Serving LoHi & Surrounding Denver Areas
Tucked along Tejon Street in the heart of Lower Highlands, our flagship Onus IV lounge is a short walk from the shops and patios of 32nd Avenue and just minutes from Highland Square, Jefferson Park, and Sunnyside. Clients from Berkeley, Sunnyside, and downtown Denver stop in before a walk along the South Platte River or a morning at Confluence Park, while our proximity to I-25 and Speer Boulevard makes us an easy detour for anyone commuting through central Denver. As Onus IV's original location, LoHi has been home base for over a decade of hydration, recovery, and longevity care from our licensed nurses and paramedics.
