Tara also created and ran large-scale donor trips to further embed support and opportunities for engagement. She created Spayathon for Puerto Rico, a post-disaster recovery program, that provided free sterilization and vaccinations to over 56,00o animals. This effort is the largest of its kind in history for mass sterilization, and animal welfare coalition work across the globe. This effort also garnered recognition as a Clinton Global Initiative Program, and paved the way for the largest study done to date on the efficacy of high-quality, high-volume spay/neuter efforts, showing the impact and effectiveness of this work to decrease suffering and needless euthanasia. When Covid-19 hit, Tara ignited 30 national organizations to rally and raised millions to help shelters and rescues with funding, training, and supplies.

Susan Rosenberg
Senior Director, Pet Programs (Animal Medical)
Meet Susan

You may know Susan from Petco and Petco Foundation, where Susan spent almost 16 years. Her passion for animals was discovered at a very young age when their neighbor reported to her mother that little 8 year old Susan was creating her own zoo in the family’s backyard. When her mother went out to investigate, she found that Susan was carefully taking care of many unwanted and abandoned neighborhood animals with her weekly allowance. She even rescued a few that didn’t really need it, so her mother promptly returned their neighbor’s cat stating that ‘Susan really doesn’t like cats to be left outside by their family so she took yours.’ A life in animal welfare was her destiny.

Spending eight years working side by side with Paul Jolly, Petco Foundation Executive Director (retired), Susan learned an instrumental lesson for passion, hard work, dedication and a “get it done” work ethic. Working tirelessly to make a difference is what you will always hear about Susan, which is why we just had to get her on our team. Susan prides herself as being able to give funding away as fast as it can be raised. A popular public speaker, FEMA certified, Ready San Diego Sector Chair, marathon shoe shopper, CA Humane Academy graduate, fundraising award winner and an expert in handling disaster events that include animals, Susan manages several exciting and rewarding programs.

She previously worked as the Finance Manager for International Studies Association (Non Profit), an academic organization that worked to connect political scientists around the world. Her experience in international development work includes the creation of an impact assessment for a uniquely modeled entrepreneurship & leadership institute in Benin, West Africa.

Brittany holds a certification in social impact investing from the Monterey Institute for International Studies for her ability to understand and more appropriately evaluate the true effectiveness of investments on effected livelihoods and communities. Additionally, her experience as an investment analyst advisor for the Global Alliance for Clean Cookstoves expanded her understanding of the importance of increasing awareness and demand for the use of clean cookstoves in developing countries, as it relates to the environment, fossil fuel use and health (especially for women and children).

Kimberly Spina
Manager, Pet Programs (Foster)
Meet Kimberly

An animal lover to the max. In fact, if you ever can’t find her during a Rescue Rebuild build, go check the cat room. Chances are, you will find her there. At every shelter that Rescue Rebuild renovates, she plays this fun game where she finds a dog that she wants to take home and vows that if it hasn’t found a furever family by the time the build is over, she will fill out the adoption papers herself. Luckily, for her own sake and the sanity of her roommate, this has worked out in her favor so far. Learning all the tools, toys, and construction projects as she goes, she has already become the expert at chain link and is the only one in the group who is allowed to teach the volunteers!

Coordinator, Pet Programs (Rescue Bank)
Meet Sharon

I got my start in animal welfare at the age of 18 working as an Animal Control Officer and Cruelty Investigator for an animal shelter in New Jersey. Five years later I resigned from the shelter when I accepted a position with Petfinder, where I remained for the next 10 years. Following my years at Petfinder, I owned and operated my own pet sitting and dog walking company. In 2019, my husband and I decided to move from Pennsylvania to Idaho with our two dogs in search of more accessible outdoor spaces. After a couple of years, I am thrilled to be back working for the animals on the Rescue Bank program at Greater Good Charities!
