WholeTrees® builds prosperous relationships with forests and communities

WholeTrees® brings the abundant waste stream of healthy forest management to high-value construction markets. We supply to and catalyze the growing restorative building movement. We strive to add value to sustainable forestry to preserve and foster the awe and delight of our woodlands.

Our commitment of innovative and profitable use of forest byproducts is demonstrated by:

  • Excellent track record and trusted brand
  • Proprietary products
  • Scalable production technologies
  • Proprietary engineering processes and researched design values
  • Digital inventory and future customer-facing software platform

Round timbers have many social, environmental, and economic benefits. WholeTrees’ local and regional supply chain continues to grow into a distributed production model that limits transportation costs, reduces embodied energy in construction, and benefits rural economic development where raw materials are sourced and fabricated. Round timber is abundant and rapidly renewable: trees as young as twenty years, which are often unusable in conventional forest products industries, can be used to create small diameter round timber structural products. WholeTrees’ harvest processes encourage sustainable forestry practices such as thinning, which restores our woodlands by reducing invasive species, disease, and risk of wildfire.

Baxter leads her executive team toward both scale and innovation. Baxter has over a decade’s experience in market development, HR, and operations in numerous agricultural and land management projects. Throughout her career, Baxter has specialized in managing short and mid-term systems to reach long term goals, while attracting talented teams that build organizational capacity and successful momentum.

R+D Programs Manager

Michaela Harms

After completing a university work placement with WholeTrees in 2014, Michaela has returned to the team to manage WT’s research grants. She graduated from Metropolia UAS in Helsinki, Finland with her BSc in Civil Engineering focused on Sustainable Building Engineering. Her thesis on the potentiality of building-integrated photovoltaic energy for southern Finland received a Nordic GBC award for innovation. With her roots in natural building, Michaela hopes to continue the advancement of renewable structural design through research and development. She is an avid backwoods explorer, sauna advocate and team trivia connoisseur.

Lead Foreman

Robert Mini

Robert joined WholeTrees in March 2008 as an entry-level carpenter and has grown into a lead foreman and our go-to artisan craftsman with gusto. His attention to detail and ability to execute detailed projects in scales as small as serpentine wood benches to as large as entire commercial structures remains a huge asset to WholeTrees’ functionality. Rob has studied and built bamboo structures in Hawaii, bringing knowledge of re-purposing invasive wood species into viable round timber structural components. Elusive Works is Robert’s thriving art studio where he crafts wood-turned bowls and large-scale murals.

Lead Project Designer

Autumn Cartee

Autumn joined WholeTrees in 2018, bringing with her a background in Interior Design and Remodel Project Management.

Professional CEUs and Presentations

WholeTrees is certified to provide continuing education for AIA and GBCI professionals. Why Trees are Stronger than Wood is an intriguing presentation that will provide your team with a better understanding of round and mass timber in ancient and modern construction. 

At the end of this course:

  • Participants will be able to name 3 types of historic structures built using small diameter timber
  • Participants will be able to name a benefit to the forest ecosystems or regional economies of building with small diameter timbers or other mass timber technologies (CLT)
  • Participants will be able to name a performance benefit of using small diameter timber structural system in bending strength, fire rating, fire failure mode, and life cycle performance
  • Participants will be able to quote a new learning of building with small diameter timber found in destructive testing at the USDA Forest Products Lab

Would you like to learn more about specifying WholeTrees into your projects for upcoming clients? We would be happy to provide a lunch and learn for your staff. Contact us with your needs for an educational session in person or via webinar.
