The MSMWO Difference

McElroy, Sullivan, Miller, Weber & Olmstead, LLP was founded over 35 years ago. We represent clients in a wide range of matters involving oil and gas, natural resources, water, and environmental law.  Our attorneys practice in state and federal trial and appellate courts and before numerous state and federal agencies including the Railroad Commission of Texas, the Texas Commission on Environmental Quality, the Texas General Land Office and the U.S. Environmental Protection Agency.

Our attorneys bring a unique blend of courtroom and agency experience and technical knowledge to assist our clients in all aspects of their energy, environmental and water law matters.  Our attorneys have handled civil trials and appeals helping to shape Texas oil and gas case law. All of our lawyers are driven to achieve the best result in the shortest time possible.  We work hard to find creative, efficient and inexpensive solutions to our clients’ complex legal issues.

The firm has developed one of the largest energy practices in the State of Texas providing our clients with years of knowledge and experience in regulatory proceedings, applications and contested cases.  Several of our lawyers have worked at the agencies where we represent clients.   Five of our lawyers also have engineering degrees which allows the firm to take on technically challenging cases.

Our clients span from multi-national and Fortune 500 companies, to local governmental entities, environmental non-profits and landowners.  Providing legal counsel across a wide spectrum of clientele allows our attorneys to evaluate cases from differing perspectives. We are dedicated to providing our clients with the best representation possible.
