About Dr. Kassell

Dr. Natasha Kassell

Dr. Kassell received her veterinary degree from the University of Pennsylvania in 1994. She then practiced conventional small animal medicine in Gig Harbor, Washington. Although she loved being a vet, she found herself frustrated by what she could offer her patients with conventional medicine alone. When she learned of a year-long course specifically for veterinarians in nutrition and homeopathy, she jumped at the opportunity to take it.

The experience transformed her veterinary practice and her life.  After completing the course, Dr. Kassell opened a small animal holistic house-call practice in Gig Harbor, specializing in preventive health care and homeopathy for dogs and cats.

In 2002, Dr. Kassell returned to Philadelphia with her family and opened a similar holistic veterinary house-call practice in Mt. Airy. Since that time, she has hired an amazing veterinary technician and her practice has evolved from a holistic consultation practice to an integrative primary care practice, which she finds incredibly rewarding. Dr. Kassell is thrilled to serve the people and pets of metropolitan-area Philadelphia.

Philosophy of care

Dr. Kassell strives to provide top quality veterinary care for dogs and cats–from puppy- and kitten-hood through the “golden” years–in the comfort of their favorite environment, their own homes!

Dr. Kassell’s amazing team

Zoe Osborne, Veterinary Assistant

Zoe is an undergraduate student at the University of Pennsylvania, majoring in Earth Science and Anthropology. She also happens to be Dr. Kassell’s daughter! Zoe has been helping out with the practice in some way or another since she was nine years old, and while vet medicine most likely isn’t in her future, she has absolutely loved taking a more hands-on role assisting Dr. Kassell during the pandemic. Zoe is a big fan of all animals, especially large, silly dogs and any cat that will let her pet it. When she’s not doing schoolwork or cutting kitty claws, Zoe spends her time dancing, leading campus tours, watching Grey’s Anatomy, knitting, and making any vegan recipe she can get her hands on.
