Aaron Carson - Principal

Architect, LEED AP BD+C

Aaron Carson - PartnerAaron has over a dozen years of experience in the architecture industry, primarily working on large scale commercial projects as the Project Manager or Project Architect. While the scale of commercial architecture is an exciting challenge, his real passion is for renewable energy and sustainable architecture. That pursuit led him to co-found SunSource Inc.

As a student Aaron was fascinated by studies of passive solar design, environmental design and the various building geometries that harness available energy strictly through design, with the macro and micro climates in mind. These principles became the focus of his interest through both his undergraduate degree in Interior Architecture and his Master of Architecture degree.

Now after years of practicing the craft of Architecture in the traditional project delivery method, Aaron is pleased to be able to apply that experience to a new way of construction; one which is driven by energy efficiency and performance but also environmentally conscious practices and good design.

Michelle Dunagan

She has over 10 years of experience working in an office setting, supporting customers and tenants with their project and living needs.  She believes that honesty and communication are key to the success of a team and of a business.  She is ecstatic to join the SunSource family!

Amie Clarke

Business Development RepresentativeKristen Thomas Pic

Who says sustainability has to be all about Birkenstocks and chewing on sticks? Having resided in community-based living environments including Villa Grove, Illinois and Nak Nek, Alaska, Amie adopted a great appreciation for the freedom and camaraderie that lends itself to a low-impact way of life. In her many travels, she encountered humans who value sustainability as a pseudo religion; it’s their way of life. Honestly, Amie is not one of those people, but would like to begin applying some of the practices that she valued in said humans. 

While living in Chicago for six years, Amie reaped the benefits of public transportation and fell in love with biking. This vehicular freedom allowed her to explore a variety of neighborhoods and homes in and around the city.  New initiatives and implementations of live roofs, community and rooftop gardens, shared cars and bikes, bike taxis, beer growlers, grey water procurement and storage, repurposed materials, and solar, to name a few, intrigued her. After moving back to her hometown of Kansas City, she realized her next job had to be something that she valued. With experience in landscaping, working in corn fields, educational sales, marketing and stand-up comedy, Amie is looking to help to make an impact by encouraging education and humor in all realms and is now ready to take a stab at sustainability and solar power.  With a passion in communicating and helping people to better their lives, Amie joins SunSource!
