Laurie is friendly concise and quick to help you get started with your journey with a GLP-1. The staff from the front desk, body scan check in, and usher to the other building are friendly and approachable. I was hesitant about using GLP-1s and their staff was able to reassure my decision while still respecting my thoughts and opinions about taking them. I highly recommend their office for those who are looking to improve their health. Thank you, LIWLI!
