Kiernan had been awarded the £200 to give to a charity of his choice after his two goals against Ebbsfleet live on BT Sport had earned him the Man of the Match award the previous Saturday.
On his choice of where to donate the prize, Kiernan said “Mental health within football is a really big area, there are players out there struggling and places like this can help people talk.
“Everyone has good and bad days and just like your physical wellbeing it is good to look after your mental wellbeing.”
Wellspring are a counselling and training centre in Harrogate who provide affordable psychological support for the community and in particular people in distress.
Sarah James, Therapeutic Lead at Wellspring added “It is brilliant that people local to us know about what we do and want to support the charity.
“We know we can make a difference in the lives of people, but we also know that we need support from local people and businesses to enable us to do that work.
“On World Mental Health Day we are involved in many different events and functions, but really mental health is something that is important for all of us every day all year round not just once a year, though we welcome the exposure the day brings.
“A big thank you to Brendan for raising awareness of our work! We really appreciate it!”
