Jon Donnel joined B. Riley Financial’s subsidiary Great American Group Advisory and Valuation Services, as managing director of Oilfield Services based in Houston, TX.

Donnel is an experienced advisor specializing in business valuation, investment appraisal and financial planning for companies and lenders across the oilfield services industry.

“Jon brings significant oil and gas industry experience to our firm and is a welcome addition to our growing energy services team,” said Mike Marchlik, CEO of Great American Group. “Our firm has built a stellar reputation in serving all business segments of the energy sector for over 40 years, from oilfield services to upstream to midstream to downstream. We look forward to Jon’s contributions as we continue to broaden the complementary services we provide to our clients across the commodity and energy value chain.”

Specializing in energy finance for more than 15 years, with an emphasis in the oilfield services sector, Donnel’s expertise spans asset and equity valuation, investor relations, financial modeling and litigation support. He previously served as director of investor relations at Weatherford International, a large multinational oilfield services company, and as lead utilities and oilfield services equity research director at Scotia Howard Weil, an energy-sector focused investment bank.

Earlier in his career, he served as a financial analyst with ConocoPhillips, an integrated global oil and gas company, and as a consultant with Houston-based accounting firm Compton & Wendler.

“The complexity of today’s capital markets environment requires technical financial skills and industry knowledge to not only assess, but also to preserve and maximize the value of assets across the energy complex,” said Donnel. “Our team draws on a rare combination of industry, banking, consulting and government experience to support our clients’ evolving needs and I look forward to contributing to our oilfield services clients’ future success.”
