Meet Our Family

Dr. Holbrook, Diane Holbrook and Dr.Bizier

This is our family.  We have been working together since 2003.  Dr. H and Dr. B are the veterinarians. Diane is our business manager.

When not caring for our patients and our practice our time is filled with bicycle riding, music, gardening, our offspring and our pets!

Deanna Marriott 

Deanna joined our team in 2019 after being a Veterinary Technician student intern from Great Bay Community College. We asked her to stay with us after her internship was over because she was such a perfect fit for our team. She is now a fully Licensed Veterinary Technician. 


She's smart, hard working and positive. 

Deanna is our resident Room Tech and other Triage Nurse, and always has a smile for everyone!
