Together, we will continue to build an inclusive culture that encourages, supports, and celebrates the diverse voices of our HSSA team and the communities we serve.
Diana Cannon has never spent a day of her life without a dog. A Michigan native, she grew up in a family that loved and valued their pets as members of the family. Beagles were her father’s dog of choice until one day Diana asked if she could have a dog of her very own. Her parents took her to the humane society and there she found and adopted her childhood friend “Penny.” For 14 years, until Diana left for college, Penny was her constant companion.
Diana is a longtime resident of Tucson and deeply involved in the affairs of the Tucson community through her career and volunteer involvement. She has extensive experience in business development in both corporate and nonprofit. She holds a Bachelor of Science degree from Western Michigan University and numerous accreditations in sales management and leadership. Diana has a strong sense of volunteerism and has been involved in a variety of Tucson nonprofit organizations over the past 25 years.
Diana believes that pets teach us humanity: “They give us their absolute all and we owe them love, faith, and trust.”
Diana and her husband have three miniature dachshunds – Daphne, Dottie, and Dixie – and have since adopted Dory, DD, and Darby from the Humane Society of Southern Arizona.
Lisa Gagnon is the HSSA Human Resources Director. Since she was little, all Lisa Gagnon wanted to do was work around animals. She was the one who brought home strays and begged her parents to keep them! She went to junior college for a couple of years but could never find anything she wanted to commit to. She was working at a martial arts school in 1986 when the opportunity for a part-time, temporary position came from a student’s mother to work at the Humane Society of Tucson. Yes, back then the name was a little different.
She started in a position in the bookkeeping department, which after three months turned into a full-time
permanent position in the shelter. Over the next 11 years, Lisa worked in many capacities including Shelter Technician, Clinic Technician, and Assistant Shelter Manager. In 1997, she became the first Training Coordinator for the HSSA. In 2001, Lisa was offered the position of Director of Human Resources. She runs the maze of employment law, employee benefits and training to keep all our employees safe and happy!
Lisa’s home is filled with four dogs - all from the Humane Society of Southern Arizona.
