Professional Background

Michael began his legal career in Nashville at the law firm of Harwell Howard Hyne Gabbert & Manner, P.C. (aka h3gm), where he served as an associate in its corporate practice group for seven years. When h3gm dissolved in early 2016, Michael found himself in need of a new home, preferably one that would permit him to continue practicing in the efficient, client-centric way he had emphasized while at h3gm. Upon meeting Kevin, Allison, and Saul with Klein Bussell, he knew he had found that new home, and joined the firm as a member in March 2016.

Michael’s law practice encompasses a wide range of corporate subject matter, including assisting clients with structuring corporate transactions and joint ventures, negotiating private equity investments (whether on behalf of investors or founders), negotiating complex commercial contracts, and structuring and negotiating secured transactions. Michael particularly enjoys the opportunity to engage with clients on a long-term basis and learn their business in depth. Michael has found that having such knowledge ultimately leads to greater efficiency and vastly better legal work product, both of which his clients seem to appreciate.

Personal Background

A native Middle Tennessean, Michael was born in Fayetteville and raised in Murfreesboro. After high school, he moved to Nashville to attend college at Vanderbilt University, where he majored in Electrical Engineering and Mathematics, graduating summa cum laude and with honors in Electrical Engineering. Upon graduation, Michael accepted a job at Deloitte Consulting and moved to Atlanta, which ultimately became his base of operations for seven years. While with Deloitte, and later self-employed, Michael worked as a management and technology consultant, assisting clients in over 15 states, as well as Canada and Mexico, with business process reengineering.

While working on a project in London, Ontario (in January) and after having racked up several hundred thousand frequent flier miles and hundreds of hotel nights as a road warrior, Michael decided a career change was in order. After briefly considering business school, which many of his colleagues had opted to do, Michael concluded that training as an attorney offered the best opportunity to leverage his knowledge of business and technology in an entirely new way, and one that would incidentally allow him to move back home to his native Middle Tennessee. After two years of preparation and planning, Michael accepted a full scholarship from Vanderbilt Law School and returned home to Nashville, where he has lived ever since.

Michael’s family is largely based in and around Lincoln County, Tennessee, where he was born. His parents, along with his sister’s family, an aunt and uncle, and cousin all have made their homes on what was in his mother’s youth, a 250+ acre dairy farm operated by Michael’s maternal grandfather. The farm, located near Petersburg, Tennessee, has been in his family since his great, great grandfather first acquired the land. While he lives in downtown Nashville today (with a couple of incorrigible Italian greyhounds), he often finds himself traveling down to Lincoln County on the weekends to see his family. In addition to spending time with family, Michael’s interests include reading, science and technology, cars, travel, and good food.
