Manassas Walk In Clinic That Actually Gets It

Healthcare shouldn't feel like solving a puzzle. You need medical care that fits your real life, not perfect scheduling that never works out. Our walk in clinic in Manassas understands that medical problems don't follow business hours, and neither should quality healthcare.

Located right here at 8551 Rixlew Lane Suite #140 A in Manassas, we've been the go-to walk in clinic for families throughout Prince William County. Whether you live near Manassas Mall or over by Battlefield High School, we're the medical clinic that treats you like a neighbor, not just another appointment slot.

Dr. Jerry K Lee and our board-certified team know that good healthcare starts with actually listening to patients.

Walking into our medical clinic feels different - we remember your name, your concerns, and we understand that sometimes you just need someone to help you figure out what's going on with your health.

Same-Day Care When You Need It Most

Our walk in clinic handles those health situations that can't wait for a regular appointment. From minor injuries that happen during weekend soccer games to sudden illnesses that pop up on Monday morning, we're equipped to help families get back to their normal routines quickly. Learn more about our urgent care services in Manassas.

Remember when getting medical care meant choosing between waiting days for an appointment or spending hours in an emergency room? Our walk in clinic eliminates that frustrating choice. We provide same-day medical care for non-emergency situations that still need professional attention.

A local teacher told us our walk in clinic saved her vacation plans when she developed a respiratory infection the day before leaving town. Instead of canceling her trip or visiting an expensive emergency room, she walked in, got treated, and was feeling better within 24 hours.

Comprehensive Weight Loss Services That Work

Losing weight feels impossible when you're trying to figure it out alone. Our medical weight loss service takes a completely different approach - we look at your whole health picture, not just hand you a generic diet plan that doesn't fit your real life.

Sarah from the Sudley area lost 45 pounds through our physician-supervised weight loss program last year. She said the difference was having medical supervision and B-12 injections to support her energy levels, plus realistic nutrition counseling that worked with her busy schedule as a working mom. Discover our medical weight loss programs and see if they're right for you.

Our weight loss service includes regular medical monitoring, metabolism assessment, prescription support when appropriate, and honest conversations about what's actually realistic for your lifestyle. We've helped teachers, construction workers, busy parents, and retirees all find sustainable approaches to better health.

Workplace Wellness Programs That Actually Help

Our wellness program isn't about impossible fitness routines or perfect meal plans. It's about making small, sustainable changes that add up to better health over time. We've seen too many people get discouraged by extreme programs that promise quick fixes but don't work long-term.

The wellness program includes regular health screenings, vaccination updates, lifestyle counseling, and chronic disease management. We work with you to spot potential health risks before they become bigger, more expensive problems.

A local office manager credits our wellness program with helping her avoid the diabetes diagnosis that runs in her family. Through gradual changes to her eating habits and activity level, her blood sugar levels have stayed in the healthy range for over two years.

Your Family's General Practitioner and Primary Care Provider

Finding a good general practitioner shouldn't be this complicated, but here we are. Our approach combines traditional family medicine values with modern healthcare tools. We get to know you and your family's health patterns, not just your current symptoms.

Dr. Jerry K Lee has been providing primary care in the Manassas area for years. He believes that good family medicine means building relationships and understanding each person's unique health situation, not just treating isolated problems.

As your general practitioner, we handle routine checkups, manage chronic conditions like diabetes and high blood pressure, coordinate referrals to specialists when needed, and serve as your central healthcare resource. We explain things in plain English and involve you in decisions about your care. Schedule an appointment for primary care services.
