Built in 1889, this housed served as home and practice for early Arvada doctors. Harry T. Hallock practiced here until 1902 when he sold his home and practice to Dr. Richard Russell. Dr. Russell also operated a drug store which was located next door to his home. This was the first location of the H.A. Ullery Drug Store. In 1907 Russell sold his home and practice to Dr. E.L. Foster who remained and practiced here for 60 years. Foster was a typical "horse and buggy" doctor, making house calls in his buggy drawn by "Siegal", his favorite horse. The carriage house still stands in the back of the house.
