TLC has chosen each of its staff veterinarians based on their demonstrated academic excellence, training and kind and caring hearts. At TLC, we pride ourselves on the fact that most of our doctors have been employed with us for greater than 5 years, which shows their committment to our clients and patients.

Dr. Maureen Roberts, DVM
Dr. Maureen Roberts, DVM
I grew up in Charlotte, North Carolina and graduated from North Carolina State University College of Veterinary Medicine in 2003. I have an undergraduate biology degree from UNC-Chapel Hill. In 2004, I completed an internship in small animal medicine and surgery at Animal Specialty Group in Los Angeles. I have been with TLC since 2004, and since 2006 I’ve been the resident “vampire,” working the overnight shift from 6 PM to 8 AM. I enjoy running and competing in short-distance triathlons and I’m currently training for my first marathon. I also enjoy reading (and attending the TLC Book Club), knitting, and a Japanese embroidery craft called temari. I hate cooking, but I love to eat! In 2008, I finally admitted I’m a California girl now, and bought a house in Pasadena, where I live with my dogs Laika, Darcy, and Kate.
Dr. Linnaea Scott, DVM
Dr. Linnaea Scott, DVM
Dr. Linnaea Scott graduated from University of Illinois College of Veterinary Medicine in 2002 with honors. Upon graduation, she immediately moved back to the Golden State, and pursued an internship at Sacramento Animal Medical Group in small animal medicine and surgery. Dr. Scott joined the TLC family in 2006. It is a great joy for her to serve the community that she grew up in. She enjoys general practice, surgery, and emergency medicine. She also enjoys mentoring local high school students. “This really is the most fantastic profession, no doubt about it. We are so lucky to combine science, medicine, community service, etc. in a profession that challenges us and inspires us on a daily basis.” In her free time, Dr. Scott enjoys vegan cooking, gardening, and spending time with her wonderful family. Dr. Scott’s dog Ellie (pictured) is a parvo survivor who sometimes donates blood to parvo victims at TLC. Ellie’s a pit bull mix, but the cats of the house keep her in line!
Dr. Valerie Tesauro, DVM
Dr. Valerie Tesauro, DVM
Dr. Tesauro received her veterinary degree from the University of California at Davis in 1994 after completing her undergraduate work in zoology at Cal Poly Pomona. She has been practicing in the San Gabriel Valley since 1994. While predominately a canine and feline medicine practitioner, she also enjoys working with small mammals such as rabbits, rodents, chinchillas and ferrets. Dr. Tesauro moved to California from New York in 1977. After spending eight years haunting the barns at summer camp in Connecticut, she knew that she was destined to work with animals in some capacity. After resigning herself to the fact that eight years of higher education were unavoidable, she forged ahead to become a small animal veterinarian. Dr. Tesauro is an avid baseball fan, and the Los Angeles Dodgers are a source of great joy and disappointment to her at times! Her spare time is spent with her husband Jeff, as well as their toy poodle Rally and Badger, the basic black rescue cat. Other interests include travel, fine food and wine, cooking, hiking and reading. Future plans include golf lessons…
