Veterinarios Internacionales Dedicados a Animales Sanos
International Veterinarians Dedicated to Animal Health

ViDAS is a non-profit organization that assembles teams of veterinarians, veterinary technicians, veterinary students, and animal–loving volunteers to travel internationally and provide free spay and neuter services for dogs and cats. Our mission is to provide these services in areas of need as a means of combating pet overpopulation. We strive to work together with the local community to provide education to people and aid to local veterinary groups to spark positive and sustainable change.

Our Current Missions

Rosebud Reservation

ViDAS is excited to announce that we will be collaborating with the Lakota Sioux on the Rosebud Reservation at their future veterinary clinic, Wamakanskan Wawokiye Oti -- Helping Animal Clinic! This amazing initiative, the inspiration of Kathleen WoodenKnife, will help thousands of dogs, cats and horses on the reservation where there were previously very limited veterinary services. We are working hard to help them create a sustainable program for years to come!


The Spayathon for Puerto Rico

The Spayathon for Puerto Rico is a coalition of 26 organizations that have been brought together by the Humane Society of the United States to champion an island-wide spay and neuter campaign in Puerto Rico. As a collective group, we were able to safely spay and neuter over 30,000 dogs and cats through four free, high-quality, high-volume spay and neuter clinics held between June 2018 and February 2020. Unfortunately, due to COVID-19 ViDAS has not been able to safely participate in further Spayathon for Puerto Rico clinics. 

Round 1 – June 3-9, 2018 (5,294 animals safely spayed/neutered and vaccinated)

Round 2 – November 3-9, 2018 (7,722 animals safely spayed/neutered and vaccinated)

Round 3 – February 3-9, 2019 (8,428 animals safely spayed/neutered and vaccinated)

Round 4 – May 3-9, 2019 (8,644 animals safely spayed/neutered and vaccinated)

Round 5 – November 2-7, 2019 (7,194 animals safely spayed/neutered and vaccinated)

Round 6 – February 21-26, 2020 (8,298 animals safely spayed/neutered and vaccinated)

Learn Who We Are

  • Ruth Parkin
    President & Chair

    Veterinarian – Self-Employed
    Vancouver, Washington
    Board Member Since 2002

    Ruth grew up on a small family farm in Washington State. She graduated from Colorado State University College of Veterinary Medicine in 2005, and fell in love with Colorado. After working as a small animal veterinarian in Denver for several years, she recently moved back to Washington State to be closer to her family. “I participated in my first spay/neuter clinic in Playa del Carmen during the summer of 2002 – I was in my second year of vet school at the time. We had a successful clinic, but there was obviously so much more to be done. The streets in the area were covered with sick, starving animals – a direct result of pet overpopulation and lack of resources to adequately address it. We recognized the need for a sustained presence and vowed to provide as much as we could. Four of us, all classmates at CSU, founded ViDAS that same year and have been working hard toward our cause ever since, sending down several crews a year to do high volume sterilization clinics while keeping our medical and safety standards as high as those used in clinics in the US. We are seeing changes and know that our approach is working! I am so proud of ViDAS, our crews, volunteers and our accomplishments so far and know that we will continue to do great things! Working with ViDAS has been one of the most rewarding experiences in my life, and I look forward to working with our great vets, students and volunteers year after year. Thanks everyone for all your hard work!'

    It was through her friendship and working with Ruth that Kristine came to ViDAS. In August of 2014, she went on her first trip as a vet tech/photographer and really enjoyed the experience. The people, the crew, the community, the dogs, the hard work … all of it equally amazing and wonderful. She looks forward to being able to attend and support future ViDAS trips.

  • Katie Redd

    DVM Candidate 2021 – Colorado State University
    Fort Collins, Colorado
    Board Member Since 2017

    Katie Redd is a Colorado native who has always had a love for animals and a passion for science and medicine. While working as a veterinary technician at a local cat rescue’s spay and neuter clinic after earning her BS from Colorado State University, she discovered her passion for helping care for homeless pets and helping every animal receive the veterinary care they need. After hearing about the amazing work ViDAS does, she went on her first trip in the summer of 2017 and became very passionate about the incredible work done at the clinics. Seeing the number of people and animals that ViDAS can help in just a few days was astounding and inspiring.

    As she earns her DVM degree at Colorado State University over the next 4 years, she hopes to go on many more ViDAS trips and help inspire other students to volunteer their veterinary skills toward helping the animals that need it most. When Katie isn’t busy working toward earning her DVM, she loves to travel, sing and play music, hike, paint, and cuddle her three cats Milo, Pepper, and Mira.

    Travis’ first ViDAS experience took place shortly after completing his undergraduate studies in 2009. Since then, Travis has attended over a dozen ViDAS clinics and his involvement in the organization has grown steadily over time. The positive impact each ViDAS clinic can have on the surrounding community and the extremely high quality of care provided to each individual animal during a campaign are just two of the many reasons that keep him coming back for more.
