How it works

Two hundred animals. Three days. Anywhere.

M.A.S.H. is a precise and efficient system, refined over two decades of field operations across several countries. Our field teams are currently operating at full capacity, but we can help you learn how to host M.A.S.H. clinics in your community through our consultation services.

What partners say

Built with trust in our partnerships with local organizations and proven in those communities.

In 2025, we added Animal Balance as the next "building block" to our services. We were originally thinking 1,000 ADDITIONAL spay/neuters would be a fantastic 'jump start' to address the need in Lake County. What we didn't anticipate was the education on streamlining procedures, both surgically and for the support staff. The real surprise was the staff & volunteer excitement to be part of such an event. Several of our key staff have signed up to work with Animal Balance clinics in other locations. We have made connections with new vets and surgical staff who will be joining OUR clinics in 2026, and we signed up many new high-quality volunteers. These connections will allow us to offer more s/n surgeries in the same four-day footprint we currently have."

Nancy Johnson

President of SPCA of Lake County

I am so thankful for Animal Balance coming to our rescue here in Shasta County. Our shelter has been over capacity for many years, and as a result, our veterinary team has had their hands full caring for the animals already in our care. This leaves very few open spots to assist the public with daily spay and neuter surgeries. Animal Balance has been a blessing to our community, altering 600 plus animals over a span of only 3 months; we are only capable of spaying and neutering 100–150 animals in that same amount of time. What impressed me the most about the Animal Balance team is how they bring together a large group of people—many volunteers, and many meeting each other for the first time—from all over the country and from different walks of life. Then, like magic, all of these people begin working together seamlessly. It’s like watching a school of fish move with grace, even while handling the stress of caring for 65–70 animals a day. There are an average of 30 people working together at all times. Each animal is treated with care from the moment it is checked in to surgical induction, monitoring, recovery, and finally the moment it walks out the front door. Our volunteers were excited to work in a different department, meet new people, and learn new skills. The entire event was well organized and had an excellent flow, making a positive impact on our staff, our volunteers, the animals, and the families in our community."

Dr. Kristin Campbell

Medical Director of Haven Humane Society

Working with Animal Balance for the last 2 years in Santa Cruz County, CA has been truly remarkable. Their fearlessness, professionalism, and commitment to truly collaborative, respectful, and compassionate preventive health service is contagious and inspiring. We finish each clinic a bit exhausted, but also deeply gratified, knowing we've helped hundreds of families make the key investments of sterilization, vaccination, and microchipping for their beloved companions, and prevented thousands of potential future intakes at our shelter. Animal Balance makes the challenging experience of hosting a 3-day HQHV clinic joyful, compassionate and welcoming for staff, volunteers, pet owners, AND pets!"

Questions

Frequently asked questions.

What kind of space do we need?

Any large indoor space works. A gymnasium, a warehouse, a shelter facility, or a community center. We need enough room for surgical stations, recovery areas, and intake. Our team will assess your space during the planning process.

How many animals can you sterilize per clinic?

Each three-day M.A.S.H. deployment performs a minimum of 200 surgeries. For communities with higher need, multiple consecutive or recurring clinics can be scheduled.

What animals do you sterilize?

Dogs and cats. Both owned pets and community animals are accepted. We work with your organization to determine the best mix for your community's specific needs.

Is M.A.S.H. clinically safe?

Yes. M.A.S.H. uses the same anesthetic protocols, sterile surgical standards, and post-operative monitoring as permanent veterinary clinics. Our Medical Director oversees all clinical protocols across every deployment. M.A.S.H.is not a shortcut, it is a fully standardized clinical system.

Can our organization learn to run M.A.S.H. independently?

Yes. Our consultation services are designed to give organizations everything they need to replicate the model.

How does M.A.S.H. relate to AB 2010 in California?

AB 2010, currently advancing through the California legislature, would remove a regulatory barrier that has historically limited M.A.S.H.-style operations in the state. Animal Balance has been central to the field evidence behind the bill. If passed, it will significantly expand the scale at which M.A.S.H. can operate across California.

I'm a veterinarian. Can I join a M.A.S.H. deployment?

Yes. We're always looking for experienced veterinarians and technicians to join our team. Work as Vet ➝
