As Infectious Disease Specialists we manage patients with complex infectious diseases and requiring rigorous antimicrobial therapy.

We see hospitalized patients primarily at Methodist Hospital and occasionally at other area hospitals.

We also see patients in our offices in the Methodist Professional Building, located just east of Methodist Hospital.

Patients are seen by referral from other physicians and healthcare providers. Patients are referred to us from Nebraska, western Iowa, northwestern Missouri, and South Dakota.

The specialty of infectious diseases, often referred to as ID, covers a broad array of disease.

ID patients have been infected by a bacteria, virus or other microorganism. ID patients are often challenging even for the ID Specialist. Microorganisms are constantly evolving in complexity. Antimicrobial medicines become more specialized. With the emergence of antibiotic resistant bacteria, the challenges are greater than ever.

Many infections can be treated by the primary care physician. However, some patients may be so ill or have a disease so baffling that the primary care physician refers the patient to the ID Specialist. Knowing what disease a patient may have and which antimicrobial therapy to use is a skill developed with years of experience.

Patients referred to Dr. Penn usually fall into one of two categories:

Complex Antimicrobial Treatment - In the first, the patient's disease is known and yet has become so severe or has so failed to respond to standard treatment, as to require a unique regimen of antimicrobial medicines for treatment. An ID Specialist experienced with various diseases and treatments is able to draw on that experience and order the needed antimicrobial treatment.

Difficult Diagnosis - In the second category, the patient's disease is unknown, and Dr. Penn must determine what it is before determining the appropriate treatment for it. Dr. Penn is uniquely skilled at making the difficult diagnosis. Over the years has developed a reputation for these skills.
