Oil and gas attorney Hennessey joins Hiscock & Barclay

Hiscock & Barclay

Attorney Yvonne E. Hennessey has joined Hiscock & Barclay’s Albany office as a partner in the firm’s energy and environmental practice areas. She brings years of experience representing clients in the oil and gas sector on complex regulatory and litigation matters and, more specifically, shale development matters. Hennessey also has extensive experience in the Clean Air Act, hazardous waste site cleanup, and the siting and permitting of energy, solid waste and industrial facilities.

“She possesses as much, if not more, hands-on legal experience in the development of shale projects in New York State as any other attorney, and will be an asset to our extensive base of energy clients as they continue to invest in the development of the Marcellus and Utica Shales,” said John P. Lagan, a managing partner at the firm.

Hennessey started her law firm career with Hiscock & Barclay in 1999 as an associate.  Prior to rejoining Hiscock & Barclay, Hennessey was a partner in The West Firm, where she was Chair of the Regulation and Litigation Practice. Before that she was at O’Connell & Aronowitz and with the Albany office of LaBoeuf, Lamb, Greene & MacRae.  Hennessey is admitted to practice in New York, Pennsylvania and Massachusetts.
