We support the Global Soap Project! learn more

For 30 years we have engaged in sustainable practices that conserve natural resources and reduce our impact on the environment that include:

  • being paperless wherever possible; optimizing printed matter for low ink usage; recycling ink/toner cartridges
  • complying with state and local environmental laws
  • decreasing energy use (we are down 22% from last year)
  • deploying reuse programs
  • encouraging employees to telecommute
  • focus on green dining
  • ENERGY STAR® appliances
  • make and use our own organic soap
  • not supplying hair dryers
  • using toilet paper made from paper (not from trees), unbleached and septic-safe
  • unplugging "energy vampires" when not in use (learn more)

We hope you will join us in our quest to preserve and protect the environment.

“We had a FANTASTIC time. The museum just gives and gives with each new step you take. As one of our group said: “I felt like I have seen nothing and EVERYTHING!!!!” And to be able just to relax and enjoy–it is such a great museum experience. Can’t wait to come back to see all the new things and to find more and more secrets that are hidden in your corners!!!!”
