Armando Covarrubias Jr
-
Armando Covarrubias Jr is a furniture maker originally from Arrey, New Mexico. After many years working in the food science and agriculture industry with his family, he decided to change careers and attend the Wood Design: Furniture Making program. He builds custom-made furniture by combining hand tools, craftsmanship, and modern machinery.

Alexander Grabovetskiy was recognized as the 2012 International Wood Carver of the year, and his piece Wall Decoration was awarded first place. His work utilizes the same approaches used for centuries by master woodcarvers, including techniques employed by Grinling Gibbons. In 2015 Alexander Grabovetskiy was Editors’ Choice to be Awarded with Woodworking Excellence in category: Turnings, Carvings & Objets d’Art by Popular Woodworking Magazine.
Grabovetskiy was born on July 4, 1973, in the Russian town of Dimitrovgrad. His grandfather taught him basic woodcarving techniques at six-years old, and at 16 he was taken on as an apprentice by renowned carver Vladimir Tokarev. Due to his faith and his refusal to enlist in the Soviet Armed Forces, Grabovetskiy was imprisoned by the Soviet authorities. He was freed after two years as part of an Amnesty International campaign for prisoners of faith incarcerated by the USSR. In prison he began a business making furniture and kitchen sets, and finding no work upon his release at the age of 21 years, he continued on to run his own woodworking enterprise.
In 1996, Grabovetskiy immigrated as a political refugee to the United States together with his wife Nadia and their 10-month-old son. The woodworking and custom home building business that he established in Goshen, Indiana, Aalmark LLC, employed a number of expert craftsmen who were also Christian refugees from the former Soviet Union.

Since then, he has built and restored a variety of timber frame structures, many of which are working barns and agricultural buildings on small, family-owned farms. Ethan specializes in hewn, scribed, and full-round material, and has adopted a mission to not only promote the craft of timber framing, but also to work in line with the vision of what the world can look like when care is put into the food we grow, the buildings we construct, and the work we do every day.
Jaime Marvin
-
Jaime Marvin grew up in a historic home in Metamora, Michigan, where a love for craftsmanship took root early. Always by her father’s side, she learned woodworking, metalworking, and how to fix or build just about anything. Music became another lifelong passion—Jaime played multiple instruments, earned a Master of Luthiery Certificate in 2003, and eventually purchased the local music store where she once worked. She transformed it into a thriving community space offering lessons, repairs, and live performances.
In 2020, Jaime developed a neurological disorder that affected her right hand and ended her ability to perform music. That loss marked the beginning of a new chapter. She became a Master Gardener, earned her Michigan Builder’s License, and in 2025, graduated from the Wood Design program at the Sam Beauford Woodworking Institute, earning the Red Seal Award for most outstanding student. Jaime has since built her own workshop and is excited to see where her journey of craftsmanship and creativity will lead next.

Joe Miller
-
Licensed P.E.in MI, WI, MN, KS, MO, IN, IA, NC, GA, OK, TN. P.Eng. in BC, AB, and ON.
In 2009, before the ink dried on Joe’s Ph.D., he joined the Fire Tower team, where he will continue his groundbreaking work on keyed beams.
Joe’s interest in timber framing grew from a project he took on with his father, rebuilding an ancestral barn in southern Indiana. In Joe's freshman year at the Rose-Hulman Institute of Technology, he attended a lecture by Ben Brungraber. Ben must have said something inspiring, because Joe ventured forth on an ambitious track that eventually led to a Masters in Civil Engineering at University of Wyoming. While in school, Joe conducted innovative research on the strength of wooden dowels - findings that significantly advanced the acceptance of timber frame construction among engineers and code officials.
Masters degree in hand, Joe had a two-year stint with Yankee Barn Homes in New Hampshire, doing engineering, lateral analysis, drafting and frame design. Next came a spell with Trillium Dell Timberworks in Illinois, where he refined his design, engineering and cutting skills in the shop. Meanwhile, Joe sought out a school where he could undertake intensive research on key laminated beams. Michigan Technological University gave him the green light, and now Joe has a Doctorate of Philosophy in Civil Engineering for his analytic methodology for the design and engineering of keyed beams. Concurrent to his advanced studies, Joe privately consulted on timber frame designs and taught on-line courses for Norwich University in Advanced Structural Analysis.
Joe’s trailblazing through the industry has led him to Fire Tower, a team that shares his passion for extending the reach of solid sawn timber.

Daniel Schuck
-
Within the vast, velvet-green Pine Barren forest of southern New Jersey, Dan’s admiration for nature was formed and fostered. His countless hours spent among the trees and natural beings planted a seed for an ever-expanding love and connection to the natural world. After about fifteen years spent making a career in the hospitality industry, he found himself in the San Francisco Bay Area. Here, amongst the towering redwoods and reaching coast live oaks, Dan felt both a deeper relationship with natural materials fostering and a desire to introduce a slower, more hands-on pace & practice. What began as a few rudimentary furniture projects around the house, soon grew into an educational pursuit at Laney College’s Wood Technology program in Oakland, CA. In 2017, after completing the program, he began an eight year journey with Brimer Workshop in Richmond, CA - moving from assistant to Head Fabricator - building and installing high-end custom furniture and cabinetry for clients throughout the Bay Area. While learning to draft his first projects in 2014, Dan became acquainted with the 3D modeling program Sketchup. Captivated by the ability of this program to turn thoughts & ideas into detailed, workable plans, he began sharpening these skills with commissioned and personal furniture projects. He furthered this pursuit as the in-house drafter of all shop drawings at Brimer Workshop. In 2025, Dan relocated to a 4-acre farm house in the River Raisin watershed and became acquainted with the Sam Beauford school. Dan has recently joined the program as Sketchup Instructor and, with gratitude, looks forward to deepening his relationship with both the students and the school in years to come.

Nathanael Ulfers
-
Nathanael Ulfers is a Virginian woodworker and timber-framer, specializing in vernacular architecture and early methods of the craft from his own region of the Chesapeake and to an increasing degree, all over.
A deep interest in architecture, a propensity for pre-industrial craftsmanship, and a very wise grandmother set the course at childhood. Early experiments and hungry research led to great opportunities in the bountiful field of historic restoration. Here in the land of first presidents, Nathanael sought out and learned from the best in the field on the likes of Mount Vernon, Montpelier, and many other great early American houses over the years.
In the time since, Nathanael has traveled all over the east coast for clients such as the Classical American Homes Preservation Trust, and all the way to Japan to move a Meiji Era farmhouse to the western hemisphere. Most recently, Nathanael has been working in Jamaica as the lead timber-framer on a large project involving many structures designed and built using historical materials and methods of Jamaica.
When he isn't on the road or lost in an airport, Nathanael can be found buried alive under his own personal projects in a 1750s-built Virginia hall-and-parlor just east of Fredericksburg, with his wife (an expert in historic textiles) and young son (an expert in excited incoherent babbling).
Nathanael is a contributor to the Traditional Timber-framing Research and Advisory Group of the Timber Framers Guild and teaches workshops for preservation students of Mary Washington University, the American College of Building Arts, and has been instructing at VMI's biannual FTX timber framing workshop since 2015.
