Dennis Barros, Dvm

Meet Dr. Dennis Barros

 

Dr. Dennis Barros graduated with honors from the prestigious Colorado State University and brings more than 30 years of experience in veterinary surgery, medicine, and hospital leadership. Throughout his career, he has earned a reputation for successfully managing complex surgical cases while providing compassionate, high-quality care for companion animals.

 

Dr. Barros lives in South Maui with his partner and two children. Outside of the hospital, he enjoys spending time with his family, swimming in the ocean, fishing, and experiencing everything Maui has to offer.

 

Beginning in August 2026, Dr. Barros has dedicated his practice exclusively to surgery. He serves as the Chief of Staff and lead surgeon at Animal Care & Wellness Center, where he partners closely with your primary veterinarian to provide advanced surgical care. His goal is to offer many specialty procedures locally, allowing pets to receive exceptional care without the need to travel off-island whenever possible.

 

Dr. Barros is passionate about helping pets with conditions that require advanced surgical expertise. His extensive experience includes orthopedic surgery, advanced soft tissue surgery, neurologic surgery, reconstructive surgery, oncology, emergency surgery, and abdominal and cardiac ultrasound.

 

His dedication to his patients is also deeply personal. When his own dog, Biscuit, became paralyzed due to a spinal disc injury, Dr. Barros performed the spinal decompression surgery himself. Biscuit made a complete recovery and now runs, plays, and enjoys life again. Experiences like this reinforce Dr. Barros' commitment to restoring mobility, relieving pain, and improving the quality of life for every patient he treats.
