Sheri, a Registered Architect in the State of Connecticut, has extensive experience in design and project management, having practiced architecture for nearly 30 years, with a primary focus on green projects since 2001.  Her vast experience in the building industry is further enhanced by completion of a Graduate Certificate in Sustainable Design from the Boston Architectural College / Sustainable Design Institute in 2011.  She earned both a Bachelor of Architecture degree and Bachelor of Fine Arts degree in Interior Architecture from the Rhode Island School of Design.

In 2002 Sheri earned the distinction of LEED AP® (Accredited Professional) and in 2011 added the specialization of BD+C (Building Design + Construction) to this credential.  The LEED certification program, developed by the USGBC (U.S. Green Building Council), is the nationally accepted benchmark for the design, construction, and operation of green buildings.

Sara Dodson Holmes, Secretary

While her decision to attend Skidmore College as an undergraduate may have been heavily influenced by its outstanding equestrian program, it was here she fell in love with theater, soon becoming involved in all aspects of stagecraft. Knowing she wanted to follow a career in architecture and design, Sara earned a Bachelor of Science with a self-determined major incorporating studies in technical theater, art history, and studio art.

At the University of Pennsylvania, Sara’s studies ran the gamut from historic preservation to environmental building simulation eventually earning a Master of Architecture at the Graduate School of Fine Arts (now called the School of Design).

Sara has been with Wyeth Architects since 2009 working on numerous residential and institutional projects. Prior to this she worked at Centerbrook Architects and Planners in Essex, CT where she was involved in many different project types including museums, independent schools, student centers, research laboratories, and athletic centers.

Sara is passionate about sustainability and is a LEED professional and recently earned her Passive House certification (Certified Passive House Designer). Her dream home is a converted barn.

Phillipe Camus

I became a Certified Passive House Consultant (CPHC) at the end of 2011. It was my most demanding accomplishment since receiving my architect’s license in Connecticut in 1982.

I initially earned a diploma of Architect from the Ecole Nationale Supérieure d’ Architecture in Belgium, where I grew up. Afterward, I received a Master’s in Environmental Design at the Yale University School of Architecture.

Then I started designing houses, including several passive solar homes, was a contractor for a while, and for a few years worked for other architects until I opened my practice in Branford, Connecticut in 1986.

I have continued training, taking courses at the Harvard Graduate School of Design, among others. I am now certified by both the US and by the International Passive House Institutes, and a member of the New England Sustainable Energy Association. In addition, I am a registered Interior Designer.

Community involvement, another aspect of my career, has led me to give several lectures on renewable energy, both in Connecticut and in Belgium, to co- chair the AIA, CT’s Committee On The Environment for several years, and for a few years recently, to chair the Town of Guilford’s Design Review Committee.

Now, I specialize in Passivehouses and remodelings, all the way to Net Zero; and in “Near Passive houses”, that foster greater comfort and healthy indoor air quality, using very low-energy, including renewable sources (geothermal and solar), which also reduces the carbon footprint. It is often the better alternative for the projects I do on sensitive sites.

My latest Passivehouse won the 2015 Hobie Award for the “Most Energy Efficient house” in Connecticut. I have also designed many medical and professional offices, several restaurants, many condominiums and even renovated a state prison. Moreover, I have an excellent track record of getting variances for properties with difficult zoning problems.

Houses I designed are in various states including: Connecticut, New York, Massachusetts, Colorado, as well as in the US Virgin Islands, France, and Belgium. Some of my work has been published in This Old House, Food and Wine, The Hartford Courant, The New Haven Register, and Yankee Magazine.
