“Vision and action are his strong suit”

To whom it may concern, It is my pleasure to write to you to recommend Mateusz as someone of resilience, creativity and leadership with a great skill and passion for Marketing.

I myself am a qualified Marketing professional with over 13 years of experience in Marketing and E-Commerce for some of the UK’s leading retailers, including the hiring and building of Marketing teams.

I have known Mateusz for around 4 years now and have had the honour of leading and supporting him and his family through life as part of our church. This has included witnessing him set up and lead youth ministry for 11-18 year olds where I saw how he mentored, challenged and grew young people and formed, led and organised a team of volunteers to do the same. The young people and teams involved continue to hold Mateusz in the highest regard.

Mateusz is a visionary leader, able to enthuse those around him whilst also connecting at a personal level, pastoring them with a high level of emotional intelligence. In addition, Mateusz and I have shared many great conversations about his previous experience in Marketing and Sales and I have reviewed and advised on many aspects of his work, owing to my own background in Marketing and E-Commerce.

He is a natural marketer, able to see and develop the grand strategy but at the same time translate this to the ground level in tactics and actions. He has always been laser focused on results and has a keen interest in data and its role in the marketing process. He is enthusiastic, diligent and certainly entrepreneurial.

I have no hesitation in recommending Mat as someone who can lead and develop a Marketing or Sales team to achieve great results.
