Associate/Attorney at Law

Thomas Tompsett Jr. is a seasoned trial attorney and registered lobbyist who joined HJM in the spring of 2017.  Tompsett’s reputation for honesty coupled with a fiery, competitive spirit has made him a successful and respected attorney and advocate.  Since joining HJM, Tompsett has been deeply engaged in a spectrum of public policy matters, which include, but are not limited to, mental health issues, domestic violence, construction law, business regulation, land use, real property, and public education.  As a lobbyist, Tompsett strives not only to shape sensible policy for his clients but to assist them in raising their profiles both in Annapolis and throughout the State of Maryland.

Before joining HJM, Tompsett was the lobbyist for the Maryland Multi-Housing Association (MMHA), a trade association that represents the owners and managers of more than 183,000 residential rentals units throughout the State of Maryland.  At both the state and local levels through powerful oral and written testimony, one-on-one engagement with elected officials, and candid discussions with print and TV journalists, Tompsett zealously worked to preserve the property rights of MMHA’s members while also thwarting legislative proposals that would have negatively impacted their business and financial interest.

Tompsett learned the art of persuasion and negotiation as an Assistant State’s Attorney with the Baltimore County State’s Attorney’s Office.  Tompsett spent his eight and half years as a prosecutor passionately representing the citizens of Baltimore County and the victims of violent crime.  Never afraid to try a case before a judge or a jury, Tompsett was regarded as a principled, but reasonable, prosecutor.

In the in the fall of 2017, Tompsett served as co-counsel to HJM Member Sean Malone and made national news after they successfully represented a Baltimore City Police Officer before an administrative trial board on charges that stemmed from the 2015 arrest of Freddie Gray.  Despite the high-profile nature of the case, the intense media scrutiny, and the fact that the hearing was held in a law school auditorium to accommodate the public who wanted to attend, the trial team of Malone and Tompsett was able to navigate and negate all the administrative charges lodged against the officer, who remains a valuable and respected member of the Baltimore City Police Department.

Analytical, yet conversational, Tompsett can convey complex legal theories in straightforward, relatable terms.  For all these reasons, Tompsett is a crucial complement to HJM’s team of skilled and highly respected advocates.

In addition to his lobbying efforts, Mr. Tompsett maintains a boutique criminal defense and administrative law practice with a manageable case load to give your legal matter the attention it deserves.  In regards to criminal matters, Tompsett defends misdemeanor and felony charges including driving under the influence (DUI), driving while impaired (DWI), theft, assault, white-collar crime, and homicide in every county in the State of Maryland.
