His father is a retired Hughes County Associate District Judge and was on the bench for 25 years, and his mother taught music for 26 years in Holdenville Public Schools. He comes from a long line of lawyers, many of whom practice in Tulsa or the surrounding areas today.

Leonard Wood, MO and was trained initially as a truck driver. He is a graduate of the State of Oklahoma’s Officer Candidate School Class 44 and was commissioned as a 2nd Lieutenant in August of 1999.

Zach tried a large number of jury trials for the DA’s Office in that time, at one time trying as many as 25 jury trials in a 24-month period.

Upon leaving the Tulsa County DA’s Office in 2006, Zach started his own law firm, practicing for one year before Anthony Gorospe joined him to form the Gorospe & Smith Law Firm in 2007. The vast majority of Zach’s work is in the area of DUI and DUI Manslaughter Defense, but his law firm handles Personal Injury, Criminal Defense, Probate/Wills/Estate Planning, and Family Law.

Having practiced law since 2002, Zach Smith is a Tulsa trial lawyer, and he has handled over 50 Felony jury trials in the past 12 years. Sixteen (16) of those jury trials have been in the past 10 years as a defense lawyer, and eight (8) of those trials resulted in “Not Guilty” verdicts by juries. Among those “Not Guilty” verdicts are several DUI cases, as well as Manslaughter and Murder charges etc.

In 2011 he became the Chairman of the Continuing Legal Education (CLE) Committee, and from 2011-2013, he was responsible for creating, establishing, and coordinating the CLE schedule for the TCBA. The CLE Committee serves an important function, as it is responsible for providing CLE credits to a large number of TCBA members each year, helping ensure TCBA attorneys maintain annual compliance with the requisite number of CLE hours established by the Oklahoma Bar Association. Additionally, Zach has taught the TCBA’s DUI CLE courses to other lawyers in the legal profession for several years now, as well as other various CLE topics on which Zach is knowledgeable.
