Noreen Durkin


Noreen moved from the US to Antigua with her husband Luis Velasquez in 2018. Wanting to give back to the community, she began volunteering in our mobile sterilization clinics, monitoring the cats during recovery. She does a stellar job of this and has generalized to helping in many different areas on clinic days. We are very grateful to have her on our team.

Luis Velasquez


Luis and his wife Noreen have been living in Antigua since 2018. Luis began volunteering at clinics alongside Noreen in 2022 after seeing the profound effect that our clinics have in local communities. Luis was instrumental in connecting us to his home town of Comalapa where the free-roaming dog and cat population is far too large. Luis helps facilitate clinics by connecting with the local authorities and churches. He has also completed construction of a small veterinary clinic in a nearby community, with the aim pf providing affordable veterinary services to those who most need them. He has become an integral member of our team on the ground in Guatemala.

Cat moved to Guatemala from the UK in 2020. She became a volunteer for us after rescuing her fearful dog Leo, who she learnt a lot about training and force free behaviour modification through. Cat has been running sterilisation clinics since 2022, making key connections in the community and expanding the areas that we cover. She also carries out many other operational tasks, ensuring past and present animals get the ongoing care they require.

Cat loves learning about dog behaviour and the medical side of animal care, and she spends as much time as possible hiking in the local mountains and fincas.

Flori is from El Salvador but lived in the USA since 1994. She has been married to John Batt for 33 years and has 2 amazing children, Alejandro and Sofia. After becoming empty nesters the couple decided to move to Antigua with their 3 dogs. They now also have adopted 2 kitties. Flori has been living in Antigua for 2 years now and she works tirelessly to capture, transport, and return the free roaming dogs we sterilize. No task is too small or too big for Flori to offer to lend a hand.

Jimmy Mattrell


Jimmy is a big animal lover. He was born and raised in Guatemala, and has several businesses including Union Cafe. During the pandemic he approached us to ask for help sterilizing dogs and cats in a desperately poor village called Guayabal very close to Antigua. We obliged, and Jimmy has been volunteering at clinics whenever his schedule allows every since. He also generously provides delicious sandwich lunches from Union Cafe to our dedicated volunteer and medical team on clinic days.

Lead veterinarians Doctor Andrea Merida, Doctor Andrea Ramirez, and Doctor Francisco head up our skilled veterinary team. They are specialty trained in high volume microsurgery techniques and have performed tens of thousands of successful sterilizations between them. They travel to each clinic and bring several technicians, a tattooist, and support staff along with them. Their skill, expertise and enthusiasm make our clinics the astounding success they are and are at the core of what we do.
