Sarah Flahaven

Office Manager

Sarah Flahaven grew up in and around Cincinnati, Ohio.  She grew up around with all kinds of animals: cats, dogs, chickens, goats and rabbits.  Living in a rural area, she showed goats at the 4-H fair and loved raising different kinds of animals.  She has a special place in her heart for beagles, as she had four pet beagles as a child.  After moving to Chicago, she graduated from Loyola University Chicago with a bachelor’s degree majoring in criminal justice.  She also obtained her paralegal certification and worked for a while as an investigator.  After meeting and marrying Dr. Flahaven, she decided to change her career path and dedicate her life to helping him and the pets at Deer Grove Animal Hospital.  It has been the most fulfilling career path thus far and spending time with the animals is the best reward.  She spends most of her free time with her children Charlotte, Margaret, Violette and William and her fur babies: Lumpy, Kiki, Stinks, Dweebs, Callie, Lil Cat and Moonie.  She is a Fear Free certified veterinary professional.

Perla Garcia

Vet Tech Assistant

Perla Garcia became part of the team in August of 2021.  She has two crazy dogs, Camila, a Jack Russell terrier, and Rocky, a Shih Tzu.  Both came from homes that couldn't take care of them anymore.  They landed a spot in her house and are probably the happiest dogs alive!  Perla never knew how much she loved animals until she found them, which led to her working here as a vet tech assistant.  She has so much fun meeting all different cats and dogs and getting to know their personalities.  It truly is so rewarding for her to be part of the team helping our patients live happy and healthy lives!  She is currently working and studying to become a certified veterinary technician.
