Brookside Stud

Brookside Stud was founded and registered in 1979 with the original intent to breed and produce top quality useful Welsh Mountain ponies (Section A’s) for the North American market without losing type.

Sandy Costanzo-O’Brien, founder, owner and manager of the stud, was raised in and around the Isle of Anglesey, North Wales and Liverpool, England. She had the good fortune to have first hand experience of the breeding of useful up-to-height Welsh Mountain ponies which her uncle bred along with an enormous herd of prize Welsh Black cattle. He was in fact also a respected judge in both categories in those days. She obtained for herself, in the process, invaluable lifelong opportunities and experiences. Making the process of learning easier with reference to Welsh ponies, and the comparisons and opinions on the different types within the breed standards more comprehensible. (Source)
