Joseph Lassen started practicing law in 2003 in New York and New Jersey. He was later admitted to the Texas Bar in 2014. During this time, Joe has primarily focused on divorce, child custody, child support, and numerous other family law matters. He has helped countless families navigate difficult circumstances with compassion and understanding, while still aggressively advocating for his clients in court. He is experienced in all areas of practice including trial, mediation, and settlement negotiation. Before opening his own firm, Joe worked for one of the top personal injury attorneys in San Antonio and Corpus Christi, and also in a high-volume family law practice in San Antonio.
