Adam Lans

I’m originally from New Rochelle, New York, and received my Bachelors of Architecture from Carnegie Mellon University in Pittsburgh, and moved to Seattle Washington immediately after schooling to learn about the booming building industry. I worked in construction for years in Washington as an alternative to pursuing traditional architecture in an office. This helped me integrate trade skills with knowledge of design and architecture.

I started Tight Knot Design Build to bring my design and trade expertise to my community and to build long lasting relationships with the people here.

Patrick Binder

I spent a decade managing crews and project of various sizes in southern California. I have experience in every phase of the construction process and getting the job done, as well as managing the many moving parts of a service business.

I’ve teamed up with Adam and Tight Knot Design Build to bring better construction and design to my community.

I am also on the board of, and volunteer regularly with, We Heart West, a non-profit benefiting the communities of West Manchester.

Mari Fontaine

I spent the first ten years of my construction career working at a mid size roofing company in Southern California. I focused on business operations including safety, project management, business development, and accounting. More recently I’ve developed my skills in the field so that I can better estimate and manage crews to get your job done right.

I moved to New Hampshire in 2017 and have grown to love this community. I am excited to be building beautiful projects throughout the region.

I am also on the board of, and volunteer regularly with, We Heart West, a non-profit benefiting the communities of West Manchester.

As a Partner at Tight Knot Design Build I aim to offer quality service and craftsmanship to every project we work on.
