HIV Care in Port St. Lucie
Expert HIV Treatment Close to Home
Living with HIV today looks very different than it did even a decade ago. With the right care and treatment, people with HIV can live long, healthy lives — and achieving an undetectable viral load protects both your health and the health of your partners.
At Midway Specialty Care Center in Port St. Lucie, our infectious disease physicians bring focused expertise to HIV management. Unlike a general practitioner, our providers work exclusively in infectious disease — which means your HIV care is built on deep, current clinical knowledge, not divided attention.
Whether you were recently diagnosed, transferring care, or returning to treatment after time away, we're ready to build a plan that fits your life.
What HIV Care at Midway Includes
Your care is comprehensive, coordinated, and built around your goals.
Antiretroviral Therapy (ART)
ART is the cornerstone of HIV treatment. Your provider will select a regimen based on your viral strain, tolerance, and lifestyle — with the goal of reaching and maintaining an undetectable viral load. We stay current with the latest FDA-approved treatments, including long-acting injectable options that eliminate the need for daily pills.
Viral Load & CD4 Monitoring
Regular lab work is essential to evaluating how well your treatment is working. We monitor your viral load (the amount of HIV in your blood) and CD4 count (a measure of your immune strength) on a schedule tailored to where you are in treatment. Early detection of changes means faster adjustments — keeping your health on track.
Medication Management & 340B Access
Antiretroviral medications can be expensive, but our participation in the federal 340B Drug Pricing Program allows us to provide HIV medications at significantly reduced costs. Our care team also works with pharmaceutical assistance programs and insurance plans — so cost is never a reason to skip treatment.
Resistance Testing
HIV can develop resistance to certain antiretroviral medications over time. Resistance testing helps identify which drugs will be most effective for your specific strain, allowing your provider to select or adjust your regimen before resistance becomes a barrier to an undetectable viral load.
Case Management & Social Support
Medical care is only one piece of the puzzle. Our case managers connect patients with insurance enrollment assistance, Ryan White Program support, housing resources, transportation, mental health referrals, and community services. We understand that life circumstances affect health — and we work to remove barriers to care.

Lauren Leeflang
PA-C
Lauren Leeflang is a Board Certified Physician Assistant. Lauren was only two semesters away from graduating with a Bachelor of the Arts in Anthropology from the University of Florida when she enrolled in a Medical Anthropology course. From that moment on, she was fascinated by the societal and cultural influences on healthcare and medicine, leading her to immediately enroll in Florida Atlantic University's Pre-Health Professions Post-Baccalaureate program upon the completion of her degree. It was there that she learned more about the Physician Assistant profession and the nationwide shortage of primary care providers. She graduated with honors from the Nova Southeastern University Physician Assistant Program in Orlando, Florida, where she earned her Masters of Medical Sciences. As a PA, Lauren is passionate about primary care, and appreciates the diverse clinical challenges of HIV and other infectious diseases. A self-described "food nerd," Lauren spends much of her free time in the kitchen trying new recipes, or brewing beer with her husband. She also loves gardening, the beach, and her adorable dog, Kona.

Who We Help
Our Port St. Lucie clinic welcomes patients at every stage of their HIV journey.
Newly Diagnosed
A positive diagnosis can feel overwhelming. Our team will walk you through exactly what your diagnosis means, what treatment involves, and what to expect — with honesty, compassion, and no judgment.
Transferring Care
Moving your HIV care to a new provider doesn't need to be complicated. We make it easy to transfer records, continue your current regimen, or explore new treatment options if you're ready for a change.
Returning to Care
Life happens. If you've been out of care — for any reason — we won't ask for explanations. We'll simply meet you where you are and work with you to get back on track safely and without pressure.
Long-Term Management
For patients already thriving on ART, we provide consistent long-term monitoring, medication reviews, and proactive management of HIV-related health considerations as you age.
What to Expect at Your First Visit
Getting started is straightforward. Here's how your care begins.
Schedule Your Appointment
Call our Port St. Lucie office at (772) 335-4234 or submit the request form. Our staff will help identify the right appointment type, answer any intake questions, and let you know what to bring.
Medical History & Baseline Labs
Your provider will conduct a thorough medical history review and order baseline laboratory tests — including HIV viral load, CD4 count, resistance testing if needed, and a full metabolic panel. These results form the foundation of your individualized treatment plan.
Your Treatment Plan
Once labs are reviewed, your provider will discuss your treatment options in plain language. Together, you'll decide on an ART regimen that balances effectiveness, side effect profile, and your daily routine. If you're already on ART, we'll evaluate whether your current regimen is optimal.
Ongoing Monitoring & Follow-up
HIV care is a long-term relationship. Follow-up appointments are typically scheduled every 3–6 months, with labs reviewed at each visit to confirm your viral load remains undetectable. Your care team is reachable between visits for questions, prescription refills, and concerns.
