Common Questions
Q: How does medical weight loss work? At your first visit, one of our nurse practitioners reviews your health history, current medications, and personal goals. From there, we create a customized plan that may include GLP-1 medications, nutrition counseling, vitamin therapy, and regular check-ins to keep you on track.
Q: What are GLP-1 medications like semaglutide and tirzepatide? GLP-1s are FDA-recognized prescription medications that help regulate appetite and blood sugar. They work by mimicking a natural hormone in your body, helping you feel full longer and reducing cravings. Our nurse practitioners determine the right medication and dosage for your body.
Q: Do I need to be a certain weight to qualify? We treat patients regardless of BMI in our weight management program. Not sure if you qualify? Schedule a consultation and we'll walk you through it — no pressure, no judgment.
Q: Does insurance cover your services? Some insurance plans may cover weight loss medications, and we can submit claims on your behalf. Office visits are self-pay: $125 for your initial consultation and $75 for follow-ups.
Q: Do you offer virtual visits? Yes! We offer TeleHealth appointments for both weight management follow-ups and acute illness visits. It's healthcare on your schedule.
