Hugo studied in Tokyo with Japanese bonsai master Kunio Kobayashi, one of the most respected and well-known bonsai masters in the world. Since completing his apprenticeship in 2015, Hugo has made several return trips to Japan to continue his work at Shunkaen Bonsai Museum. Returning to Tokyo with Mr. Kobayashi on a regular basis has allowed Hugo to continue to build, refine, and expand his skills. Hugo was a demonstrator at several important international bonsai events including the Latin American Bonsai Federation Congress and the 2022 World Bonsai Congress in Australia. Hugo’s travels have allowed him to acquire a broad knowledge of conifers, deciduous, tropical species, deadwood, compositions, and landscapes from the most classic and orthodox to new and creative trends.

Suthin’s artistry continues to amaze. Suthin and his wife operate the Royal Bonsai Garden in Stoughton, Massachusetts and he is in high demand nationally for his creativity, his spectacular artistry, and his skill as a patient and talented teacher. Born in Thailand, Suthin has extensive experience with tropical bonsai. To label him as a tropical bonsai artist, however, would do tremendous disservice to the equally amazing Japanese maple, juniper, azalea, and pine (among many other species) bonsai, both large and small, he has cultivated and designed. Suthin’s creations have won multiple well-deserved national bonsai awards in both Thailand and the United States. He lectures all around the world and at some of the most important bonsai conventions in the United States, sharing new information and techniques whenever he teaches. His bonsai are known for their proportion, refinement and detail, especially his remarkable Shohin designs. Suthin and his wife operate the Royal Bonsai Garden outside of Boston, Massachusetts.

Ken started Bonsai in the late 1980’s beginning with the Cleveland Bonsai Club and taking workshops from the formative artists of American bonsai including John Naka, Yuji Yoshimura, Susumu Nakamura, Dennis Makashima, and Vaughn Banting. As Ken’s interest grew, he launched Ken’s World of Bonsai in North Canton, Ohio to supply the local bonsai community with quality trees and supplies. Teaching came later, after requests from groups and clubs eager for more information. Ken continues to learn and grow, traveling twice to Japan and around the country visiting other bonsai clubs and growers. Ken enjoys working on all types of trees and loves sharing what he’s learned as a grower, artist, and teacher.

Teresa is a ceramic artist from Holland, MI, with over twenty years of experience as a professional potter. Originally a watercolor artist, she created and marketed functional and fine-art ceramics on the midwestern art show circuit, specializing in hand-carved “sgraffito” designs with sculptural elements. As a master gardener and nature lover, it was only natural that she was drawn to the art of bonsai. In 2018 she began studying bonsai in earnest and switched to making bonsai ceramics exclusively in 2020. All her work is individually crafted without the use of molds, making each piece completely unique. Her work is both wheel-thrown and hand-built in both stoneware and porcelain, often with sculptural elements, hand-carving, and hand-painted embellishments and finished with her own unique glazes. She works in a sunlit studio attached to her home, surrounded by gardens and woodlands near the shore of Lake Michigan, and markets her bonsai ceramics through her website, www.stoneforestpottery.com, online through bonsai auction sites, and at a few local bonsai shows.
As with many people, Eric’s first exposure to bonsai was The Karate Kid. His experience, however, began when he was gifted two bonsai trees; a ficus and procumbens juniper in 1998. When neither survived, Eric dove in head first to learn what he did wrong and his bonsai journey began. When Eric relocated from his native woodland environment to a more urban setting, bonsai became a way to keep nature a part of his life. He began reading everything he could on the subject, joined the Bonsai Society of Kalamazoo and started taking workshops whenever possible. Eric counts Ben Oki, the club sensei, and Jack Wikle, the presenter at his first club meeting, as key positive motivational influences and counts his club experience as a major contributor to his bonsai education. Eric began sharing his knowledge with others at both local clubs and the Michigan All State show. As the current President of the Bonsai Society of Kalamazoo and through his position for a Japanese company, Eric has fully embraced the kaizen culture (continuous, small, incremental improvements) both for the trees and himself. He regards bonsai as a lifelong learning experience and loves to share his knowledge and to learn from the insightful questions that often accompany teaching.
In addition to his many other roles, Chuck Barker is the owner of the StoneView suiseki, viewing stone, and bonsai gallery in Chicago. He came to own and act on this vocation beginning with years of instruction in bonsai cultivation and design from his first teacher, Ivan Watters. Chuck subsequently worked with Susumo Nakamura, Jim Doyle, Jeff Schultz, Bill Valvanis, Jay Strommen, and his first suiseki teacher, Sean Smith. Sean’s generous personal instruction, guidance, and leadership in organizing the International Stone Appreciation Symposia, opened up the world of suiseki for Chuck. Through the symposia, he met scholars and art professionals with a similar passion for suiseki. He joined Aiseki Kai, benefitting from the legacy and enthusiasm of that wonderful group of colleagues led by Larry and Nina Ragel and the Huntington Museum. Chuck continues his studies, voraciously consuming books, attending museums and exhibitions, and engaging new teachers, collectors, scholars, daiza carvers and collecting sites worldwide. Chuck is extremely active, exhibiting stones nationally and internationally, hosting literati groups, teaching about the collection and display of suiseki and viewing stones, displaying and selling stones through StoneView, and fostering permanent collections open to the public. He is deeply grateful to the many good friends and enthusiastic members of the international suiseki community; and for the mountains, rivers, oceans, deserts, water, wind, and sand that yield up their treasures for our enrichment and inspiration.

Jimmy’s love of plants developed during his youth as he grew up around family farms. He discovered bonsai as a young military officer traveling the world and found that it neatly combined his passion for plants with his creative and design background.
