Our Volunteers

Amanda Fuller, KPA-CTP, CTDI, Certified Fear Free Professional


Keller's Cause Founder Amanda Fuller couldn't help but fall in love with double merle dogs after bringing Keller in to her life. 

Amanda has dedicated her free time to teaching the public about double merles, and how to live with a special needs dog. Her love for animals is present in all aspects of her life as she works full time as a Fear Free Certified veterinary technician. She is also a graduate of the Karen Pryor Academy (KPA) and is a Certified Trick Dog Instructor (CTDI).

When she isn't working, doing educational events, or rescuing dogs, she spends all her time with her dogs Canon, Kai, Calamity, and Keller. They enjoy playing, hiking, and competing in agility, rally obedience, and other various events.

Rose Adler, CPDT-KA, CTDI


Acting as our resident designer, video editor, and co-founder, Rose has helped get Keller's Cause off the ground.

Rose works as a full-time Multimedia Developer, but when she isn't working, doing educational events, or rescuing dogs, she spends her time with her dogs, Pixel, Braille, and Wink, hiking, kayaking, training, and doing photography.

Rose has taken her interest in behavior modification and is currently attending Jean Donaldson's Academy for Dog Trainers, working towards her Certification in Training and Counseling. She has recently completed her Certified Professional Dog Trainer - Knowledge Assessed (CPDT-KA) certification through the Certification Council for Professional Dog Trainers, Inc.

Alyssa Lehman


Alyssa is in charge of our marketing and media communications. She lives among the apple orchards of Adams County, PA with her ever-growing herd of rescues: Australian shepherd Barnes (double merle), Siberian husky Booner and multiple cats.

A graduate of Penn State University, Alyssa worked in the communications field for several years but has recently decided to go back to school in pursuit of a new career.


Her free time is spent volunteering for local rescues, doing artsy stuff and operating a small petsitting/dog walking business.
