Is Gregory W. Olson, DDS PLLC independently owned or DSO-affiliated? The ownership of Gregory W. Olson, DDS PLLC is not yet verified in our records. We classify offices as independent, group, or DSO/corporate-affiliated from primary sources.
Privately owned is not the same as independent. A licensed dentist can own a practice on paper while a Dental Support Organization (DSO) or corporate group runs the business. We classify by management affiliation, not ownership title.
Classifications are based on available public information and reviewed submissions, and are not legal ownership determinations. They may be updated as new data or corrections become available.
