ABOUT SENTINEL OPERATIONS GROUP

Operational Discipline for Independent Dental Practices.

Sentinel Operations Group brings decades of operational experience to the business side of independent dentistry. Founded by Darryl Colbourne, Sentinel helps practice owners approach business decisions with greater clarity and structure.

WHY SENTINEL

Built for the Business Behind the Practice.

Dentists spend years mastering clinical care. But running a practice means much more — people, operations, finances, compliance, and long-term decisions that impact your team, your patients, and your future.

Sentinel was created by Darryl Colbourne to give independent dental practice owners an experienced operational perspective for the business side of their practice.

“Stronger practices build healthier communities.”
— DARRYL COLBOURNE

MEET THE FOUNDER

Darryl Colbourne

Founder & Principal

Darryl brings 38 years of experience in aviation compliance and regulatory operations.

His background includes:

✈ FAA Part 139 compliance
✓ TSA coordination
▤ Federal regulatory operations
◉ Multi-agency coordination
⚙ Standard operating procedure development

That experience is the foundation behind Sentinel Operations Group.

FROM AVIATION TO DENTISTRY

Different Industry.
Transferable Perspective.

Darryl is not bringing aviation procedures into a dental office.

He is bringing decades of experience looking at organizations as connected operating systems — where structure, standards, and sound decisions shape how the whole organization performs.

That perspective now informs his work with independent dental practice owners.
