About Me

I am committed to fighting for your rights and working diligently to achieve the best outcome possible in your legal matter. I am honored to practice law in the State of Louisiana, and the Parishes of Ascension and East Baton Rouge and the surrounding areas. I will care for your legal matter as though it were my own. I understand that you worked hard to earn the fees paid to my office - I will give you a diligent and honorable effort in return.


Personal Bio:


Born and raised in Louisiana, I spent significant time in Tennessee and Georgia in the 90s, but returned home to go to school and I have lived here since 1998.  


I spent more than twenty years in the restaurant business, culminating in managing a premiere white table cloth steak house, where I was responsible for the 3000 bottle wine list as the sommelier.  I also ran the day-to-day operation of the restaurant, a skill set I hope to put to use in the restaurant business, in some capacity, after establishing my law practice.


I have an undergraduate degree from Thomas Edison State College in New Jersey. I finished there while deployed to Kuwait/Iraq in 2004 with a degree in Philosophy. I had studied at Louisiana State University for 3 1/2 years prior to finishing at the on-line college.   


I graduated from the Paul M. Hebert Law Center at Louisiana State University in the spring of 2008, where I was a two time finalist in the Ira S. Flory Moot Court competition, and a member of the 2007-2008 Moot Court Board.


After spending a little time working at a small firm in the Ascension Parish area, I opened my own firm in June of 2010. We now have two attorneys and two offices, one in Baton Rouge and one in Gonzales. Our practice is primarily focused on Felony Criminal Defense and DWI defense. However, we do handle many personal injury and family law cases, especially if you think the matter may go to trial.


I am also a contract attorney with the 23rd JDC Indigent Defense Board, as a public defender in Div. A. 


Military Bio:


I joined the U.S. Military in October of 2001, both in response to the terrorist attacks of Sept. 11, 2001; and a desire to join ROTC at LSU. I transferred to the 22nd LSO Trial Defense Service, criminal defense arm of the JAG Corps, in December of 2003, to function as a 27D, paralegal, in an environment that would offer the opportunity to learn about the practice of law.


In May of 2004, I volunteered to be deployed to Iraq. I was sent to Kuwait where I was the NCOIC of the Kuwait Trial Defense Service office. The attorney for whom I worked was assigned to one of the Abu Ghirab soldiers, and we functioned as her defense team for the duration of my deployment. We spent significant time traveling to Iraq in support of soldiers as legal defense. In addition, we had 5 General Courts Martial, and about 400 Article 15 proceedings, non-judicial punishment in the UCMJ. I redeployed in Jan of 2005, and returned home shortly thereafter.


Since my return, I have been a member of the Trial Defense Service, Team 15, in New Orleans, LA. My military career will come to an end in Oct. of 2013.
