Maggie DiUlio and Jim Klaassen, DVM, are a husband and wife team that value uncompromising quality, natural beauty and personal creativity.  These values are obvious in the development of Casa de Arboles, Fine Fiber Farm.  Their breeding program for huacaya alpacas emphasizes the development of the finest alpaca fleece carried on classic Peruvian white huacaya alpacas with substantial size and excellent conformation.  The ultimate breeding goal of Casa de Arboles is to realize Don Julio Barreda's vision of the 20-20 alpaca; twenty pounds of fleece sheared at 20 microns diameter.  The Accoyo ranch has many descendents enjoying their lives at Casa de Arboles.
