Sundgren was born in Vammala, Finland, but moved to Sweden with his parents as a toddler, being raised in Västerås. There he was often called Gary and it caught on; for the duration of his career he was always called by it, instead of his birthname.
Sundgren started playing professionally with AIK Fotboll, being an undisputed starter from an early age. He scored the winner against Malmö FF when AIK became Swedish champions for the first time in 55 years, in 1992.
