Mark Collins , MD, Infectious Disease Specialist

Dr. Mark Collins is an infectious disease specialist based in Seattle with a clinical focus on diagnosing and treating bacterial infections and managing Antibiotic therapy. He works with adults who have acute infections—such as pneumonia, urinary tract infections, and skin infections—as well as patients with recurrent or more complex conditions that require careful Antibiotic selection and monitoring.

In his daily practice, Dr. Collins reviews each patient’s symptoms, physical examination findings, and test results before recommending treatment. When Antibiotics are appropriate, he explains why a specific drug and dose are chosen, how long therapy should last, and what side effects or warning signs patients should keep in mind. He also coordinates follow-up visits or lab tests when needed to track response to treatment.

Patients appreciate Dr. Collins’ clear, straightforward explanations about when Antibiotics are necessary and when other approaches may be more appropriate. He spends time discussing the difference between viral and bacterial infections, why unnecessary Antibiotic use can be harmful, and how to complete treatment in a way that supports recovery and reduces complications.

By combining precise diagnosis, responsible Antibiotic use, and structured follow-up, Dr. Collins helps patients treat infections effectively while supporting long-term Antibiotic effectiveness for both the individual and the wider community.
