Experience You Can Count On

Steve knows both sides of the attorney/client equation as he worked in a corporate capacity retaining attorneys prior to becoming an attorney and then, after entering private practice, retaining and managing other attorneys joining as team members to address client needs. From this firsthand experience, he knows what you as a client expect from an attorney—and perhaps more importantly, what you do not expect. Business clients want an attorney that is experienced, knowledgeable, and possesses character. Clients seek an attorney that shares the same values and is willing to work collaboratively to achieve agreed-upon goals. Steve teams with his clients to seize business opportunities, solve problems, and collaborate with experts and other attorneys as appropriate.

Before shifting careers in 2004 to devote himself exclusively to the private practice of law, Steve had a substantive 24-year career with the transportation giant, CSX Corporation, holding senior-level positions in finance, executive, law and government affairs. While Assistant Vice President of Cost & Economic Analysis, Steve had responsibility for screening proposed capital expenditures prior to submission to the Board of Directors for approval. Steve served in the company’s executive department as chief of staff to the President before assuming the position of Regional Vice President for State Relations (District of Columbia, Delaware, Maryland, and Pennsylvania), where he represented the company’s interests before state and local governments. During his CSX career, Steve was prominently involved in the merging of the Chessie and Seaboard railroads to form CSX, and the acquisition of Conrail. Steve negotiated many prominent agreements with the State of Maryland for MARC commuter rail service, Seagirt port facilities, and the sale of property for the Cumberland C&O Canal Place.

Concurrently with his business career, Steve was an adjunct faculty member at the Johns Hopkins University School for 10 years in its Master of Business Administration program. For several of these years, he headed the economics department while teaching graduate economics and finance courses.


Steve’s unique ability to work with diverse interests was recognized by Governor Schaefer when he appointed Steve to the Maryland Greenways Commission to form a system of interconnecting recreation trails and wildlife corridors to link protective buffers along Maryland’s waterways. Governor Schaefer again appointed Steve to his Flood Mitigation Task Force for Western Maryland to study flooding and develop long-term solutions to prevent or minimize local disasters. Steve was appointed by Pennsylvania Governor Tom Ridge and reappointed by Governor Mark Schweiker to the Pennsylvania Rail Freight Advisory Committee to provide guidance on developing state transportation policy and funding.

Steve served as a board member of the Maryland Chamber of Commerce and the Children’s Cancer Foundation, and as Treasurer of St. Peter’s Episcopal Church. Steve is a graduate and member of Leadership Maryland, an independent statewide leadership program to develop informed senior-level leaders, and a member of Vistage, a global community of business professionals committed to growing, learning and becoming better leaders.

Stephen Thienel is very knowledgeable of legal matters pertaining to business. I have used him for several years now and he is always thorough and prompt in his responses. Whether providing business advice as I grow my business or working up my personal and business tax returns, you can always count on comprehensive advice and professional support. Starting a business can be a little stressful as you can only get so much from college and through performing research. Nothing beats real life experience and Steve’s support to my business has meant a great deal to me, and has served to reduce my stress and frustration considerably. I have enough issues to work through in my business. Having Steve to cover my back on legal and tax matters makes it seem like he is really part of my senior staff. I would highly recommend his firm to anyone, especially young start-up businesses like mine.
