Registered Veterinary Technicians

Training Coordinator

Gretchen Gaston, BS, RVT

Gretchen joined us in October 2014 as a Registered Veterinary Technician with a wealth of knowledge being in the veterinary industry for 19 years!  In 1994, she obtained a BS in Animal Science from UC Davis. She worked on a Thoroughbred Horse Ranch for 3 years, Emergency and Critical Care for 17 years and has taught classes at the Santa Rosa Junior College for the RVT program, as an Adjunct Faculty Member for 4 years. She has been an RVT since 2000, and tutors those that are going to take their exams for the past 11 years with a 98% pass rate! Gretchen joined our team as a Training Coordinator to share all of her knowledge and train our technical staff to be able to provide the best patient care! You may even catch her doing some overnight shifts, because her heart is still in providing exemplary patient care to our critical patients!

Gretchen loves to spend her free time gardening, cooking, reading and challenging her brain at word games! She shares her home with her boyfriend, Dan and his three children, Grace (9 years old), Austin (15 years old), and Brandon (18 years old). The life in their loving home is provided by "Bonnie Boo", their 1 ½ year old Dingo mix doggie!

Gretchen’s favorite part of veterinary medicine is in two parts! She loves to teach, coach and mentor/ train veterinary medicine to eager young minds (and not so young minds!). Her other favorite part is Emergency and Critical Care, because there is no better feeling to her than to save an animal’s life!

Leah’s favorite aspect of veterinary medicine is having the capacity to understand the science behind medicine, coupled with the physiology of animals to be able to succeed at pets well again!

Wanda McCalmon, RVT

Wanda is one of our newest team members! She started working in November 2014, as a Registered Veterinary Technician. She has been in the industry for 12 years and has been licensed since 2010! She graduated from the Veterinary Technology Program at Carrington College (when it was Western Career College) with an Associates Degree in Veterinary Technology!

Wanda loves spending her time outdoors fishing and hiking with her family. She uses drawing as her creative outlet. She comes from a very large family and has made quite a large family of her own! The non-human members of her family are 2 bearded dragons, "Thorn" and "Spike"!

Wanda’s favorite aspect of veterinary medicine is seeing the smile on the owner’s face when they are able to take their pet home from the hospital! In addition, just knowing the difference that she made in that pet’s and their family’s life to have brought in a sick pet and walk out with a happy and healthy member of the family!

Courtney Gutierrez, RVT

Courtney joined team Sunset July 2014, as a Registered Veterinary Technician. She worked in the retail and food industry from high school and up through college.

Once she finished college, she started working in Vacaville in a small animal practice for 1 ½ years, then came to Sunset. She passed her state boards and officially became a RVT in January 2014!  Courtney has been able to integrate her skills into several areas of the hospital; surgery, emergency, patient care, client education and she has been known to do a few dentals!

She loves to go hiking with her German Shorthair Pointer, "Tilly" wherever their adventures take them! She also likes to read, “The Walking Dead” and “True Blood”. She shares her free time with her younger brother.

Courtney says her favorite part of veterinary medicine is that she is able to make a difference in the quality of life for her patients! In order to accomplish this, she educates clients about their pets and ways they are able to prolong their lives through current medical treatments and preventing future health issues. She loves to learn new things everyday and shares her knowledge with others enthusiastically!
