Dr. Hayek and Dr. Negvesky’s passion is education and helping pet owners understand how to best care for their furry family members. Not only are the doctors passionate about practicing high-quality, modern veterinary medicine, but they are also involved in the community. They eagerly participate in local events where they can share their knowledge and serve as a trusted source of information about pets.

Drs. Hayek and Negvesky met in 2015 while working at another hospital together, and they were instantly great friends. In 2017 they decided to get together to create their own hospital, a place where they can practice progressive medicine in a friendly fun environment. They’re very supportive of each other and work together to ensure they have plenty of work-life balance and time to enjoy their personal lives and families. They also spend a lot of time together outside of work and like to try new foodie restaurants and go shopping, as well as double dates with their husbands.

Anything to do with the beach and ocean; traveling with Alex, her amazing supportive husband of 11 years; riding her beach cruiser anywhere and everywhere; baking and eating pastries; watching movies & TV with aforementioned amazing husband; learning new things; and doing Pilates and yoga to help feel strong and balanced.

You may find her...

Esoterically quoting her favorite movies; entranced by petting kitties; staying up late for no good reason; and enjoying long conversations with friends and clients about anything and everything.

An Air Force brat, has lived all over the country but always came home in the summers to visit family in SoCal; mom Sherry is a dental hygienist and dad James is a hospital administrator; husband Alex (did she mention how amazing he is?) is a computer systems engineer who manages a technology team for a financial firm; cats Fiona (rescued at 8 weeks old & is now 15 years old) is a super sweet gray domestic shorthair who’s always by her side, and Morgan (rescued at 1 year old after spaying her in veterinary school for the local humane society & is now 7 years old) is a crazy loving ball of fur tortie/calico mix.

Favorite Parts of Her Job

Building relationships with pets and their people; the fact that medicine is like putting together puzzle pieces to devise a specific treatment plan for each patient; the satisfaction that comes from fixing things; and the satisfaction that comes from fixing things (castrations are her favorite!).

Dislikes

Mayonnaise (with the fiery passion of a thousand suns!); rude people; and waking up early.

Superpowers

Detecting heart murmurs in pets that others can’t hear; making friends easily; and a wickedly sarcastic sense of humor.

You may find her...

Relaxing in her backyard with her dogs, drinking tea, and soaking up the sun.

Personal Stats

Got married in 2017 to the love of her life, Jeff. He immediately got along with her dogs (made her love him even more), a Chihuahua named, Dulce (De Leche) and a Jack Russell terrier mix, Pace.

Jeff and she are currently pregnant and impatiently waiting to meet him!

Favorite Parts of Her Job

Meeting people with their own pets and learning about them. Making sure that the people around her are happy and go home happy. Finishing up with a day that is filled with helping animals and their human friends.

Dislikes

Marzipan, coconut flakes (except for the real fruit), driving slow, people who dislike dogs and cats.

Superpowers

Taking photos of things in a different perspective and having them turn out awesome! Also great at working the microscope!

Sarah Deming, RVT

Sarah has been in the veterinary field since 2013. She grew up in Orange County and her love of animals began with her very first steps! Sarah and her husband David had their hearts stolen by their ever growing family: Goblin a tuxedo kitty, Clover a cute little black cat, a rottweiler-mix named Coo-Coo Ze Pants (the name is utterly befitting), and two courageous chihuahuas: Grr and Pixel. Sarah not only works at TLAH, but in her free time she fosters bottle-baby critters for the nearby rescue organizations. When she finds a second to spare, you’ll see her perfecting monster-movie make-up looks, and cracking up at the most terrible pun jokes.

What the doctors love about her:
Sarah is very outgoing and friendly, and adds a lot of fun to the hospital’s atmosphere. She’s very passionate about her job and is always learning new ways to improve her knowledge and skills, so that she can take the very best care of your pets!

Katie Whittemore, Veterinary Technician

My name is Katie and I’m so excited to be working at TLAH! I graduated with my AA in Environmental Science in 2011 and worked with a couple local nonprofit environmental groups before deciding that veterinary nursing was my true calling. I have loved and wanted to work with animals since I was very young so becoming a veterinary technician was the right choice for me! I went to Heritage College and OCVAS to get my vet tech certifications, and I am hoping to have my RVT license by the end of the year! I have worked as a veterinary assistant since 2015 and have loved every minute! When I’m not at work, my favorite activities are: spending time with my boyfriend Dylan and our pets Annie and Perla, hiking/camping/enjoying nature, watching new shows and movies on Netflix, or reading.

What the doctors love about her:
Katie’s genuine love of animals truly shines through. Not only does she love helping animals in need, but she is a very understanding and patient person to work with. She continues to grow in her technical skills. Our clients love her and ask for her when they need questions answered.  We could not have asked for a better person to work here and we love her!
