Clinical Role and Leadership

Dr. Hawley-Molloy practices infectious diseases medicine in Santa Fe at CHRISTUS St Vincent Regional Medical Center’s Adult & Family Care Clinic. As a subspecialist, he evaluates and manages infections that are complex, resistant to treatment, or difficult to diagnose. His military career included serving as Deputy Chief of the Infectious Diseases Service at Tripler Army Medical Center in Hawaii, Director of Medical Services at Landstuhl Regional Medical Center in Germany, and leading the Internal Medicine Residency at Brooke Army Medical Center in San Antonio, the Department of Defense's largest graduate medical education program, training approximately 90 physicians across the Army and Air Force. That leadership experience shaped not only how he thinks about complex cases, but how he teaches others to do the same.

He provides specialized care for conditions such as:

• HIV infection prevention, evaluation, treatment, and long-term management
• Hepatitis C and other chronic viral infections
• Osteomyelitis and deep bone infections
• Drug-resistant bacterial infections, including MRSA
• Tropical and travel-related infections
• Tuberculosis and mycobacterial infections
• Complex infections requiring prolonged or specialized antibiotic therapy
• Post-surgical and hospital-acquired infections
• Immunization counseling and infection prevention

What You Can Expect from Care with Dr. Hawley-Molloy

Patients describe Dr. Hawley-Molloy as thorough, kind, and direct, someone who puts you at ease while taking the time to explain what he's finding and why it matters. One patient noted that his approach made even a stressful situation feel manageable: no question was too small, and no concern was dismissed. That style reflects decades of practice in high-stakes clinical environments, from Army hospitals to academic training programs, where clarity and calm are non-negotiable.

You can expect:

• A thorough review of your infection history, labs, imaging, and prior treatments before any new recommendation
• Clear, plain-language explanations of your diagnosis and why a specific treatment plan is being recommended
• A provider who listens carefully and welcomes every question, no matter how basic it may seem
• Coordination with your other physicians and specialists to ensure your infection treatment fits within your broader care plan
• Follow-up to track your response to treatment and adjust the approach if needed

Diagnostic Approach

Infectious diseases is a consultative specialty. Dr. Hawley-Molloy is typically called in when an infection is unusual, persistent, or resistant to first-line therapies. His evaluation process includes a detailed review of culture results, lab work, and imaging, combined with a clinical history that accounts for travel, exposures, medical history, and immune status. His training in tropical medicine, including completion of the military's Tropical Medicine Course, gives him a diagnostic lens that extends beyond infections commonly seen in the United States. 

Research, Clinical Insight, and Thought Leadership

Dr. Hawley-Molloy is the author or co-author of over 25 peer-reviewed articles and book chapters. His research has focused on areas with direct clinical impact, such as the behavior and treatment of drug-resistant bacteria such as Acinetobacter and MRSA in military and community settings, the efficacy of antifungal and antimicrobial agents against tropical infections like leptospirosis, and innovations in medical education. His work on colistin resistance and antibiotic susceptibility in organisms isolated from deployed service members has contributed to the broader understanding of how resistant infections spread in high-risk environments. He has also published on leadership training in graduate medical education and on modernizing how physicians learn from clinical literature. This research background means that the treatment decisions Dr. Hawley-Molloy makes in Santa Fe are grounded in the same evidence base he has helped build.
