Hogg is the latest addition to an exciting and new-look coaching team at Warriors following the appointment earlier this month of former New Zealand and Wales international Shane Howarth as Backs Coach.
The 43-year-old, who earned five caps for Scotland during his playing career, will be reunited at Warriors with new Director of Rugby Dean Ryan, after the pair successfully worked together at Kingsholm.
Hogg turned to coaching in 2003 after hanging up his boots at Leeds. He started his coaching career with Stuart Lancaster, now the England coach, and Tony Stanger at the Leeds Academy before moving to London Welsh and then a coaching role with Edinburgh. Hogg joined Gloucester in 2006 initially as Academy Manager before taking responsibility for forwards coaching.
Hugely respected by Gloucester's players, coaching team and supporters, Hogg has been a strong foundation and influence at Kingsholm during his seven years. His responsibility included taking temporary charge of Gloucester for the final three games of the 2011/12 season following the departure of Bryan Redpath.
"It is vital we build a strong coaching team and reputation here at Warriors and so I'm delighted to be able to reunite my relationship with Carl Hogg at the Warriors," said Ryan.
"We spent several seasons working closely together at Kingsholm and Carl has played an important and influential role in all that Gloucester Rugby has achieved in recent years. He brings a level of expertise and detail which will enhance Worcester Warriors and all that we do going forward.
"The combination of Shane Howarth and Carl Hogg is an exciting one and they will complement each other extremely well. I know Carl is excited by this opportunity in his career and we are looking forward to the 2013/14 season and the challenges ahead."
