COVID-19: Are you ready for the next normal?


Dr. Cheung OEM-Advisor is now Cogency

The entire team at Dr. Cheung-OEM Advisor LLC is pleased to announce that we have changed our name to Cogency. The transition will be marked by a significant expansion of our business offerings, which now includes additional environmental services beyond traditional OEM matters.

Cogency TEAM (Toxicological, Environmental and Medical Solutions) will continue to provide the same high quality leadership and advisory services in issues involving occupational hazards and environmental injuries as before. However, we are expanding services to a host of other areas such as building science investigations, indoor air quality surveys, Legionella and other disease cluster investigations, chemical and hazards analyses, remediation scope development and crisis response management.

Our esteemed management team will remain unchanged through this development, although we are equally excited to announce the acquisition of additional staff and consultants who will lend additional resources and capabilities to our clients. The name you see on our invoices and emails will soon change.  However, we will continue to be reachable at our original addresses for the foreseeable future.

Our new logo, reflecting the integration of Toxicological, Environmental and Medical Solutions and name change to Cogency will better reflect our new mission statement:

“Protecting your people, your purpose, and your reputation.”

We look forward to continuing to serve you under our new brand! Please visit our new website at to learn more about our expanded solutions. We will use our new website and social media pages in order to better extend our professional resources and insight to our professional network. Thank you, and we look forward to supporting you in the future.
