Mulgrave Road doctors' practice is the oldest in Sutton and founded by Dr William A Hearnden MD who qualified in 1859. He began his practice at Lys Cottage in the High Street and then moved to Down House at 80 High Street. This was also his home where he lived with his large family and servants. Two of his sons, William who qualified as a doctor in 1880 and Earnest who qualified in 1888 joined him in the practice. His niece acted as the receptionist. They are said to have owned the first car in Sutton.
After WW1 the practice moved to Stafford House on Church Road where the Civic Offices now stand. It moved again in 1936 to Danesboro' on Sutton Park Road and in 1965 it moved to its present premises at 48 Mulgrave Road. Originally the practice occupied only the downstairs of this homely Victorian building. In 1988 two consulting rooms were added to the side of the property and in 1993 the practice was extended upstairs to provide extra surgeries, a waiting room and office space. Finally in 1999 the downstairs waiting room and reception were extended.
