Serving shelters and veterinary professionals across the US and Canada
What We Do
We offer flexible, scalable services tailored to the needs of individual shelters and communities. From one-time support to long-term implementation, we help shelters operate more efficiently, improve animal outcomes, and meet the evolving challenges of today’s sheltering environment.

HQHVSN Training for Veterinarians and Technicians
We offer hands-on, in-person training to help veterinarians and veterinary technicians build or refine their high-volume surgical skills. Whether you’re onboarding new staff or expanding your clinic’s capacity, our training programs are practical, efficient, and built for real-world shelter settings.

Shelter Operations Consulting
Our consulting services go beyond recommendations – we stay with you through implementation. Each consultation begins with an assessment of current operations, followed by clear recommendations, staff training, and hands-on support to ensure new systems are effectively adopted. Areas of focus include:
We don’t just hand over a report and walk away. We work alongside your team to ensure sustainable, real-world results.

Shelter Veterinarian and Technician Recruitment
Finding and retaining qualified veterinary professionals is one of the biggest challenges facing animal shelters today. We offer targeted recruitment services to help you identify, screen, and onboard DVMs and technicians with the right experience and mindset for the shelter environment. Our approach is hands-on, efficient, and grounded in a deep understanding of shelter operations.

TNVR Program Development
Whether you’re starting from scratch or refining an existing program, we can help you design or optimize Trap-Neuter-Vaccinate-Return (TNVR) strategies that are effective, community-supported, and legally compliant. Our services include protocol development, staff training, public communication guidance, and implementation support.

High-Quality, High-Volume Spay/Neuter (HQHVSN) Clinics
We provide experienced surgical teams – including veterinarians and anesthesia technicians,, – to perform high-quality, high-volume spay/neuter services on-site at your facility during off-hours. Our weekend and evening clinics help shelters clear backlogs without interrupting daily operations or stretching internal staff.

S3 offers per diem and relief veterinarians and technicians to support your shelter’s operations when staffing gaps arise. Whether you need short-term coverage, ongoing supplemental support, or temporary placements during recruiting transitions, our team members are shelter-ready, mission-driven, and equipped to step in with minimal onboarding.
