Isabella MacArthur, Veterinary Assistant

Isabella has loved animals since birth. Originally from NJ, she grew up with 8 animals (3 dogs, 4 cats, and a bird). Isabella came to MD to go to college, only to realize her true passion was in animal care and decided to work at a local animal shelter here in MD instead! During her time there, she found she loved the veterinary side of animal care and is currently enrolled in Penn Foster to become a RVT. Although new to the veterinary field, Isabella joined Ruxton Animal Hospital with an eagerness to learn and serve her community’s fur-babies! Isabella currently resides in Towson with her 3 dogs and her cat. She enjoys spending time with her family, watching hockey (go Caps!), and playing piano.

Kimberly Wallander, Practice Manager

Kimberly is a seasoned Practice Manager and has a passion for building relationships, caring for others, and providing quality experiences to our clients and their furbabies. Entering the veterinary field in 2012, she quickly grew into a multifaceted leader, coaching a diverse number of teams in the DMV area. Dedicated to learning and development, she has acquired skills as a client advocate, veterinary assistant, operations specialist, trainer, and mentor. Kimberly proudly claims Charm City as her place of residence and is always looking for ways to serve the Baltimore community. Raised on Oahu, Kimberly loves taking in lots of sunshine. Outside of work, she enjoys exploring the outdoors and taking trips during the warmer months but prefers spending colder times of the year snuggled up on the couch at home with her cats, Monty and Lando.

Jessica Loudenclos, RVT

Jessica has been in the veterinary field for over 15 years. She is a graduate of Wilson College’s Veterinary Medical Technology program. Born and raised in Philadelphia, PA (Fly Eagles Fly!), she has lived in MD, TX, and AL. Jessica recently moved up from the deep south and is once again enjoying her snowy cold winters. Her furbabies (all rescues and some special needs) include 3 cats, 2 dogs, and 1 horse – and possibly chickens in the future. Her hobbies include horseback riding, reading, camping and a long term crochet project that never seems to end. Jessica is also a big supporter of her son’s Boy Scout troop. Adopt, don’t shop, and support your local animal shelter!

Sandy Wolbert, Veterinary Assistant

Sandy’s long love affair with vet med began in 2001! A Parkville native, she has spent most of those years at Ruxton Animal Hospital. Since a toddler she’s felt a special connection with the furry sort, and is happy to have ended up in her “dream job”! She enjoys all aspects of the veterinary field and her enthusiasm and energy brighten our exam rooms! Sandy’s own fur-kids include a Golden Retriever named Beaker, a pitbull named Beckett, and two cats (T.G. and Calista). Her personal hobbies include hiking, target shooting, riding horses (dressage specifically), and reading.
