Meet Our Team

Tim Walters grew up in the San Fernando Valley in Southern California. Having always had pets, Tim’s desire to be a veterinarian goes back as far as he can remember. His first real job was working at a boarding facility attached to the local veterinary clinic. When he was old enough, he transferred to the main hospital where working as an animal assistant cemented his desire to become a veterinarian. After graduating from Pierce College, Tim attended veterinary school at UC Davis and completed his degree in 2007. 

After vet school, Dr. Tim returned to his original hospital to work as a veterinarian, and did so for over 3 years. Tim then moved to Columbus, Ohio to be with his then friend and now wife, Emily while she completed her residency in veterinary clinical pathology. They moved back to California in 2013 and have now settled in Southern California with their golden retriever named Kirby, rescued poodle terrier mix named Lola, grey tabby cat named Phoebe and their box turtle named Tina, who Tim rescued as a teenager. Tim enjoys spending his free time outdoors, hiking, biking, and camping. When not outdoors, he is usually watching sports with friends or listening to music.

Jenny grew up in Laguna Niguel CA and went to Dana Hills High School. She graduated in 2015 as a student-athlete in softball from Seattle University with a BA in Liberal Studies. Jenny has always had a passion for animals and felt a calling to work in the animal field. Jenny started working at Rancho Niguel Animal Hospital in July 2015. She decided to continue her education in veterinary medicine and received her Veterinary Technician certification from Platt College in 2017.

Rachel is a Southern California native. She graduated from Trabuco Hills high school and attends the local college. She grew up with cats since her mother was not too fond of having dogs in the home. Since Rachel felt void of having her own dog she gave lots of love and care to all of her friends’ dogs. She is new to the veterinary field and is greatly enjoying the work. You can find Rachel in her spare time picking and smelling flowers, going on adventures, or drinking coffee. Look close and you might see evidence that Rachel had a makeup spill in her car prior to her bio photo shoot. Rachel’s calm demeanor helps us to keep a chill vibe at the practice for our patients and they love it!

Jenna is originally from New Jersey and moved to California in January 2018 with her boyfriend and her German Shepherd, Zoey. She has always had a passion for animals and began working with animals while studying animal science at the University of Rhode Island. This education gave her a solid background in veterinary care. Jenna is the gentle soul who is at your pet’s side when receiving medical or surgical treatment at our practice. In her free time she loves practicing yoga, making jewelry, and being a professional beach bum.

Sarah was born and raised in SoCal and is currently going to school for her nursing degree. She started here at RNAH in May of 2018 but has many years of experience working in the veterinary field and loves working with animals. Outside of the office, you will find Sarah spending time with her husband and family, going to the movies, the pool or just reading a good book. Sarah and her husband are avid travelers and love getting away when they have time. Her family pets include: Duke, a tank of a yellow Lab and Cooper, a Dachshund that loves snuggling.

Growing up on a farm in Indiana, Cadie’s compassion for animals started fresh out of her mother’s womb. She spent her childhood helping her father out on the family farm while completing her ten year 4-H Membership at the Tippecanoe County Fair. After receiving her Bachelor of Science Degree from Purdue University in 2010, she moved to Orange County, CA to pursue her career. After years of professional pet sitting in her free time, she officially became a Crazy Dog Mom of her own fur child in 2016- a boxer mix rescue pup named Mellie. We always know where to find her when she’s not at work- it’s either the dog beach or dog park as Fur Mom Life is the best life for Cadie! Your fur babies can call her “Auntie Cadie” as you will most likely find her consoling them like one of her own.
