Kimberly Benjamin started her career as a lawyer because she loved helping people.  At the time, she did not have a clue that the criminal justice system was not fair to everyone and that innocent people were actually arrested and in prison.  She quickly learned the truth as a public defender in Kansas City, Missouri, where she came to be known as a zealous fighter for her clients in and out of the courtroom.

Kim is known among her peers as an expert DWI and criminal defense lawyer and a spectacular trial lawyer who obtains unbelievable results for her clients.  She has a passion for her work that emanates from her when she is in her element. She even assisted a civil law firm in suing a large corporation on behalf of an employee who was unlawfully discriminated against, helping them obtain the largest verdict in an employment discrimination case in Cass County.  Because she loves helping people who are facing Goliaths like the government and corporations, she will continue to help other law firms in obtaining great verdicts in a jury trial. 

Her desire to help more and more people caused Kim to find some of the best trial lawyers in Kansas City who shared her passion for defending the accused.  She founded the Missouri DWI & Criminal Law Center at the Benjamin Law Firm so she could build a team of lawyers and legal assistants who focus on being the best at criminal and DWI defense.  With that goal in mind Kim decided that her law firm would be the only one in Kansas City where the lawyers are all trained in the Gerry Spence Trial Lawyers College (TLC) methods. Kim attended TLC as a young lawyer in 2000, and joined the faculty at TLC in 2008, where she regularly teaches other lawyers how to win trials.

In addition to teaching, Kim is a sought-after speaker at legal seminars due to her tremendous success in the courtroom.  She is on the faculty at the National College of DUI Defense (NCDD) and is the chair of the Bernard Edelman DWI Law & Science Seminar in Missouri.  Kim regularly teaches lawyers about criminal and DWI law at seminars sponsored by the Missouri Bar, Missouri Association of Criminal Defense Lawyers (MACDL), NCDD, Missouri State Public Defender System, Kansas City Metropolitan Bar Association (KCMBA).  

Kim is a lifetime member of MACDL, is a Fellow of the Bar with the KCMBA, is a board member of the Cass County Bar Association, and continues to actively serve on the board of MACDL, for which she was President in 2013-14.  She was also honored to be appointed by the Missouri Governor to a term on the Missouri Ethics Commission.

Kim has received awards for her exceptional trial work on behalf of clients, including MACDL’s prestigious Atticus Finch Award and the Missouri Lawyers Weekly’s the Women’s Justice Award for litigation.

After obtaining 2 bachelor’s degrees at the University of Missouri at Columbia — where she was active in student activities and her sorority, Kappa Alpha Theta — Kim attended law school at the George Washington University Law School in Washington, DC.   She was honored in law school to be an editor for one of the university’s law journals and to work at the Pentagon, just as her father had done when she was a child. As an Air Force brat, Kim lived in California, Alaska, Virginia and Washington, DC, before her father retired from the USAF.  Her family settled in Harrisonville, MO, where Kim graduated high school as President of the Student Council and leader of several organizations.

As a veteran, Matthew Gass understands the pressure of being under the gun and in a fight.  In criminal defense, the fight for our client is not always a popular position—but every single client is treated with compassion, the understanding that you deserve a defense, and the promise that this firm will fight to protect those who cannot defend themselves against the government.

Matt first learned how to vigorously fight for his clients at the Missouri State Public Defender, and after a few years joined forces with other former public defenders at the Missouri DWI & Criminal Law Center at the Benjamin Law Firm.  Matt continues to advocate for and protect the rights of his clients.  

In 2015, Matt enhanced his trial skills at the Gerry Spence Trial Lawyers College (TLC), which is the best trial lawyers training program in the country.  He recently attended the TLC seminar that focuses solely on criminal defense where he sharpened his skills to better fight for his clients.  

Matt’s experience includes fighting for clients in nearly 2000 cases, including serious felonies.   He has handled over 100 contested hearings and trials with successful results for very satisfied clients.   

For the past 3 years Matt has attended the Missouri Municipal and Associate Circuit Judges Association conferences, and he also regularly attends TLC meetings and Missouri Association of Criminal Defense Lawyers (MACDL) seminars.  

Matt grew up in Marshall, Missouri, and now resides in Jackson County with his wife Bethanie, twins Josh & Ryan, and a little one on the way.  He studied Political Science at Clemson University and the University of Missouri–Columbia where he graduated in 2004.  While attending undergrad, he participated in Air Force ROTC, earning an Officer Commission in the United States Air Force and was stationed at Whiteman AFB, Missouri from 2004-2009 where he worked as an Executive Officer, and achieved the rank of Captain before leaving for law school.  In 2006, he deployed with the 393d Bomb Squadron, one of only two B-2 Stealth Bomber units in the world, to Andersen AFB, Guam as part of the Bomber Forward Presence/Global Strike mission.  He received his Juris Doctor law degree from the University of Missouri-Kansas City in 2012, and has been licensed in Missouri since 2013.

Confident, knowledgeable, and experienced, Craig has represented thousands of citizens charged with serious felonies throughout Missouri. Whether it be in small towns, or big cities, each and every one of Craig’s clients know that he is ready to stand up to Judges, Prosecutors, or anyone on their behalf.  He has achieved acquittals for clients charged with violent acts, sex crimes, and other serious matters. He is a respected trial attorney with over 30 felony jury trials under his belt and is ready to go to court, again, to fight for you.

Craig started his professional career as an investigative reporter after graduating from Wright State University with a degree in Communications Studies.  In the mid-90s he worked at one of the last small-town daily newspapers — the Pulitzer Prize-winning Xenia Daily Gazette. He spent many days in court, covering trials of various crimes of note to the community and became a Court Appointed Special Advocate for the Juvenile Court. 

This rekindled his long-held desire to go to law school and become a lawyer. He returned to his hometown and completed the UMKC School of Law in 2003. Since that time, Craig has continued to pursue his love of trial work and being a thorn in the side of a justice system which has forgotten all citizens are innocent until proven guilty.

Craig has spent his professional life since admission to the Missouri Bar in 2004 in pursuit of top-notch experience and training. He has taken most of the advanced trial training available to Missouri attorneys. He spent many years teaching trial skills to public defenders from all over the state, and in 2015 graduated from the National Criminal Defense College’s Trial Practice Institute. NCDC is an intensive two-week exploration of the criminal trial and breaks down each phase to increase advocacy and success. Craig also attends the local Gerry Spence Trial Lawyers College (TLC) meetings with his colleagues at the law firm and enjoys combining his trial experience with the advanced TLC principles.

Since focusing on DWI/DUI work he has attended the DWI/DUI Bootcamp with two of Missouri’s DWI/DUI Defense Veterans, and attended DWI/DUI investigation training with a former law enforcement officer and international law enforcement instructor. 

Born in Kansas City, Missouri, Craig has called Kansas City home for most of his life. He currently resides in Waldo with his wife, Jen, kids Aidan and Ayla, and rescue dog Blizzard.

Case Manager
