He made his first team breakthrough in 2009-10, a season which saw him represent England in the U20s Six Nations and Junior World Cup in Argentina.
The following season saw him start to feature more regularly at first team level, and he quickly showed an ability to make the try line on a regular basis.
Capable of playing centre, wing or full back, the 22 year old enjoyed a real breakthrough campaign in 2011-12, when he started 22 matches and scored 10 tries.
He also won the LV= Breakthrough Player and Aviva Premiership Player of the Month for January awards.
His development was duly noticed by the England selectors, as he was capped at Saxons level and then called up to link up with the England senior squad on their summer tour of South Africa.
Gloucester Rugby are, of course, looking to keep together one of the most talented, young, predominantly English backlines in the Aviva Premiership, and Director of Rugby Nigel Davies is delighted to secure May's services.
"I've spent a lot of time in recent weeks working on retaining a number of our key players, and I'm delighted to be able to confirm that Jonny has signed a new contract.
"Jonny has so much talent. He's already achieved a lot with Gloucester Rugby, but he's got so much potential that I genuinely think that we've only just scratched the surface of what he can achieve.
"It's great news for the club that he's committed his future to us. He's spent his whole career at Gloucester, and is happy with the direction we're heading in.
"We want to keep this core group of players together as there's a bright future ahead."
