Dr. Amanda Olsen knew she wanted to be a veterinarian at the age of 5, and shadowing her local veterinarian during surgery at the age of 11 solidified her passion. A graduate of Ross University School of Veterinary Medicine with clinical training at Texas A&M, Dr. Olson is particularly interested in surgery, preventative medicine, and dentistry. Dr. Olson’s favorite part of being a veterinarian is building lasting relationships with both pets and their families. When she's not at the hospital, you'll find her baking, catching Broadway shows, or at home with her two dogs: Butternut (a rescue from Nevis who loves strawberries) and Dart, her golden retriever who's obsessed with fetch. Dr. Jason Chin knew he wanted to be a veterinarian as early as third grade, when he wrote it down as his dream career after years of caring for stray cats and being inspired by nature shows. After earning his B.A. in Economics with minors in Math and Computer Science from Hunter College and spending several years in banking, he pursued his true calling at Ross University School of Veterinary Medicine, graduating in 2013 with honors. His professional interests include surgery, internal medicine and cardiology, ultrasound, dentistry, and urgent care, and he is an active member of the NYS Veterinary Medical Society, Westchester Rockland Veterinary Medical Association, and AVMA. For Dr. Chin, the most meaningful part of being a veterinarian is advocating for the health and wellbeing of pets while connecting with families to find the best possible way to meet their pet’s needs. Having grown up just across the street from where Roots Veterinary Hospital now stands, Dr. Chin has deep ties to Tappan. Building a practice here is his way of giving back to the community that shaped him. At home, he and his wife enjoy life in Tappan with their two children and three pets—Mazie the mixed breed dog, Simone the lop-eared rabbit, and Luna the tabby cat—while he also makes time for CrossFit, running, soccer, golf, music, and traveling. Marissa has worked in the veterinary field for over 16 years and is one of the proud founders of Roots Veterinary Hospital. Her love for animals began in childhood and blossomed into a lifelong career devoted to pet care and client support. At home, she’s a devoted pet parent to Spirit, a black Labrador; Logan, a majestic long-haired cat; and Sawyer, a sweet orange cat. Outside of work, she’s always on the hunt for her next adventure—whether hiking, paddleboarding, or exploring the outdoors. Marissa thrives on the artistic side of life, bringing warmth, experience, and creative energy to everything she does.Our Doctors
