Tom Sengewalt focuses his practice in energy and natural resources law, representing clients in both litigation and transactional matters. Tom’s experience includes two posts in-house with a publicly-traded Appalachian natural gas E&P company first, working as in-house counsel, and the second, leading major transactions involving the company’s oil and gas assets. During his time in-house, Tom grew his arsenal of energy industry knowledge, as well as his project management skills and understanding of business operations.  While in-house, Tom witnessed the good, bad, and ugly of client service and has a greater appreciation for the level of responsiveness, efficiency, and attention to detail that clients expect and deserve.      

Tom’s prior experience with the firm includes representing clients in energy, commercial, and toxic tort litigation in both state and federal courts and providing counsel and support to clients during all stages of energy transactions of all shapes and sizes. Tom’s unique blend of experience allows him to understand and appreciate the business needs of his clients, leading to efficient and effective results.  

As a lawyer and as a colleague, Tom is the perfect combination of service oriented and business minded.
