Performance Doorset Solutions, based in Littleborough, have raised over £4,000 for Springhill Hospice.
Twelve members of staff completed the Yorkshire Three Peaks on 4 September, raising £4,075 for the hospice.
Those who took part were: Peter Dawson; Esther Dawson; Kev Barnes; Ben Davies; Helen Tattersall; Aidie Butler; John McGrath; Tracy Mills; Nico Blackburn; Drew Keane; Charlotte Larkin; and Kris Keane.
The challenge itself involved a 39km circular trek across the iconic Yorkshire Dale mountains of Pen-y-Ghent, Whernside and Ingleborough, with heights along the route reaching up to 1,585m.
The climb took the team between 8.5 hours and 12 hours to complete.
