Mitchell has lifted the Midlands and South West Football League Trust Every Player Counts prize after an incredible year for the 16-year-old, who plays for the junior deaf team Cardiff City has created as part of the Every Player Counts programme.
His national award comes just a couple of months after Mitchell starred for Cardiff City's Under-16 squad, who were crowned champions at the National Deaf Children's Society's football tournaments in Reading and Liverpool.
Mitchell said: "I'll never forget 2012, winning the tournaments and then getting this award - it is very special indeed."
Mitchell also plays for his local amateur football club Heol Hir FC, who play in the Cardiff and District League, and a school team at Llanishen High.
"I have always supported Cardiff City and feel very privileged to be a member of the squad," added Mitchell.
"The coaches at Cardiff City are always friendly and enthusiastic and make the sessions very enjoyable to attend by all players and all abilities.
"I'd also like to say thank-you to my parents for all their support."
Mitchell's mum Jo said: "We are so incredibly proud of him winning this award.
"He is tremendously dedicated, training four times a week and also does volunteer work with Cardiff's disability squad."
His coaches at Cardiff were impressed by his maturity, and his commitment to help others, as well as overcoming the communication challenges that he faces with a huge amount of determination and has impressed all those who have watched and coached him.
In addition, Mitchell supports fellow members of the squad by providing support, extra demonstrations and acts as a mentor.
Mitchell added: "Since starting with Cardiff City I have enjoyed the training sessions with all the participants and meet new friends from different areas that I would not have met in other circumstances."
Every Player Counts, a leading project of The Football League Trust, is supported by The Football Pools who donated £2.59 million to the project.
The scheme now includes 48 Football League clubs, which are growing disability sports provision across England and Wales
Mike Evans, General Manager of The Football League Trust, said: "Mitchell has made light of his situation to achieve so much on the pitch this season. But it is his dedication to help others, and volunteering his time to coach that really made Mitchell's story stand out and we are delighted for him to pick up this well deserved award."
