Swan’s A Swimmin’
Mobile Veterinary Services

Making waves in mobile vet care!

Swan’s a Swimmin’ Mobile Veterinary Services was founded by Dr. Marissa Swan to bring compassionate, accessible veterinary care directly to pets and their families throughout Spring, TX and surrounding Greater Houston communities. What began as a mission to help pet owners facing transportation barriers has grown into a flexible mobile practice serving homes, senior communities, rescues, community animal caretakers, and local pet-centered businesses. Dr. Swan believes every pet and every family deserves individualized care that is realistic, compassionate, and tailored to their unique needs—whether that means gold-standard treatment or a comfort-focused approach that prioritizes quality of life.

We serve a 20-mile radius around Spring. If your location falls outside that area, we can often travel further for an additional fee. Not sure whether we come to your area? Contact us and we’ll confirm availability and pricing. Please be aware that in an effort to keep our prices as low as possible, we do not work with traditional office staff. Phone calls are returned within 24 business hours. Please text, email, or complete the booking form for the quickest response.
