so that Dr. Desowitz saw him that day and called to let us know what her thoughts were before moving forward with additional tests and x-rays. Our dog is now scheduled with Drs Simon and Desowitz for surgery as he tore his cruciate ligament in his back left leg. We are extremely pleased with the treatment both we and our dog received and feel lucky to have found Marina Hills Animal Hospital.

The techs we're kind but the doctor was judgemental and pushy. Guilted me about my cat getting fleas because we missed a medication dose while we were moving to a new home. Tried to upsell me on the flea meds that they use. Tried to upsell me on a "vip" program where I would pay them in advance for future visits . . .

My mini dachshunds back went out. They were amazing took such good care of him and his extremely painful back.

Trust Dr Simon and staff,wouldn't go anywhere else,they really take wonderful care of your pets ..

High price but they do know what they are doing. Dr. Simon is very good.

Super professional, detailed and friendly. Your pet will thank you!

Absolutely the Best Veterinarian Animal Hospital! Excellent customer service. Good and fair pricing. Definitely recommend taking advantage of their Pet Care Rewards membership program. Staff Excel in compassion, knowledge, experience and humor. My family adores Dr. Stevens. She's amazing.We are grateful for her consultations, attention to detail and clear concise diagnosis with explanations. Dr. Stevens recently diagnosed Dental issues for our 8 yr old baby when we could not figure out why she was so "low energy" we thought it was age related. Dr. S. recommended and performed dental surgery. Post surgery she has become a mischievous kitten again! The change of her is remarkable! Yaga's succinct caring nursing/ Tech skills are unmeasurable. Sue's invaluable assistance, positive energy and thoughtfulness along with Sarah Jessica make us feel like they're part of our family. Collectively above are the very reasons why my husband and I drive from Pasadena. Thank you Dr Simon for creating and providing this unique exceptional Hospital.

We wouldn't take our fur babies anywhere else. Truly caring staff and they provide an awards program which really helps. Love these people and they love their work.

Caring and compassionate. Love this vet.

Friendly, warm, efficient. My dog Jake is feeling much better. Tku

The people at Marina Hills Animal Hospital were so great with my dog. We are new to CA and we were treated like old friends.

Wonderful staff and always caring for our pets, since I'm local, I always see them walking the dogs and taking them out MULTIPLE times throughout the day!

My dog had stones that was obstructing him pretty severely. They were very helpful and knowledgeable. The doctor took the time to explain everything to me so I could understand. The staff was very friendly and incredibly nice in very stressful time for me. I would recommend this place any day of the week.

Cannot Recommend –this incident happened a few years back but it's a situation that should never occur at any veterinary practice ever! What made this experience so awful was Dr. Tina Stephens trying to run up hundreds of dollars of tests on a puppy that she was told had Intra-Trac 3 vaccine 8 days earlier (this vaccine is for Adenovirous 2, Parainfluenza & Bordatella). The puppy was eating normally, and in fact, had a voracious appetite. Yet this vet wanted to do a$ 178.00 blood panel and $180.00 worth of x-rays and various and sundry other things adding up to $600!!! IMO, a good vet LISTENS to the information a client conveys in terms of symptoms, events and circumstances and proceeds to rule out things in order of probability. Treatment was declined because it seemed as inappropriate as Dr. Stephen's theatrics seemingly intended to frighten. The puppy in question was later taken to a veterinary practice on Laguna Canyon Rd, where the veterinarian determined she had "Kennel Cough" (Bordatella) from her recent intranasal vaccine. No hysterics, no fear tactics, just plain old excellent diagnostic skills ...

Dr Clayton Simon was great very informative and friendly. The whole staff was very inviting and Sue at the front desk is very sweet and organized.

I have been using Marina Hills Animal Hospital for over 4 years and although I recently lost my dog, I will continue to recommend them and, someday in the future when I adopt a new friend, use them again. Dr. Simon, Dr. Stephens and their staff are extremely knowledgeable, caring and compassionate. They always discussed all options available along with costs and potential outcomes so I could make the best decision for my dog. Taking your furry friend to the vet is nearly always stressful...this team makes it much easier with their friendly, calm and caring attitude...I cannot recommend they highly enough!

This hospital is fantastic! We moved to CA recently and had to find a new vet for our dog and 3 cats. I have been there twice, once for my dog's injured leg and once for a well visit for one of my cats, and I couldn't be happier. Super friendly staff, clean and welcoming atmosphere, and great service. At both visits, after consulting with the doctors, I received a breakdown of the recommended treatment and associated fees. Nothing was done until I gave consent to all treatment and charges, which makes for a pleasant check-out - no surprises when you get the bill! I highly recommend Marina Hills Hospital to anyone looking for a caring veterinarian's office.
