Rotherham-born Matt, is no stranger to the Millers, previously lining up against them for Macclesfield Town and Notts County in recent years, as well as being in opposition at Don Valley and Millmoor for Mansfield Town and of course Sheffield Wednesday.
However, what people may not realise is that whilst he’s been a thorn in the side of the Millers on the field, he had been working with his hometown club as a part-time coach with various youth teams.
After his contract with Macclesfield Town ran out in the summer of 2012, Matt made the switch into full-time coaching with the Millers, whilst continuing to play in the Evo-Stick League for Stocksbridge Park Steels.
Taking on the role of Development Phase Lead Coach he oversaw the development of the 12-16 year old's at New York, whilst also coaching youngsters at Thomas Rotherham College.
In the close season of 2015 he stepped up to the role of Head of Academy Coaching.
Following Paul Warne's appointment as interim manager upon the departure of Kenny Jackett, Hamshaw was given the role of interim assistant as he stepped in to the first team fold.
After the announcement that Warne would continue as the temporary boss until the end of the season, it was confirmed that the Rotherham-born coach would continue to assist for the remainder of the 2016/17 campaign.
Hamshaw was part of the staff that earned promotion to The Championship via the League One Play-offs, whilst he was instrumental in blooding a host of youngsters includuing midfielder Ben Wiles.
