A new pop-up clinic in McKinney is helping meet needs for thousands in the city who are under-insured and uninsured.

Hope Clinic opened its doors in July. The clinic offers free health care for people who qualify.

Since then, founder Caitlin Twyman says doctors have treated 75 patients.

"There's this huge gap of people that just don't have access to something as simple as medical care," Twyman said.

The clinic is only open on Mondays.

Each week, a team of volunteers transforms donated office space into exam rooms.

"Maybe we can't meet all 25,000 uninsured in our city, but for the people who we've already started and we've already seen, it matters to them and to us that's enough," Twyman said.

Twyman says the clinic has been so busy they need more volunteers, particularly medical professionals.
