Just like anything else in life. Ask around, pick up the phone, send an email requesting more info, ask for references. And if you are in a position to share time or money, find and organization that provides these services and help them with outreach or mentorship. It's something within reach for a lot of folks already in tech. In minority communities with first generation immigrants they may not know that services like these exist. Try to spread the word within those communities too through local community groups.
