Our Team

Meet our senior leadership staff

Our staff is full of dedicated, caring people who go above and beyond every single day to help the pets and people in our community. We are thrilled to introduce you to our Senior Leadership team!

Diana Cannon, Chief Development Officer

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.

Alan Clark, Chief Financial Officer

Alan "Al" Clark joined the Humane Society of Southern Arizona in March 2018. Al and his entire family have always been engaged with animals; as children in Texas and Minnesota and in his adult life in Texas and overseas. All of Al’s animals, except that one irresistible golden retriever, have come from shelters. Al came to Tucson in 2014 thinking he might retire but soon realized he wanted to be engaged in a work activity that kept him involved with his new community. Having worked primarily in corporate, academic and economic development arenas, it was time for a mission closer to his heart.

While living in Morocco, Al experienced first-hand the impact of culture, education, and economics on animals and realized for the first time how much work is needed to care for our animals and nurture the blessings they bring to us all. One of the most admirable persons he has ever met was a devoted veterinarian who treated Al’s traveling cats and dog and who struggled to bring animal care to the poverty of inner-city Fez. This experience and many more have left a continuing compassion in Al for the world of animals.

He is married to his high school sweetheart, Susan; after 40 years apart, they reunited and enjoy spending their spare time between Tucson, Oregon, Texas and Minnesota sharing music, outdoor activities and continuous learning with family, friends and their two Maltese.

Pat Brayer, Clinic Director

Pat Brayer is HSSA’s Clinic Director. Pat comes with an in-depth and comprehensive background in animal care and animal welfare. Pat has served as the President of the Board and shelter director of the San Gabriel Valley Humane Society. She has also served as the director of the Palm Springs Animal Shelter. Pat knows first-hand about working with a community to control animal overpopulation, making great strides with the Coachella Valley community to provide affordable spay/neuter and vaccination programs.

In her spare time, Pat enjoys NASCAR, interior design, reading and writing and is currently working on her first book. Pat also enjoys the company of her cats, Toby, Punkin Ballerina, Meechi and Tuffy.

Lisa Gagnon, Human Resources Director

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.

Christian Gonzalez, Director of Operations

Christian Gonzalez is HSSA’s Director of Operations, dedicated to the sheltering and placement of the thousands of pets that enter HSSA’s facility each year. In his 12 years of service, which started as a kennel technician, he has been an advocate for implementing new programs and creating a holistic approach to animal care.

Growing up on the Arizona/Mexico border, Christian knows all too well the number of stray and unwanted pets in our Southern Arizona communities. As a young boy, he would sneak injured and homeless pets into his bedroom and nurse them back to health. In his current role as Animal Services Director, he has been a driving force over the past 16 months to help find better ways to care for the pets needing temporary shelter. His tireless efforts have helped 95 percent of the animals entering our facility find new homes or alternative placement.

In his spare time, Christian displays great talent in the kitchen. However, his other true passion is spending his time caring for and rescuing reptiles. He has been involved in the rescue and placement of hundreds of reptiles nationwide.
