Team & Careers

Senior-led geoscience practice rooted in BC terrain.

Third Rock Geoscience is a small, field-driven team providing terrain stability and karst expertise to forestry and resource operations across British Columbia.

Our work is technical, practical, and grounded in real-world decision-making. We operate in steep coastal terrain, remote access environments, and complex limestone systems where judgment matters.

This is not high-volume consulting. It is focused, accountable geoscience.

Our Team

Patrick Haesevoets, P.Geo.

Founder & Professional Geoscientist

Patrick leads terrain stability and geohazard work across Vancouver Island, coastal BC, and the Interior.

His focus is site-specific terrain stability assessment for forestry operations, including:

Hazard classification
Landslide initiation potential
Construction method guidance
Rainfall shutdown recommendations

All deliverables are reviewed prior to release. Field calls align with final reports. Consistency is a defining standard of the practice.

Patrick’s background includes extensive experience in steep coastal terrain and helicopter-access environments. His role combines field investigation, regulatory accountability, and operationally practical decision-making.

Melissa leads karst assessments and contributes to terrain stability and sediment risk evaluations.

Her experience includes:

Advanced karst training in Canada and the United States
Contribution to internal karst management guidance for major forestry operators
Specialized expertise in groundwater vulnerability and sediment pathway assessment
Over 14 years of terrain and landslide risk experience

Her work bridges industry and sensitive karst environments with technical rigor and discretion.

Dave Bergman

Interior Terrain Support

Based in the BC Interior, Dave supports terrain and geohazard assessments in inland environments, expanding the firm’s geographic footprint beyond the coast.

How We Work

We operate as a senior-led team. That means:

Field assessments are conducted or directly overseen by experienced professionals.
Recommendations do not shift between summary and final report.
Documentation is defensible and aligned with regulatory expectations.
Operational realities are factored into recommendations.

We value clear communication, direct feedback, and practical solutions.
