Our Team

Frank Wetenkamp

Frank started working as a carpenter while in high school. He graduated college with a degree in Civil Engineering and a minor in Architectural studies. A Natural Building course at Yestermorrow Design Build School set him up for a move to Colorado and an apprenticeship with Ryan Chivers of Artesano Plasters. When he isn’t building, Frank likes to snuggle cats, go camping, hike, and mountain bike.

Cheryl Corsiglia

Cheryl got into the construction industry through an internship with Community Rebuilds, building a straw bale home in Moab. An Earthen Building course in Nicaragua led to some connections to the natural building community in CO. Being a tradesperson runs in the family: her grandfather designed and built houses in Florida. She is on the board of the Natural Building Alliance. Most weekends, you’ll find Cheryl rock climbing, a hobby that has taken her to many beautiful places.

Marj Russow

Marj comes to building through disaster relief work. After high school, she spent some time demolishing and rebuilding damaged homes in Mississippi after Hurricane Katrina. Before joining our crew she worked at a horse stable, also taking riding lessons. Her dream is to own her own land and stables. She has a well-rounded pet family, including a dog named Daisy and a snake named Rhonda.

Gary Kainz

Gary is a carpenter, builder, and general jack-of-all-trades. Always tinkering and making things, he has been building professionally since 2018. Gary spends his free time on the farm, raising animals, fixing and building things, and spending time with his wife, dog, and two cats.


Maki is the newest team puppy. She is a social butterfly who came to Colorado from a Gallup, NM. Maki likes all people, all dogs, all other animals, birdwatching, pretty much every toy, chewing on things, going to puppy class, and training.


Lady is still young, but she loves the job site atmosphere and is always excited to see everyone at our team meetings. She loves running around and playing with humans and especially other dogs. Lady is also a gentle and kind older sister to her family’s human baby.

What Our Clients Say

Everything you want in a contractor

Ben, Frank and Cheryl were a pleasure to work with on the project. Our plan was to alter a brick wood burning fireplace with a gas insert and to redefine and modernize its appearance and shape. Our first thought was concrete, which proved to be too heavy and expensive. Living Plasters’ suggestion of a finish …

Pride in their craft

We couldn’t be more pleased with our experience with this dynamic team of professionals. We hired them to build out our unfinished 1000 sq. ft. basement. Ben put together a comprehensive estimate, finding competitive bids for the electrical, heating, plumbing, and drywall portions, plus concrete floor stain & polish. We were pleasantly surprised to find …

My favorite room

I am really pleased with my clay walls. The clay surface creates such a soft beauty full of subtle variations in tone and texture. Their natural, earthen feel gives the room a unique ambience. It’s now my favorite room in the house. Ben and Ethan were a great team and really worked with me to …

Beyond our expectations

We highly recommend Ben Waldman. His outstanding workmanship and professionalism were beyond our expectations.  Reliability, honesty, consideration and attention to detail were several of the qualities Ben demonstrated.  We will certainly call him if we need to have more work done in our home.

Ben Waldman and his crew were delighful to have in our home for 7 days; polite, friendly, conscientious, efficient, and hard working. They cleaned up every day, and all the work they did was superior. Ben is a thoughtful and fair businessman, who does what he says he will do, when he says he will …

Wonderful craftsmen

Ben and his partner who remodeled my small bathroom in my 80 year old house are wonderful craftsmen who designed a beautiful room that incorporated the elements I was looking for while suggesting adjustments that made the best use of the small space. The room had given me moisture and leakage problems for 25 years …

A gorgeous upgrade

Frank, Ben and team plastered a large portion of the inside of our house in Lyons over a four month period in 2016. This was over 3500 sq. ft of floor space with vaulted ceilings, rounded arches, and extensive trim work. The craftsmanship is incredible and the end result was a gorgeous upgrade to our …

Their art is a pleasure

We have been living in our straw bale house for two years. Every day we enjoy the beautiful artistic work Frank, Ben, and Cheryl did plastering the walls and applying the tadelakt technique in our bathroom and along our kitchen counters. Their art is a pleasure for the eyes and to the touch. Tadelakt walls …
