Nick in real life

What keeps you busy outside of work?

Outside of work, I enjoy spending time with my wife, Ruth, and our son, Liam. We like to stay active outdoors, whether hiking or making the most of the beaches here in San Diego.

Why do you like working at Mercer Advisors?

I enjoy working at Mercer Advisors because it’s a highly knowledgeable team where people genuinely support each other, work collaboratively, and stay focused on delivering the best results for the client.

What makes you tick?

I’m driven by solving complex problems and getting the details right. Outside of work, my family keeps me grounded — I especially admire seeing my wife come from Spain and put in the effort to learn English and build a life here.
