Mark Brengelman became interested in the law when he graduated with both Bachelor’s and Master’s degrees in Philosophy from Emory University in Atlanta. He then earned a Juris Doctorate from the University of Kentucky College of Law. In 1995, Mark became an Assistant Attorney General and focused in the area of administrative and professional law. He represented multiple boards as General Counsel and Prosecuting Attorney.

Mark retired from state government in the summer of 2012. Also in 2012, he became certified as a hearing officer. He then opened his own law practice to focus on government services and consulting, continuing education, and the representation of health care practitioners before licensure boards and in other professional regulatory matters.

Expanding his health law experience, he was a registered legislative agent (lobbyist) for the Kentucky Association of Pastoral Counselors for the successful passage of Senate Bill 61 passed by the Kentucky General Assembly and signed by the Governor into law on April 9, 2014.

Mark is a frequent participant in continuing education and has been a presenter for over a dozen national and state organizations including the Kentucky Bar Association, the Kentucky Office of the Attorney General, and the National Attorneys General Training and Research Institute.

He is the founding presenter for "Navigating Ethics and Law for Mental Health Professionals," a continuing education training approved by five Kentucky mental health licensure boards, which was presented at Midway College with a licensed clinical social worker in 2013 and 2014.

Since October 2013, Mark has practiced law with the firm of Hazelrigg & Cox, LLP, as partner - an established law firm tracing its history in Frankfort, Kentucky, over one hundred years.
