Infectious Disease Specialists

What Infectious Disease Specialists does

Infectious Disease Specialists of Southeastern WI, SC is a private specialty medical practice founded in 1963 and headquartered at 150 S. Sunny Slope Rd., Suite 136, Brookfield, Wisconsin. The practice delivers diagnosis, treatment, and prevention of infectious diseases including HIV/AIDS, hepatitis (A-G), tuberculosis, influenza, pneumonia, sexually transmitted infections, urinary tract and skin infections, Lyme disease, and West Nile virus. Core clinical services include office consultations, an on-site Antibiotic Infusion Center for IV antibiotic therapy, healthcare epidemiology and infection control for hospital partners, transplant infectious disease support, antimicrobial stewardship oversight, telehealth follow-up visits, and hospital inpatient consultations across the greater Milwaukee area.

The practice is staffed by four board-certified infectious disease physicians (Dr. Thomas A. Taft (retired), Dr. William D. Timm, Dr. David M. Letzer, Dr. Laila Mossa-Basha) and five physician assistants (Kathleen Barta, Peter Collins, Summer Kimble, Sarah Stinski, Lauren Sweeney), supported by a nurse manager, registered nurses, and administrative staff. IDS holds embedded partnerships with Ascension, Aurora, Froedtert Health, and ProHealth Care, providing inpatient coverage, infection control chair positions, and antimicrobial stewardship medical direction across these systems. Dr. Letzer serves as Medical Director of Richard's Place, an HIV/AIDS residential facility, and as Chair of the Wisconsin Medical Society's COVID-19 Task Force.

The business model is professional-services fee-for-service: revenue derives from office visits, infusion therapy, telehealth, and inpatient consultations, with reimbursement through major insurance carriers plus cash, check, and credit card payments. Patient acquisition is referral-driven from primary care physicians and specialists; no direct-to-consumer or marketing-led growth is evidenced. The practice holds HIPAA compliance, BBB accreditation, and documented HIV outcomes of 88.3% undetectable viral load versus a 25% national average. No funding rounds, acquisitions, or institutional investment are evident; the practice operates as a physician-owned partnership under the SC (Service Corporation) legal structure.

Expansion highlights4 records

Direct peers

• Metro Infectious Disease Consultants: One of the largest infectious disease physician group practices in the U.S., operating multiple infusion centers and providing inpatient ID consultations across the Midwest and beyond. Directly comparable to IDS in specialty focus, infusion therapy delivery, and hospital-based ID services, though at significantly larger scale.
• ID Care: New Jersey-based infectious disease specialty physician practice offering HIV, hepatitis, infusion therapy, and travel medicine across multiple office locations. Closely comparable to IDS in scope of services and physician-group operating model.
• Infectious Disease Consultants of Atlanta: Regional ID physician group in Georgia providing infectious disease consultations, infusion therapy, and HIV/hepatitis care to a metropolitan referral base. Comparable to IDS in service mix and physician-led specialty practice model.
• Carolina ID Consultants: Regional infectious disease physician practice serving the Carolinas with similar outpatient consultative and infusion services. Operates as a comparable specialist ID group practice anchored in a single regional market.
• Texas Infectious Disease Consultants: Multi-physician ID specialty group providing hospital and outpatient infectious disease services across the Dallas-Fort Worth metro. Directly comparable in service breadth (HIV, hepatitis, infusion, stewardship) and physician-group operating structure.

Broad incumbents

• UW Health Infectious Disease Division: Academic infectious disease division at the University of Wisconsin providing specialty ID care, stewardship, and transplant ID across the same Southeastern Wisconsin market as IDS. Comparable on service mix but operates within a much larger integrated academic health system.
• Aurora Health Care: Large integrated health system in Eastern Wisconsin that both partners with IDS (for inpatient ID coverage and stewardship) and competes for the same ID patient population. Comparable as a regional incumbent with embedded ID specialty capacity.

Others

• Quest Diagnostics: National clinical laboratory provider that IDS likely uses for diagnostic testing across infectious disease cases. Not a competitor but a key upstream enabler and ecosystem participant in the ID care pathway.
