The bump on his forehead would not go away, and his circulation problems were getting worse, but Gregorio Segura could not afford to see a doctor.

That was, until the uninsured 50-year-old musician heard about the expanded medical services being offered at the Arlandria Health Center in Virginia.

"This has been my salvation," Segura said as he waited to see the doctor at the clinic one night last month. It was the Alexandria resident's fourth visit since January.

"If they did not exist, I could not take care of these problems," he said.

Thanks to a new federal grant, the clinic's staff is hoping to reach more people like Segura. The health center, established in 1993, traditionally served only low-income women and children in Alexandria. The three-year, $1.85 million grant, awarded last year, means the clinic can now provide medical services to anyone who walks through the door, regardless of income, gender or where they live.

"We're breaking new ground in a number of ways," said Jennell Charles, executive director of Alexandria Neighborhood Health Services Inc., the nonprofit organization that oversees the center. "This center is one of the few of its kind in the country and the first in Northern Virginia."

The clinic expanded its services seven months ago, and word has been spreading throughout the Washington area. Chereka Elam, 23, of Oxon Hill learned about the Alexandria clinic from a friend after she found out she could no longer afford her Kaiser health plan.

"She told me about this facility that takes anybody," said Elam, a hairstylist.

Elam drove five miles to the clinic to get a checkup. The cost: $10.

"This is better for me," she said. "I pay as I come, and I can afford it."

In Prince George's, the centers run by Greater Baden Medical Services also serve people from across the region.

At the Arlandria health center, patients of all races, income levels and geographic areas trickle in, but most of the clinic's clients continue to be Latino immigrants, Charles said.

With surging health care costs and more people without insurance, the need for accessible and quality health care is not just an issue for the poor, Charles said.

"This is not poor care for poor people," she said. "It's good care for people who need health care no matter what their income, residency, race or status is."

Nationally, about 15 million people use these types of centers, and about 6 million of them are uninsured, according to the National Association of Community Health Centers. But Dan Hawkins, the association's policy director, said there are millions more who don't have access to the kinds of services these clinics provide -- even those who have insurance.

"We just released a study that shows 36 million Americans do not have a regular family doctor or a regular source of primary care," Hawkins said, adding that half of those cited have health insurance. "There is just no place for them to get the care they need."

Rick Shinn, director of public affairs for the Virginia Primary Care Association, said the centers offer various services, based on community need, including medical, dental, preventive, behavioral and pharmaceutical services.

The 17-member staff at the Arlandria Health Center includes a medical director, two family nurse practitioners, two registered nurses, three nursing assistants and a part-time pediatrician. Clients pay for services on a sliding scale based on income, Charles said.

The clinic is at the Presidential Gardens Apartments, where a majority of residents are black and Latino, she said.

As part of the federal grant requirements, 51 percent of the clinic's 17-member board must also use the clinic, so Charles has been recruiting volunteers such as Justiniano Perla and Marlene Bonilla, both of whom have sought medical care at the clinic, to serve on the board and help with community outreach.

In particular, the clinic wants to reach out to men, who, as a group, tend to not seek medical treatment as often as women.

"We want to encourage men to come in and get medical checkups," said Roger C. Chinery, the center's medical director. In some immigrant cultures, for example, men do not seek care until there is a serious problem, he said. Since the center expanded its services to include men and adjusted its hours to accommodate people after work, Chinery said, he has seen some male patients who have never been to a doctor.

Chinery said many are suffering from illnesses that can result from neglect, such as diabetes and hypertension.

In addition to medical services, the center offers counseling and therapy. The small administrative office has brochures that address myriad mental health issues, from dealing with domestic abuse to building self-esteem.

Hawkins, of the health centers association, said that is the goal in establishing these types of clinics: affordable, accessible, quality health care.

"It's not winning the war, but it's a critically important first step," he said.

"Hopefully, it won't be the last step."

At the Arlandria Health Center, medical director Roger C. Chinery and assistant Claudia Torres treat Gregorio Segura, an uninsured musician from Alexandria. Although the majority of clients are Latino immigrants, people of all races, income levels and geographic areas seek medical care at the clinic. Medical assistant Gulnaz Rahman draws blood from Segura at the center. The clinic's staff includes a medical director, family nurse practitioners, registered nurses, nursing assistants and a part-time pediatrician.
