We are Gryphon Scientific

Gryphon Scientific is a small business with a unique focus on projects that require expertise in the physical and life sciences as well as public health. The energy of our small business environment, as well as our commitment to technical excellence, attracts staff with the highest qualifications and clients who consistently report high levels of satisfaction with our work.

The backgrounds of our staff enable us to tackle projects with complex technical challenges. Staff bring experience in the laboratory and in policy shops as well as hands-on experience in the field. In addition to a level of innovative thinking and creativity that typically exceeds client expectations, we recognize the importance of effective communication and have been complimented on the clarity of our science writing and data visualization.


In leaving one of the nation’s largest public policy research firms, Rocco Casagrande, Joan Mullen, and Kimberly Legrow founded Gryphon with the aim of creating an organization where scientific rigor and analytic excellence would thrive with no pressure to grow revenues at the expense of technical achievement.
