About Integrity


Integrity’s reputation for fine craftsmanship and exceptional customer service has been recognized in the Pioneer Valley for over 25 years.

“Integrity” is more than a name. It’s our promise, and it applies to the designs we create, the financial expertise we demonstrate, and the exemplary service we deliver with every job.


Integrity was originally founded in 1991 by Peter Jessop. Integrity’s first mark in the Pioneer Valley came with the completion of 32 homes in Amherst in 1994. This development, known as the Pioneer Valley Cohousing Community, was one of the first communities of its kind in the eastern United States. Each home was customized to accommodate unique and elaborate buyer preferences, all of which Integrity completed on budget and within schedule.

In 2012, Peter Jessop formed a partnership with Heidi Flanders and Anna Novey Cook, ensuring the longevity of the quality craftsmanship and exceptional service Integrity clients have come to expect.

Since, Integrity has met the new construction and remodeling needs of hundreds of homeowners, small businesses, educational institutions, and multimillion dollar corporations. Some of our most notable projects include:


Anna Cook, Owner and Principal Project Manager

Anna coordinates with Integrity’s clients, designers, field staff, subcontractors, and architects to ensure each project transitions seamlessly from planning through construction. She is a licensed construction supervisor and a Certified Lead Renovator (RRP).

Anna began working at Integrity in 2002 while completing her Bachelor of Science degree in Building Materials and Wood Technology at the University of Massachusetts, Amherst. After living in one of the oldest homes in South Deerfield for seven years, Anna now lives in Shutesbury, MA with her husband, Tim, and two daughters.

Heidi Flanders, Owner and Principal Designer

Heidi’s thorough knowledge of materials and costs, combined with her keen ability to assess clients’ needs, makes the project design process exciting and efficient. Heidi is a Certified Lead Renovator (RRP) and is a Certified Aging-in-Place Specialist (CAPS), which enables her to effectively address the changing lifestyle needs of an aging population and support design sustainability.

Heidi joined Integrity in 2008. Prior, she was a designer at a local post-and-beam company. She graduated from Keene State College with a Bachelor of Science degree in Industrial Technology, specializing in Residential Architecture, with a minor in Occupational Safety. Heidi is a lifelong resident of Conway, where she lives with her husband, Jon, and their two daughters.

Kyle Belanger, Project Manager

Kyle was majoring in Building Materials and Wood Technology at UMass Amherst when he began his building career at a local lumberyard. He spent a semester interning at Pioneer Valley Habitat for Humanity, before graduating with a bachelor of science degree in 2008. During his years at the lumberyard, Kyle sharpened his skills in sales, estimating, and engineered wood design while forging strong relationships with customers and suppliers. As project manager at Integrity, he guides clients through their projects’ design and building phases with the know-how gained from a good education, a solid work background, and plenty of hands-on experience. His extensive product knowledge ensures that our clients get the right products at the price that suits their budgets. Kyle is a native of Belchertown, where he currently resides.

Nicole Wetherell, Designer

Nicole graduated in 2017 from UMass Amherst with a Bachelor’s degree in Architecture and a minor in Building Construction Technology. While earning her degree, she participated in a four month design-build program in which students designed and constructed a 600 square-foot library/tiny house in four months. She also volunteered with UMass’s chapter of Habitat for Humanity and earned a LEED certification her final semester. As a Project Designer, Nicole assists with architectural drafting and produces presentation materials and renderings.

Field Staff

Integrity has a staff of skilled carpenters and a full-time painter, and half of these dedicated employees have been with the company for 10 or more years. Their combined skills include framing, hanging and taping drywall, installing cabinets and fixtures, replacing windows, roofing and siding, trimming, painting, and more. Our field staff’s goal is to leave the client with a beautifully crafted home and a good impression. Employing our own field staff ensures we have an experienced and conscientious crew at every work site, enabling us to consistently meet our project deadlines with confidence.
