History and Philosophy

MAD Scientist Associates, LLC (MAD) was established in 1998 by husband and wife team, Christine S. Dilley and Mark A. Dilley.

MAD provides high quality wetland and ecological consulting services to clients in the public and private sectors. Our clients include engineering firms, universities, park districts, industries, and municipal governments. Clients have come to rely on MAD for threatened and endangered species/critical habitat surveys, full wetland services (delineation, permitting, mitigation & monitoring), stream characterizations and aquatic studies, botanical surveys, ecological risk assessments, and other specialized ecological services.

Our Core Values

MAD Scientist Associates is built on the following core values:

An Appetite for Excellence – Strive for the highest quality in our work product, our work environment (including safety), and our individual and collective/company reputation.

Commitment to the Greater Good (Environment AND People!)  – This is our “North Star” of core values.  Put the team ahead of self, and help foster a collaborative work environment to optimize our functionality and productivity.  Be loyal and committed to our company, our clients and our community and help whenever possible. Hold the belief that any project can be done better (e.g., with less damage/greater improvement to the environment), regardless of the project type or client industry sector.  Efforts to educate others on environmental issues, particularly those related to wetlands, water quality, and biodiversity, are one of the key means by which we honor this commitment.

Communicativeness – Communicate frequently, in a manner that is transparent, honest, respectful, and effective. Share your knowledge freely to build your reputation and enrich the knowledge of others (this aligns with our North Star core value above).

Desire to Keep Work Fun!  – Have a sense of humor; be approachable, friendly, and able to exhibit grace under pressure, both in the office and in the field.

Entrepreneurial Spirit – Use outside-the-box, creative thinking and problem-solving to help continue to build the company’s reputation for innovation.  Be adaptable and flexible to help us manage workloads, adjust to shifting priorities, and achieve our shared goals.

Humility – Be open-minded and embrace different views; express differences of opinion politely.  Know “your stuff,” but be humbly confident.

Self-motivated and Professional – Anticipate needs and contribute to the team’s and company’s success; seek out and take advantage of opportunities for personal and professional development.  In all endeavors, be honest and consistent; honor your commitments and keep your word. Integrity and professional conduct builds a reputation.

We believe these core values can be summed up in “Three Rs” for Our Company:  
Relationships – Responsibility – Reputation
