Our Volunteers

Amanda Fuller, KPA, CTDI


Amanda is the reason this all exists. She couldn't help but fall in love with these 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 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 playing, hiking, and competing in agility, rally obedience, and other various events.

Rose Adler, CTDI


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


Rose works as a full-time Online Learning Senior Multimedia Developer. When she isn't working, doing educational events, or doing rescue, 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 CTC and CPDT certifications.

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.

Chelsea & David Kemmer

Always embracing any task we throw at them, Chelsea and David are invaluable members of our volunteer team, acting in whatever roll we need them for on a given day!


Despite working full time and wrangling their own pack of dogs (and pigs!), Chelsea and David have been an amazing addition to our organization.


Aside from helping at educational events and helping to process foster and adoption applications, these two are always willing to take in foster dogs of any age, disability, or behavior problem. We are so happy to have them join us on at the forefront of the fight against irresponsible breeding!
