1331 Grand Avenue

The building

The two-story building on Grand Avenue. Our practice is on the upper level; the parking entrance sits below. We share the address with The Oldershaw Clinic — look for our sign on the railing.

Up the walkway

The approach

A planted walkway runs along the side of the building from the parking area to the front entrance. Year-round flower beds and herb planters line the path.

The waiting room

Compact, daylit, calm

Two armchairs and a sofa rather than rows of clinic chairs. Plants on the windowsills, framed photographs on the walls, a quiet corner desk. The room is intentionally small — most patients are called back within a few minutes of arrival.

Treatment hallway

Into the operatories

The hallway behind the front desk leads to four operatories and the imaging room. Each treatment room is numbered (you can just see room 3 at the end of this hall).

An operatory

Where treatment happens

Inside one of the treatment rooms — chair, overhead operating light, integrated sink, and the panoramic window above the chair. Each operatory is set up identically.

Digital panoramic imaging

Lower-radiation X-rays

The panoramic X-ray unit captures the entire upper and lower jaw in one rotation. Digital radiography reduces radiation exposure by 80–90% versus traditional film and produces instant detailed images — used heavily for treatment planning before implant work.

The outdoor patio

End of tour

Off the back of the practice — a small private patio with planters, table seating, and the view back toward the operatories. End of tour. When you're ready to see it in person, book a visit below.
