StaffWe hope to be your choice for veterinary services in Marietta!

Our hospital opened its doors in 1968 and was founded by Dr. Michael Mason. Dr. Jerry Diaz purchased the practice in 1999. Dr. Diaz and his veterinary team make patient care and client service the top priorities of the hospital. A few members of our staff are Spanish speaking including Dr. Diaz.
