Areas We Serve Across Collin County & North Dallas
One clinic in Allen. Sixteen communities. Care worth the drive.
InfusaLounge Integrative & Functional Medicine serves patients from across Collin County and the northern Dallas suburbs from one clinic at 190 E Stacy Rd #1720 in Allen — just off US-75 at Stacy Road, minutes from the county’s main north-south corridor. Nurse practitioner Triny Nguyen, APRN leads patient care with medical oversight from Dr. Phyllis J. Gee, MD, FACOG, and our care model is built for patients who drive to us: comprehensive first visits, treatment plans that consolidate appointments, and walk-in availability for select services.

What Patients Travel For
Most of our patients could find a vitamin drip closer to home. They drive to Allen for what drip bars don’t offer:
Root-cause functional medicine — physician-supervised programs built on advanced diagnostics, not guesswork
Medical weight loss — including semaglutide and tirzepatide programs with real clinical oversight
Clinical-grade IV therapy — from custom vitamin drips to high-dose NAD+ and specialty infusions beyond standard hydration menus
Hyperbaric oxygen therapy — hard-shell chamber treatment few clinics in the region offer
Chelation therapy and heavy metal testing for patients with confirmed toxic burden
PRP and exosome therapy for joint and soft-tissue regeneration
Ozone therapy, red light therapy, and peptide therapy integrated into supervised care plans
Our Home: Allen, TX
Allen isn’t just one of the communities we serve — it’s home. InfusaLounge has practiced root-cause and integrative medicine on Stacy Road since 2018, and in that time more Allen residents have chosen us than patients from any other city — thousands of Allen neighbors over our eight years. If you live here, the most comprehensive functional medicine, IV therapy, and regenerative care in Collin County isn’t a drive across town; it’s a few minutes down the road.
We care for patients from across Allen — Twin Creeks, Star Creek, Watters Creek and Montgomery Farm, and the neighborhoods along Stacy, Ridgeview, and Alma — most just five to ten minutes from our door in The Village at Allen. Because we’ve been part of this community for years, your care is built on relationships, not a revolving door.
Whatever brought you here — fatigue, hormones, gut issues, weight, recovery, or simply wanting to feel like yourself again — you can start close to home, with a physician-led team that already knows Allen.
Visiting InfusaLounge
We’re at 190 E Stacy Rd #1720, Allen, TX 75002, on the south side of Stacy Road just east of US-75 — take the Stacy Road exit and you’re here in under a minute, with free parking at the door. Weekend hours (9 AM–3 PM Saturday and Sunday) make us reachable for patients whose weekdays don’t allow a 20-minute drive.
First visits for functional medicine start with a consultation; IV therapy, B12 shots, and NovaPod sessions accommodate walk-ins during business hours. And if you’re not sure whether a therapy fits your situation, ask — our clinical team reviews every new patient’s plan.
