So initiative in your position and how you became a mentor or how they can be one .The benefits of being a mentor

find and seek out the mentors

Some accompanied have formal programs with assigned mentors. Other than that ask around- who's an experienced employee with valuable expertise? Often people are pleased to share their knowledge.

If so, arrange a good time and have a few questions ready to get things going. You should be able to build up a professional relationship that way over time.
