                                   During his residency at the University of Oregon,
                                   the Koller family developed a special affection for
                                   Oregon and have spent considerable time in the central
                                   Oregon area. This and a desire for a lifestyle
                                   change has brought the Koller family (wife Peggy
                                   and sons Jeffrey and Carson) to Bend seeking a
                                   less urban environment, more outdoor recreational
                                   opportunities, and a milder winter.
