Sure can. I’ve known Dave for over 25 years. His nursery is in Kelley, Iowa, just south of Iowa State University. it’s on an 800 acre farm, beans and corn. I bought my first trees and took my first bonsai classes from him, when it was Dave’s Aquarium and Greenhouse. Still have my notes! He had tropical fish and tropical bonsai in a weird lean-to he built by knocking out a wall in his basement, and enclosing it with a poly top, but it had cinder block and dirt walls. The place gave my girlfriend (now my wife) the creeps, but I was pretty hooked.
Over time, I think he enjoyed propagating plants and making pots more than refining trees. He especially likes those “eggshell” and “scoop” pots. He has a couple signature styles that he calls Special Process and Fossil.
He was married to Sue a couple years after I met him, changed their name to DaSu Studios, and got pretty heavy into making pottery. Sue was really good at marketing him and she put his business online really early on, in fact his website is bonsaitrees.com and I’d imagine he's been offered more than a few bucks for that domain over the years.
Haven’t seen him in about 5 years, but not much had changed; overrun with propagating plants, still firing pots and making stands on the farm.
