Sharon Tanghal, L.C.S.W.

I made the decision to be a follower of Jesus and was baptized when I was 9 years old. When I was 19 y/o, I studied the book of Romans and truly experienced what grace and having the assurance of my salvation was all about! I graduated from my Masters in Social Work from California State University, Long Beach in 2005. I became a Licensed Clinical Social Worker in 2010. Several years ago, God stirred in me a strong desire to serve families in my surrounding community and in 2019, NEW PAtH - a faith based parenting program was born. I'm happily married to my husband, Oliver, of 17 years and we have two beautiful and amusing daughters, Leia (11) and Ariel (6).
