A believer that hard work and determination can lead to amazing results. Greg has used this approach in all aspects of his career.

Greg grew up in Brandon, Mississippi and graduated from Belhaven University with a Bachelor’s Degree in Accounting.  After graduation, Greg worked for a regional moving company as its office manager.  However, Greg found his calling for the law when he made a career change taking a position as a paralegal for a Jackson, Mississippi based tax law firm.  Greg used the skills he learned as a paralegal working closely with clients to further his legal career.  He then went on to finish his legal education at the University of North Dakota School of Law.  During law school, Greg was a member of Law Review and represented his law school at a national appellate moot court competition.  He also clerked for a Maricopa County Superior Court Judge while in law school where he got hands on experience inside the courtroom.

“Amazing work and amazing job! Did everything perfect and the ruling went amazing . I recommend Greg 10/10. Thank you again for the help and constant communication threw out the case.”

Avvo Review

After earning his Juris Doctorate, Greg began his career working in employment law where he assisted people through tumultuous times.  Greg then went on to work in commercial contract law where he found a true love for the courtroom.  In this capacity, Greg had the opportunity to see cases from both sides’ point of view, and found that he wanted to spend his life helping people through their difficult situations.

In his free time, Greg enjoys spending time with his wife and their dogs.  They enjoy traveling and all things food related.  Greg also loves to spend time watching hockey.
