What Others Have to Say

Aaron Mattson
CEO, Mafic Consulting Group
I have worked with Allegra through my Consulting Firm Mafic Consulting Group for some time. Her integrity, professionalism and depth of knowledge on geologic hydrogen has been of significant assistance to our growth and knowledge of the subject. I trust her capabilities and her diverse background working in a commercial and academic environment. It has been helpful in examining the holistic factors that affect exploration and development for geologic hydrogen.
David Hobbs
Chairman, Pantheon Resources PLC
We appointed Allegra as an Independent Non-Executive Director because of her deep knowledge of the Alaskan North Slope Super Basin and a keen understanding of what it takes to transition from exploration to exploitation. As a director, she role models the candor that is needed to raise the relevant questions and is unafraid to consider all the options. She is committed to exceptional corporate governance across all functions of the company.

Gretchen M. Gillis
 2022 AAPG President
Allegra Hosford Scheirer consistently demonstrates competence, adaptability, and vision in her work, from basin and petroleum system modeling (BPSM) to more recent work in exploration for hydrogen. I had the privilege of getting to know Allegra and her colleagues in the BPSM group at Stanford University, where I saw first hand how she achieved stellar results by eliciting great work from all involved. She has a rich scientific and academic background, enhanced by excellent nontechnical skills that make it a pleasure to work with her, so I recommend Allegra with great enthusiasm.
