About Us


Located on the campus of North Ottawa Community Health System at 1445 Sheldon Road, Harbor Dunes houses primary care and specialty physician offices, a retail pharmacy, rehabilitation, laboratory, bone densitometry and x-ray services. A corridor connects Harbor Dunes to the main entrance of the hospital for easy access between the two buildings.

All of the offices in the building have common customer service and medical goals, which makes patient experience seamless – no matter who you are here to see or what service you need. Among these common goals are: universal insurance plan acceptance, common referral protocols among practices, valet parking for those in need, and customer service ambassadors to help patients and visitors who require additional assistance.
