You get to make a huge impact on a kids life - Mannies of L.A by Mannies of L.A published on 2019-05-14T01:26:32Z There’s nothing better than knowing you changed a kid’s life for the better. Being a manny allows you to work one-on-one with a child in the home setting and really become a huge part of his/her life. I have mannies that have had a manny growing up and they remember looking up to them and still, to this day, talk about the impact he had on their life.
