About Us

The BioServices team is composed of biologists and ecologists with extensive backgrounds in research and environmental consulting. This marriage of skills allows for an in-depth understanding of your project’s needs as they relate to both the regulatory and environmental settings.

With more than 200 years of combined experience, the San Diego Natural History Museum is a leader in the natural sciences and a renowned center for the scientific study of natural history, biological diversity, and evolution within our region. Our staff contribute to conservation through scientific research, monitoring, and public outreach and education.

He is a contributing author to the San Diego County Mammal Atlas and sole author of the 22 bat species accounts therein.

Brenna Ogg, Senior Biologist / Business Development

With more than 14 years of local experience in field biology and environmental consulting, and is a County of San Diego approved CEQA consultant for biological resources. She manages and conducts general biological assessments and impact analyses, environmental compliance monitoring, vegetation mapping, habitat restoration, mitigation implementation and monitoring, and focused surveys for sensitive species in central and southern California, and southwestern Arizona. She maintains federal and state permits to conduct protocol surveys for Quino Checkerspot Butterfly, listed vernal pool branchiopods (e.g., fairy shrimp), and California Gnatcatcher.

Curators, scientists, and associates in the museum’s research departments also regularly serve as extensions of our BioServices staff, giving you direct access to the specialists who “wrote the book” on the plants, birds, and mammals of our region.
