Sarah Romano

Sarah Romano

Head Veterinary Technician

Sarah began at Danbury Animal Hospital and Versatile Vets in 2019. She’s our talented and enthusiastic head veterinary technician, as well as a Certified Phlebotomist. She finds joy in helping pets, knowing that they have a special bond with their humans, and relishes being surrounded by supportive teammates.

The way she sees it, she never had a choice to pursue another field. Her first childhood memories include sneaking baby birds into her room to heal them after falling from their nests. She would also feed stray cats and watched in fascination as they gave birth. Her drive to help animals in need led her to work in the veterinary field for over a decade.

Sarah graduated from Danbury High School, class of 2008. She enjoys traveling, going out to dinner, and hanging with her family and fur kids. She’s always appreciated her family’s traditions and quality time. Her pet family includes two French Bulldogs, Henri and Hailey, both of whom come with a handful of adorable and funny nicknames.

Desiree Filipek

Desiree Filipek

Veterinary Technician

Desiree joined our staff in 2020 and adores being part of a “fantastic” team that helps families and their pets. She enjoys not knowing quite what to expect each day and loves making a difference for each pet she helps.

She attended Middlesex Community College and graduated in 2015. In her spare time, Desiree likes to work out, explore mother nature, and with her husband chase after their three “wild” sons: Dominic, Roman, and Kylo. Her feline family includes Dallas, Martini, Smudge, and Kiwi. 

My cats always loved Dr. Quaintance and Dr. Kaeser so when they started this endeavor, booking a kitty checkup was a no brainer. We had an excellent visit, much less stressful than riding to an office, and now my skittish boy, Tiki is curled up on my lap, happy as a clam. Even got a little mani-pedi trim for the infamous Spitfire as a bonus. Just a really fantastic option to have with truly exceptional vets. Can’t recommend enough!
