Paula Del Giudice is PPRC’s Executive Director. Formerly the director of the National Wildlife Federation’s Western Office in Seattle, she brings many years of nonprofit management experience to her position. In addition, she has worked as a tireless advocate on aquatic ecosystems in the Northwest—especially salmon habitat; federal issues such as the Endangered Species Act, Clean Air & Clean Water acts; climate change; and public land management and wildlife issues in Nevada. Prior to working as an environmental nonprofit manager, Del Giudice wrote about environmental issues and outdoor recreation for several daily newspapers and many regional and national magazines. In 2008, she was awarded the top environmental award by the Outdoor Writers Association of America—a group of which she’s been a member for 31 years. She has a B.S. in Business Administration from the University of Nevada, Reno, and a M.Ed. from Regis University.When she’s not trying to stay in touch with her kids who are both in college at the opposite ends of the country, she loves to read, cook, fly fish, backpack, do hot yoga, and paint with watercolors. She is also an accomplished glass artist who began participating in shows last fall. This year she went back to running and finished in the top 10 in her age group in three 5Ks.

Michelle Gaither, Industrial Engineer

Michelle Gaither has workeMichelle Gaitherd in the field of environmental technical assistance for fifteen years, helping industry, government, and institutions reduce waste, pollution, toxics, and resource consumption.

Michelle has an M.S. in Environmental Science and a B.S. in industrial engineering, and career experience in both areas. The two disciplines complement each other in addressing environmental issues and solutions. Currently, at PPRC, projects include Integrating lean manufacturing and environmental methods for synergistic results, systematically evaluating safer chemical alternatives, and general research, writing, and sleuthing solutions for PPRC’s rapid response  inquiries around toxics and waste reduction.

Prior to PPRC, Michelle’s work experience included: management of research projects for the Clean Washington Center to develop applications for using recycled materials; Support of the labwide “Environmental Sustainability Project” for Battelle / Pacific Northwest National Labs at the Hanford site; and, manufacturing engineering at a successful electronics company.

Beyond PPRC, Michelle enjoys raising four children, playing and coaching sports, and volunteering with local school and environmental organizations.

Ken Grimm, Industry Outreach Manager

Ken GrimmKen joined PPRC after working extensively in the manufacturing sector. He draws on this expertise while working with various industry sectors, and the challenges they face while simultaneously becoming more competitive and “green.” Contact Ken for information on:

  • Technical and Regulatory Analysis
  • Business Drivers and Incentives
  • P2 Barriers and Opportunities in Manufacturing
  • P2 Results Measurement
  • Technology Diffusion
  • Environmental Management Systems

After leaving college, where his major emphasis was psychology (P2 is all about behavior change, right?!), Ken spent some time in the autobody trade before embarking on a seventeen-year journey in the metal fabrication industry. After stints as a lead painter and supervisor, Ken spent the last six years acquiring a hat collection which included ETC (Employee Transportation Coordinator), ISO 9000 Internal Auditor, Safety Director, Human Resources Manager, and Environmental Coordinator. He received an award of recognition from the mayor for his work as an ETC and has many years of no violation inspections from the Puget Sound Clean Air Agency to his credit, including one which called the facility a model company in the four-county area they regulate.

Outside of work Ken enjoys a variety of activities with friends and family, including fishing, camping, hiking, backpacking, cooking and motorcycle riding. He builds computers as a hobby and currently has 50+ systems in the homes of friends, relatives and neighbors.

Brian Penttila, Chemical Engineer

Brian PenttilaBrian’s primary focus is reducing risk from chemical exposure through source reduction. His interests include assessing risk of consumer and worker exposures and partnering with businesses to identify alternatives for hazardous or suspect chemicals.

Brian is also supporting PPRC’s efforts to increase awareness of the links between pollution prevention and climate change, and addressing technical challenges of calculating emissions. Along with staff environmental engineer Michelle Gaither, he responds to Rapid Research requests from technical assistance providers in Region 10.

Contact Brian for inquiries regarding:

  • alternative chemical assessment or solvent replacement
  • source reduction and industrial/commercial pollution prevention resources
  • green chemistry principles and life-cycle assessment
  • estimating GHG emissions for non-standard processes
  • resources for industrial energy efficiency

Brian has a PhD and MS in Chemical Engineering from the University of Rochester and a BS in Chemical Engineering and Bioengineering from the University of Pennsylvania. He has extensive industrial experience in new product and process development, experimental design, manufacturing technical support, and test method development from physical testing through analytical chemistry.

Sadly to say, his greatest joy is technical problem solving, so, when not actually solving problems, he is probably talking about them while entertaining dinner guests, traveling to distant lands, or pursuing other interests and volunteer activities.
