Dr. Erica Merrill

Dr. Erica Merrill

Principal Veterinarian

Dr. Erica grew up in Colorado and completed her undergraduate degree at the University of Colorado at Boulder in 2006. She took a four-year break to spend time in the workforce and did a six-week trip to Arusha, Tanzania. There, she volunteered at a nursery school, as well as a hospice and orphanage for those affected by HIV and AIDS. She graduated from the University of Minnesota College of Veterinary Medicine in 2014 and completed a year-long internship at VCA Mission Animal Referral and Emergency Center in Mission, Kansas.

She always had a soft spot for the PNW, having spent summers at her grandmother’s house in Indianola, Washington. She accepted a position in Washington and has worked in the emergency field for the past 3 years. While emergency was exciting, she missed the continued client and patient interactions and moved to general practice. She has a Whippet mix named Buster, a Chihuahua mix named Ollie, and a fat Siamese mix named Monty. In her free time, she enjoys walking and spending time with her furbabies, playing the piano, hanging out and going to late-night diners with friends, and watching movies of all genres. She has a special place in her heart for angry Chihuahuas and nervous Greyhound breeds and loves all of the dogs and cats that walk through our doors.

Dr. Carol Jeanne Kraneburg

Dr. Carol Jeanne Kraneburg

Associate Veterinarian

Dr. Carol Jeanne Kraneburg grew up in Long Island New York and started her career in 2010 doing animal rescue at the world’s largest no-kill rescue, NSAL. She graduated with a degree in Developmental Genetics from Stony Brook University in New York, where she taught the same subject. Dr. Kraneburg attended veterinary school at Auburn University in Alabama (so please don’t mind if she says y’all) and graduated cum laude with honors. While there, she was a Merial scholar and is now published internationally in the Journal of Feline Medicine and Surgery for her work with vaccine creation. She has traveled nationally to present her research. Dr. Kraneburg especially enjoys dermatology, cardiology, and hospice care. Dr. Kraneburg has extensive experience with heartworm treatment and enjoys the “odd cases” she somehow seems to attract. She lives in Kent with her husband, Wayne, who is an engineer and soldier in the National Guard. They have two fur children – Molly, a 9-year-old Cairn mix, and Charlie, a 12-year-old special needs Yorkie-Poo. Her hobbies include classical painting, Irish music, gardening and she is always doing a project around the house.

Mary Crouch

Mary Crouch

Practice Manager

Mary Tremblay-Crouch was born in Washington, D.C., and has lived all over the United States. She went to high school in Bloomington, Minnesota, and attended college at Marquette University in Milwaukee, WI where she ran track on a partial scholarship. She graduated with a BA in Psychology and Communications. Immediately after graduation, Mary joined the Peace Corps as an English teacher in the French-speaking country of what was then Upper Volta (now Burkina Fosse) in Africa. Mary eventually found her way to the Pacific Northwest where she now resides. She remains passionate about horses and animals of all kinds.

Mary came late to the veterinary field having worked in various occupations – one of which was owning her own business working with physicians of all specialties for ten years. When she sold her company, Mary was fortunate enough financially to be able to take a “temporary” job as a kennel assistant. It’s funny how life does not always work out the way one envisions. In Mary’s case, it turned out so much better. She began a long-standing love affair working in a field with both animals and people. Mary says it “feeds her soul” and she means it!

Mary has been in the veterinary field for over twenty years. She started working at Renton West at the end of November 2019. Working alongside Dr. Merrill and Dr. Kraneburg is exciting and she feels blessed to be a part of this dynamic and growing practice. Mary looks forward to many more years of service to the community.

Veterinary Assistant

Cydney was born and raised in Kenmore, WA. Cydney started working with animals in 2005 – volunteering at MEOW cat rescue in Kirkland. From there, she worked her way up in the veterinary field in various positions such as kennel attendant, receptionist, veterinary assistant, ER/ICU, and triage nurse, hospital and practice manager, and unlicensed veterinary technician. She has grown up with and cared for various exotic animals such as rodents, fish and aquatic animals, and small reptiles. She is currently enrolled in Pennfoster to get her veterinary technician license. Cydney moved to Renton two years ago with her boyfriend Geoffrey, their 12-year-old beagle Brady and 11-year-old domestic short-haired gray and white cat Charlie. She started working with the amazing team at Renton West Veterinary Hospital in March 2020 after searching for the right hospital to call home. In her free time, Cydney enjoys playing video games, listening to music, watching e-sports, and exotic animal medicine shows; she also helps out with her boyfriend’s audio and karaoke business. Cydney is the cat whisperer on our team!



Jennie grew up on a non-working farm in the mountains of Colorado. Her love of animals started when she was young. She spent most of her time riding horses and training dogs, chickens and many other animals. She spent the last 15 years as a preschool teacher, as well as continuing her passion of working with animals. Jennie is a dedicated volunteer with Regional Animal Services, where she has put in over 7,000 hours. She specializes in cat behavior and dog training. She also fosters kittens and small animals as well. She recently fell into this role after “retiring” from teaching to pursue working in a field where animals are the focus. Jennie has been married 21 years and has 3 grown children (Tim, Kirsten, Tanner), 6 tarantulas, a scorpion, a Bearded Dragon (Phoenix), 3 cats (Ben, Anakin and Ember), a Labrador (Ronah) and currently a foster bunny (Olive).


Jensen was raised in the Greater Seattle area and graduated from Kentlake Highschool. She is currently enrolled in Penn Foster Veterinary college, where she is pursuing her Veterinary technician’s license specializing in feline and canine care. She joined our dynamic team in August of 2020 and she brings so much to the table! Jensen is exceptional at handling frisky kitties. She loves working and learning alongside our amazing team! In her free time, you can find Jensen hiking and exploring our great Pacific Northwest. If she’s not out and about, you can find her lounging with her favorite feline, Izzy. Jensen is an awesome addition to our team and we are so grateful to have her on board.



Kayln grew up in Southern California and moved to the Pacific Northwest 6 years ago. She has been in the Veterinary field as an assistant for almost 4 years and joined the Renton West team in May 2021. She has grown up with animals her whole life. She currently has a 3-year-old cocker spaniel mix that goes everywhere with her. During her free time she likes to explore the Pacific Northwest and travel, when she isn’t doing that you can find her at home studying to become an LVT as she is currently enrolled in Penn Foster.



Raised on her grandpa’s farm in Springdale, WA, McKenna was surrounded by animals before moving to West Seattle as a young girl.  During her summers at Vashon High School she volunteered in Tanzania, Africa at a primary school teaching the children English.  She helped build desks, garden and paint the school.  McKenna also traveled to Chiang Mai, Thailand to teach English and build bathrooms at an orphanage.  During these two humanitarian trips McKenna’s love for animals grew as she spent time bathing elephants and making natural medicines for them, explored animals in their natural habitats, and sadly saw many dogs and animals in need.  She hopes to return to do humanitarian vet work internationally.  McKenna attended PIMA Medical Institute where she received her Veterinary Assistant Certification in 2021, with plans to become a Veterinary Technician.

McKenna has a black lab whippet named Stoney and loves looking after her roommate’s dogs.
