Erich Heidenreich, DDS, PLLC
We are conveniently located right in the heart of historic downtown Marshall two doors east of Hemmingsen's Rexall Drug Store on the
side of Michigan Avenue. You can park in the free city lot in back of the office and use our rear entrance if you like.
Dr. Heidenreich's office is located in Marshall’s National Historic Landmark District. Built in 1874, the structure is one of only two remaining storefronts of the original "Cook Block". Over the past century, this building housed mainly clothing stores. Second floor dental offices were common a century ago, and the second floor of this structure was occupied by "Doc" Durand.
The present storefront resulted from remodeling in 1921. Dr. Heidenreich restored this façade in 1988 using a unique alternative to sandblasting, which would have ruined the surface of the soft upper brick. The painted, deteriorating surface was chemically stripped and the mortar restored.
The leaded glass panes above the show windows were uncovered by Dr. Heidenreich during the 1988 restoration. These "Luxfer Prisms", designed by Frank Lloyd Wright, act in concert to flood the interior of the building with light at mid-day. Especially affected by this phenomenon is the ornate tin ceiling, as all of its patterns are revealed in beautiful contrast by the horizontally directed beams of sunlight.
The present floor plan, designed and constructed by Dr. Heidenreich, lends a comfortable openness to the dental office. The angled walls, and colonial six-panel doors are trimmed from top to bottom with over 1,250 feet of wood trim. Soft grey, blue, and mauve tones add to the calming nature of the office, which also displays a unique collection of late 1800’s dental equipment, including a foot powered dental engine.
