Physician Expertise at the Intersection of Health, Function, and Work

A medical diagnosis does not necessarily establish how a condition affects an individual's ability to work or perform required duties.

Occupational and Environmental Medicine is the medical specialty that examines the relationship between health, functional capacity, and occupational demands. This perspective helps distinguish medical diagnoses from functional limitations and supports objective assessments of work capacity, accommodation needs, and fitness for duty.  These principles also inform retrospective evaluations of military medical and fitness determinations.

A meaningful occupational medical evaluation may require an understanding of:

• The nature and severity of the medical condition;
• Treatment and response to treatment;
• Physical, cognitive, or psychological limitations;
• Prognosis and expected duration;
• Essential job duties;
• Workplace exposures or environmental demands;
• Attendance, endurance, and reliability;
• Safety-sensitive responsibilities; and
• Whether medical limitations are compatible with continued work or service.

This framework is especially useful in disability matters because the most important question is often not simply what condition a person has, but what that condition means functionally.

Our independent medical opinions draw on the four complementary areas of Dr. David's professional training and experience, outlined below.

Every medical opinion begins with the specific question that needs to be answered.

Our evaluations are based on physician review of relevant medical records, clinical history, functional evidence, and applicable medical literature when appropriate. We focus on identifying what the available medical evidence establishes, what remains uncertain, and whether a clinically defensible conclusion can be reached.

Our role is to provide independent medical analysis—not legal representation, claims advocacy, or eligibility determinations. We do not act as attorneys, disability representatives, or claims adjudicators. Final administrative and legal decisions remain with the appropriate employer, agency, board, or adjudicating authority.
