About
“We won’t have a society if we destroy the environment.” – Margaret Mead
My passion lies in protecting the places we live and breathe in—by creating energy-efficient, low-carbon buildings and ensuring clean, healthy indoor environments for all. I believe every structure, whether a home or a high-rise
I'm the Director of Aspen Environmental and Aspen Air Duct Cleaning, where I’ve been helping people improve their indoor environments since 2012. I graduated from Roanoke College in 2009 and have built my career around creating healthier, more energy-efficient homes and buildings.
Over the years, I’ve earned credentials in BPI energy auditing, Water Restoration (WRT), Certified Microbial Remediation (CMR), Certified Microbial Consulting (CMC), and I'm a certified HERS Rater through RESNET. These certifications help me lead with confidence and bring real solutions to challenges like indoor air quality, moisture issues, and energy loss.
I'm deeply passionate about sustainability, decarbonization, and helping families and businesses breathe easier. When I’m not working, you’ll usually find me outside—fishing, hiking, or spending time in the woods with my family. The outdoors inspires everything I do.

Testimonials
Harvard University
"I would absolutely call this a project saver. Our only other option was to tear down walls and
demolish the building structure in order to access the leaky ductwork. We were very pleased with
the results and I honestly don’t know how we would have solved this issue if the aeroseal
technology wasn’t available.”
John Hollister,
Senior Capital Project Manager
Harvard University
“Any prior concerns we had over the disruption that the aeroseal process might cause in a 24/7
environment were quickly proven to be unfounded. It was probably the quickest evidence of
success I’ve ever seen. We’ve already spec’d Aeroseal into several additional projects.”

"I’m a 100% believer in Aeroseal. I wish we
had it specified for the job in the beginning".

(CAMBRIDGE HOUSING AUTHORITY CASE STUDY)
Initially, there was a lot of skepticism among the building engineers that Aeroseal would
do the trick – especially when they learned that the sealant doesn’t coat the entire inside
of the ductwork but instead, accumulates around the individual leaks. After seeing the
results, they are all now believers and big fans of the technology.
