Groomer

Victoria
Groomer

Victoria

Victoria (Vicky) is joining the OSSVH team in May 2023. She grew up in New Jersey and started grooming there 12 years ago. Before that, she worked with pets her whole life, caring for them and working in retail. Victoria spent the last 6 years in Orange County, California as the Head Groomer at the #1 grooming salon in the Laguna beach area where she really honed her craft. She took specialized courses and went to pet expos to keep up with the latest trends and tricks of the trade. Victoria continues her education and perfecting her skills to make sure she can give her clients and their pets the best care and products possible.

Being a professional pet stylist and canine esthetician, she’s taken different courses on skin conditions, allergies, and practices fear free grooming techniques. Victoria has always been super patient with difficult dogs knowing that some dogs just don’t like certain things and she’s always up for a challenge, She’s had clients call her the “Nail Ninja” for some of the more difficult dogs. Safety always comes first with Victoria. Most importantly, she prides herself on the bonds she gets to share with not only her people clients but their pets who make her job a passion. Gaining all dogs’, especially a difficult dog’s trust is ultimately her goal in the grooming process.

Victoria enjoys doing breed standard cuts, but my absolute most favorite part of the grooming process is doing a good de-shed on a double coated breed. She loves creative grooming -if you bring a picture of what you want your dog to look like, she will do her best to make your wishes come true, like a grooming fairy godmother.

Victoria has two dogs; Morty, a hound mix who was a foster failure, Luna, a Peek-a-poo, and a cat, Poop, an extremely vocal tabby. She recently moved to the DMV area to be closer to family. When she’s not grooming, she enjoys cooking recipes she finds online, painting and creating art, as well as binge watching the Office and Bob’s Burgers.
