Meet Who's Behind TRE

Dena Wojtach

President at TRE, has more than 30 years of experience in the air quality field,  working at state and county levels of government, as an environmental consultant, and as a small business owner:

  • Conducting compliance audits
  • Preparing permit applications
  • Interpreting and applying local, state, and federal air quality regulations, policies, and guidance
  • Engaging scientific, engineering and legal experts
  • Soliciting public input
  • Crafting both regulatory and voluntary air quality improvement projects and programs
  • Developing new regulations and policies based on sound science
  • Advising legislators and decision-making boards and commissions
  • Petitioning for rulemaking and advocating for positions before decision-making boards, commissions, and agencies

This extensive air quality experience is complemented by a varied and well-established network of peers and other experts.

TRE is named for Robert Frost’s “The Road Not Taken” poem. As a result of 30 years of air quality experience, Dena has observed that air quality managers and organizations must now seek non-traditional air quality improvement opportunities to develop localized air quality improvement projects and programs that go beyond reliance upon federal regulations. Taking the road less traveled can make all the difference.
