Josh grew up in Pasadena, Texas, in a blue collar, modest community where many people worked in the refineries just down the road.  Growing up around regular folks who worked in oil & gas and construction gave Josh an understanding of what it meant to work hard and do an honest day’s work.  These principles are what guide his practice to this day.

Josh is a trial lawyer who started his legal career in 2002, and he has litigated commercial and personal injury cases ranging from contract and business disputes to catastrophic injuries, construction defect and delays.  His current focus is on healthcare advocacy for hospitals and freestanding emergency centers, commercial litigation, and first party insurance claims.

Prior to starting his legal career, Josh attended Southwestern University in Georgetown, TX, graduating summa cum laude, obtaining a degree in International Economics with a focus on Asia and Mandarin Chinese studies, along with obtaining a minor in Music and Vocal Performance. Josh then attended the University of Texas School of Law and was awarded the Presidential Scholarship. Following graduating from the University of Texas, Josh began practicing litigation at Chamberlain, Hrdlicka, White, Williams, & Aughtry, PLLC. In 2022, Josh established Callender Bowlin, PLLC with Mark Callender, a founding member of Serpe, Jones, Andrews, Callender, & Bell.

Clients come to Josh when they need a lawyer with grit, and who is a true trial lawyer.  Josh’s litigation skills have landed numerous courtroom and arbitration victories, including disputes between oil & gas and construction companies, partnership and shareholder disputes, trade secret misappropriation cases, and “bet-the-company” cases.  Josh has been named a Texas Super Lawyer since 2020, and a Texas Rising Star from 2012-2017, as well as Top Lawyer in Houston in H Texas Magazine from 2013-2017.
