Greenport Designs
We're two brothers, Jacob and Eli Froneberger, who grew up in wonderful Marin County where we still reside and call home. Growing up amongst such gorgeous surroundings inspired us to create more beauty in the world ourselves. We both loved working with our hands and had a good eye for design and style.

In 2014, we formed our vision, rented our first shop, and began building functional works of art for homes, commercial spaces, and some of the fantastic restaurants and wineries in the area. We realized within just a few years the great demand in Marin County for quality craftsmanship, and with a little hard work and determination, decided to expand, hire a crew and make it official.

We had a very small project, however, I was nervous about all it would entail to fix the problem. Eli and his team were attentive to my concerns. They offered an array of options and always kept my budget top of mind. Everyone was a pleasure to work with. They were able to fit me in right away and even finished the project early!

I asked Greenport Designs to bid on moving a bathroom. The bid itself was good in terms of amount, but what impressed me most was the careful way it was broken down between each section of the job for both materials and labour. I knew exactly what I was paying for and what I was getting I ended up not moving the bathroom but repairing the old one, a smaller job and one they finished perfectly. Each step was done thoroughly and neatly and the whole job was finished a day earlier than originally quoted. Even more surprising was the response of my tenant who complains every time I let a repair

I had a fence/ gate that I wanted built and I was super nervous about it and no idea who I should call . Well I was referred to Greenport thru a friend and I could not be happier with the work they did ., a gentleman by the name of Duane came over gave me an estimate and some suggestions regarding the fence and it turned out gorgeous!! Thank you Duane for making this a pleasant experience, done on time and the price was right ! Thank you thank you

I cannot thank Greenport enough for helping me create the space of my dreams. When I came to Eli and Jay in early 2016, I was discouraged by my family's opinion of building open shelving throughout my kitchen. I wanted a wrap around top shelf and my family disagreed, saying it would close off the space. Eli and Jay met my concerns with a logical approach, further creating a vision I could never see for myself. Their enthusiasm for my project fed into every facet of my home and before I knew it I had three custom shelf units made of walnut for my kitchen, a beautiful pine bar-type desk, and
