Outstanding experience at Onus IV! From the moment I walked in, the customer service was top-tier. Store manager Claire is absolutely fantastic—professional, attentive, and genuinely caring. Hope is extremely friendly and makes you feel comfortable right away. The staff were just as amazing, making everything smooth, comfortable, and stress-free. You can really tell they care about their clients, not just the service. Clean space, great vibes, and people who know what they’re doing. Highly recommend; this place understood the assignment 👏💧

Been coming to Boulder for a while now for injections (MICC D & B12)…highly recommend. Onus has been a huge part of the success on my health journey. Claire is awesome and so encouraging! I also bring my flatlander family here for IVs the second they land to avoid altitude sickness…I’ve enjoyed some IVs as well when under the weather. Go see them and Treat Yo Self!

This place is great. We come here every time we visit Boulder. Every staff member has always been friendly and helpful. You inform them of your concerns and they tell you what’s the best game plan. Definitely 5 stars! My husband and I will be coming to see you all tomorrow.
