Mr Costa has volunteered with the PCYC for about 25 years.
The former gymnast who specialised in rings, high bar and the parallel bars started coaching when his three daughters took up the sport and joined the PCYC soon after.
‘I was the first male (gym) coach in 13 years,’ Mr Costa said.
He coached at Scarborough and Balga PCYCs before deciding to retire but was convinced to stall his retirement and coach at Claremont in 1995.
‘I like being able to do my own thing without being pushed to get the kids to meet timelines on their skills,’ Mr Costa said.
‘They are here to have fun and have a social life.
‘I want to make gymnastics successful here (at Subiaco).’
First stop is winning the JB Stratton Cup which Claremont has won on three consecutive occasions.
‘I want Subiaco to be the most successful club going,’ Mr Costa said.
Gymnastics is held at the Subiaco PCYC on Tuesdays, Fridays and Saturdays and caters for people aged 12-25.
Wrestling and boxing classes previously held at Claremont have transferred to Subiaco.
