“My name is Stewart McCarthy and I work as a Principal Experience Designer at Slalom Build. As I have progressed in my career, I have began to see that one thing that often prevents people from growing in their role is the perception that people in higher positions got there by being masters of their craft. I love to be able to give confidence to others and prove that determination, attitude and soft skills are often work more than technical ability.

What Mentees say


Marie Doyle, UX Designer

“Being mentored by Stewy felt very collaborative. He was a great sounding board for ideas, providing creative direction while also advising on the practical aspects of designing for screen.”

Stewy's certificates

These certificates represent the number of mentees Stewy has successfully guided to completion of the UX Tree Mentorship Programme. It’s worth noting that a mentor might have fewer certificates than the total number of mentees they’ve begun mentoring, as not all mentees complete the program.
