MARK Neeld's impact has already been felt at Melbourne, with the recruitment of St Kilda high performance manager David Misson and the departure of two assistant coaches.

Demons assistants Scott West and Mark Williams have both left the club, while Misson fills the role of departing fitness manager Joel Hocking.

"I'm thrilled with the appointment. I'm looking forward to working with him," Neeld said of Misson.
 
"He has an outstanding track record and is an outstanding person with a skill set that will add plenty to the Melbourne Football Club."

Melbourne general manager of football Chris Connolly said the decision to part ways with West after three seasons with the Demons was a tough one to make.

"Given the recent appointment of a new senior coach, it was determined that he needed the opportunity to bring in his own people - as Scott was out of contract, a hard decision had to be made. We wish Scott well for his future within the football industry," Connolly said.

West began in a part-time capacity with Melbourne in 2009 after retiring from the Western Bulldogs, where he played 324 games.

He was in charge of the midfield for the past two seasons.

Williams leaves after eight seasons with the Demons as an assistant to Dean Bailey and Neale Daniher before him.

He coached the Demons' VFL team Sandringham from 2004-6 before becoming the club's development coach. He shared midfield coaching duties with West before becoming the club's ball movement coach in 2011.

His playing career included 19 games for Carlton and 14 for Footscray.

"Mark has been a long-serving member of the football department. He is a very admired person at all levels of the club for his acumen and character," Connolly said.

"He leaves with our best wishes, and we thank him for his outstanding contribution over the years."

Hocking leaves the Demons after three seasons and will be replaced as fitness manager by David Misson, who was recruited from St Kilda.

"Joel has taken our strength and conditioning standards to another level over the last three years," Connolly said.

"We thank him for his service, and wish him all the best for his next role."
