Waltham Dog Training Staff

Terri Bright, Ph.D., BCBA-D, CAAB, Director of Behavior Services

Dr. Terri Bright earned her Master’s of Science and Doctoral degrees at Simmons College in Applied Behavior Analysis (ABA) with an animal specialty, and she is a Board-Certified Behavior Analyst (BCBA-D). She is also a Certified Applied Animal Behaviorist through (CAAB) the Animal Behavior Society. She teaches Learning and Behavior Analysis at Northeastern University and lectures nationally on the subject of Applied Animal Behavior Analysis. She is the past President of the Applied Animal Behavior Special Interest Group in the Association of Applied Behavior Analysis International (ABAI), and her dissertation research entailed developing a dog behavior assessment and analysis tool that helps to standardize how dog trainers evaluate why problem behaviors happen. She won multiple Marian Breland Bailey awards from ABAI for her research on applied dog behavior analysis, and put many performance and conformation titles on her bull terriers. She is shown here with her MSPCA-adopted dog, Ribbon.

Dr. Bright launched the Training (now Behavior) Department at the MSPCA-Angell’s Boston location in 2007 and it has grown to include Angell West; adding in the classes at Nevins Farm, the MSPCA-Angell Behavior Department has about 100 classes a week! The Department now has three clinical behaviorists and over twenty skilled dog-training instructors.

Her multi-species behavior skills are demonstrated by her research at the MSPCA-Angell, where her volunteer-training program, Safewalk™, was shown to increase adoption rates and decrease injuries to volunteers. It was published in the Journal of Applied Animal Welfare Science.

Dr. Bright is also the founding editor of a new open-source animal behavior publication, called the Journal of Applied Behavior Analysis in Animal Training (

 Susan Conway, CPDT-KA, Behavior Operations Manager

Susan joined the Behavior team at MSPCA-Angell in 2013 and has since earned the Certified Professional Dog Trainer – Knowledge Assessed (CPDT-KA) certification as well as completed a graduate certificate in Applied Behavior Analysis. Susan assists Dr. Bright in her behavior consults, coordinates training classes, and helps to keep the office running smoothly. She earned her Bachelors of Science from Boston University in 1993, where she studied mass communication and psychology. She spent almost a decade working in marketing at Dunkin’ Brands, and received a Masters degree from Emerson College in Integrated Marketing Communication. After switching gears and earning a certificate in Professional Photography at CDIA/BU in 2006, Susan spent several years working as a wedding and portrait photographer, and also began to volunteer at her local shelter photographing the dogs there who were awaiting new homes. This experience led Susan to further explore animal behavior, and she earned a certificate in Canine Behavior and Training from Mount Ida College in 2013. Susan and her husband currently share their home with a Boston Terrier and a Chihuahua mix.

 Aidan Wilkie, CPDT-KA, Training Coordinator

Aidan has been training dogs since 2016, and received her CPDT-KA in 2017. Before working with dogs and their humans, she had a career in Special Education and specialized in working with physically and cognitively disabled children and young adults with severe behavior issues. As a result, the principles of behavior were always of interest to her, and when she adopted her own anxious four-legged side-kick Zoe in 2012, she found herself applying many of the same behavior modification techniques she had used for years in education. Despite her best efforts, however, Aidan quickly realized that in order to truly help Zoe, she would need to learn more. Since that time, she has dedicated her life to learning about dog behavior and helping people better understand their pups. It was a long-term goal of hers to work in the Behavior Department at the MSPCA, where she continues to learn about how we can help our canine companions live fuller, happier and more enriching lives.

Gwen has been a member of the National Association of Canine Scent Work and a Nosework enthusiast since 2011, when she was introduced to Nosework with her first two German Shepherds, Pi & Sylvie. Since then she’s trained and won titles with her next two German Shepherds, Frank and Gaga, and a family member’s Lab, attaining an Elite Division Level 3 title with Frank. She’s built her knowledge of scent detection by attending many classes, workshops and seminars over the past 12 years, learning from a wide variety of instructors including NACSW founder Ron Gaunt, and by observing many different breeds of dogs finding fun and success in Nosework. She has also trained her dogs in competition obedience and has been a member, board member and past president of Charles River Dog Training Club since 2007.

Rebecca is Fear Free certified, an approved AKC CGC Evaluator, and an Official Mentor Trainer for CATCH Canine Trainers Academy.

 Liz Fay, CPDT-KA, Instructor

Liz’s interest in dog behavior began in 2006. Having grown up without much knowledge of the species, she decided to volunteer at a local animal shelter. Liz’s desire to understand how dogs think and how to effectively communicate with them quickly turned into a passion for sharing this information with others. In 2008 Liz began her career with dogs as the Dog Adoption Coordinator for the same shelter she had volunteered with. Liz has since earned her Certified Professional Dog Training certificate (CPDT-KA) and joined MSPCA as a Dog Training Instructor in 2020. Her passion for helping people communicate and bond with dogs continues to fuel her interest in canine behavior. As well as teaching Puppy Play & Learn, Obedience classes and private lessons for MSPCA, she is also currently the Dog Program Manager at an animal shelter in central MA.

 Amy Grossman, CPDT-KA, Instructor

Amy’s interest in dog training began in high school when she took her elderly family dog back to training classes and joined a dog 4H club.

Amy enjoys dog sports in her spare time and currently trials in Flyball and Scentwork. She has also participated in Barn Hunt, Lure Coursing, Agility, Rally and Therapy dog work. Amy is a certified professional dog trainer and earned a Bachelor’s degree in Business. She shares her home with her husband, two daughters and her Shetland Sheepdogs, Odo & Arex
