Can I Beat My DUI Case?


In 2000, Mr. McKenzie obtained his Bachelor of Arts degree from Franklin & Marshall College in Lancaster, Pennsylvania. While attending F&M Mr. McKenzie focused his elective curriculum on pre-law courses to satisfy his then-budding interest in the legal profession. As a balance to his studies, Mr. McKenzie was also a four year member of the football team, the mighty Diplomats, and was awarded the Offensive MVP honor by his teammates at the conclusion of his senior year.

Mr. McKenzie reached another professional milestone in 2003 when he obtained his Juris Doctorate degree from Penn State University Dickinson School of Law. In addition to his studies, Mr. McKenzie also made time to intern at the Dauphin County District Attorney’s Office where he was bestowed many of the obligations and duties classically allotted to the attorneys of the office. It was there that Mr. McKenzie, still a law student, was privileged to try multiple jury trials.Upon graduation Mr. McKenzie was offered a position with the Dauphin County District Attorney’s Office as an Assistant District Attorney. During his tenure as an ADA Mr. McKenzie prosecuted numerous adult and juvenile cases, from inception through appeal, whereby he expounded on his innate skills of preparation, presentation, and negotiation. By the time of his departure from the office, Mr. McKenzie had established himself as a firm but fair prosecutor amongst the peers with whom he did battle and the Courts before whom he did advocate.

The beginning of 2007 saw many changes for Mr. McKenzie. In addition to moving to the suburbs of Philadelphia, marrying his college sweetheart Chrissy, and purchasing a home, Mr. McKenzie ventured into private practice, joining the firm of Cipriani & Werner, P.C. While at C&W, Mr. McKenzie focused his practice on general casualty litigation as well as workers’ compensation defense litigation. It was at C&W that Mr. McKenzie first discovered and explored his aptitude for written composition. While it broadened his horizons, it did not sustain him. Mr. McKenzie soon found that he missed the brisk pace of the criminal law he once readily practiced. Mr. McKenzie parted ways with Cipriani & Werner, P.C. in the Fall of 2008 thankful for both the experience and colleagues he had gained.

In late 2008 Mr. McKenzie joined the Commonwealth of Pennsylvania, Department of Agriculture in the role of Assistant Counsel. In his new role Mr.McKenzie had the unique opportunity to return to the aspects of both the criminal and civil law in which he thrived while gaining proficiency in the particulars of administrative law. Though charged with representing the Department in all of its agencies’ litigation matters, Mr. McKenzie’s primary role was as Pennsylvania’s Dog Law prosecutor.

Through the initiative of Governor Rendell, October 2008 yielded the passing of a revitalized and revolutionary new law Dog Law aimed at Pennsylvania’s pervasive puppy mill problem. Mr. McKenzie and his esteemed colleagues were first to tackle the nuances of this law and, through their tireless efforts, brought about a welcomed change in Pennsylvania.

Mr. McKenzie founded McKenzie Law Firm, P.C. in 2010 in an effort to further broaden those horizons he had diligently worked to expand throughout his professional career. It is Mr. McKenzie’s unwavering goal that he utilize the education and unique experiences from which he has benefited to the success and satisfaction of all his clients’ legal needs, focusing on DUI & Criminal Defense. In November of 2011, Mr. McKenzie threw his hat into the ring of politics, running for a contested position as Commissioner within his local township. Mr. McKenzie was successful in his endeavor and, as a result, sits on the Board of Commissioners for West Norriton Township.

Then in November 2014, Mr. McKenzie ran for a seat in the Pennsylvania House of Representatives, 150th District, against an 8 term incumbent and county chair of the opposing party.  Though he lost the election, Mr. McKenzie gained many new friends and allies through his seemingly endless voter canvassing and political fundraising.  He brings the same dedication and passion to the needs of West Norriton and District 150 residents as he does the clients of the McKenzie Law Firm, P.C.
