Thornton FAQs
Where is the Thornton clinic?
At 3212 E 104th Ave, Thornton, CO 80233, on the southeast corner of East 104th Avenue and Steele Street, next to 3 Margaritas and Black Jack Pizza.
Do I need an appointment?
No. Walk in to any clinic, or reserve a time online if you'd rather not wait. Telehealth visits are booked online.
What are your hours?
Every clinic is open until 11 PM, every day of the year, including weekends and holidays. Denver Southeast, Littleton and Thornton open at 8 AM daily. Denver Highlands is open 5 PM to 11 PM on weekdays and 8 AM to 11 PM on weekends. Telehealth runs 8 AM to 11 PM daily. See each clinic's hours and address.
Do you take my insurance?
We bill your insurance. We have contracts with all major commercial and government plans, including Medicare and Colorado Medicaid. We can't guarantee we're in network for every commercial plan, because insurers sometimes build narrow networks without telling us.
At the visit we collect your copay and file the claim, then bill any remainder after your insurer processes it. If your plan treats us as out of network or denies the claim, we reduce what you owe to our self-pay rate. Cost and insurance details.
How much does a visit cost without insurance?
Our self-pay prices are posted before you're seen, and an in-clinic visit has a firm maximum however complex it turns out to be. Telehealth visits, physicals and many tests have their own flat fees, and you can split a visit into two payments. See current self-pay prices.
Do you see children?
Yes. Patients of all ages are welcome, and we do sports and school physicals for kids.
Do you have Spanish-speaking staff?
Yes. Se habla español: almost all of our staff speak Spanish, and our online check-in has an Español option.
When should I go to the ER instead?
Call 911 or go to the nearest emergency room for chest pain or pressure, trouble breathing, signs of a stroke (a drooping face, arm weakness or slurred speech), severe bleeding, a serious head injury, a major broken bone, or anything you believe is life-threatening. If you come to us and need a hospital, we'll tell you plainly and help you get there.
