How Public Health Is Organized in Wyoming

Wyoming is the least populous state in the country, with roughly 580,000 residents spread across about 98,000 square miles. That mix of open space and small towns shapes how health departments work here. Our directory covers offices from the capital in the southeast to Lovell in the Big Horn Basin.

At the top sits the Wyoming Department of Health, headquartered at 2300 Capitol Avenue in Cheyenne. Its Public Health Division oversees immunization, infectious disease reporting, maternal and child health, and the state Public Health Laboratory. The legal framework lives mainly in Title 35 of the Wyoming Statutes, which covers public health and safety.

Wyoming leans on a state-and-county partnership. In many counties, the local office is a Public Health Nursing office that delivers state programs close to home. A few communities run their own departments instead. Casper and Natrona County, for example, operate the joint Casper-Natrona County Health Department, and its details appear on the Natrona County page.

The practical result is simple. Your county seat usually has the office you want. The staff there can tell you which services they offer, which ones require a trip elsewhere, and which belong to another agency entirely.

Cheyenne, Casper, and Laramie: The Larger Local Offices

Cheyenne is the state capital and the largest city in Wyoming, so it holds two very different kinds of office. The Cheyenne Health Department at 6101 Yellowstone Road (307-777-7115) is the local office for city and county residents. The Wyoming Department of Health at 2300 Capitol Avenue (307-777-7656) is the state agency. It handles statewide programs rather than neighborhood clinic visits. If you need a birth or death record, start with the state number and ask for Vital Statistics Services. The Laramie County page shows every listing in the county.

Casper is the second-largest city in the state. The Casper-Natrona County Health Department at 475 South Spruce Street (307-235-9340) serves the whole county and is run at the city-county level rather than through the state nursing network alone. Residents of Casper, Mills, Evansville, and the surrounding area start here.

In Laramie, the Laramie Health Department at 2020 Grand Avenue (307-742-6859) serves Albany County, home to the University of Wyoming. Students have campus health services. Families, workers, and retirees in town can ask the county office about community immunization clinics and family health programs.

Rural Wyoming: Small Offices and Long Drives

Outside the larger cities, offices are small and territories are big. Counties often split services between two towns so that fewer people face a long winter drive. Check which office is closer before you leave home. These counties have more than one listing:

Names in public records are not always consistent, so confirm the services at any office by phone before you drive.

Several counties have one main office. Sheridan County Public Health is at 297 South Main Street in Sheridan (307-672-5169). Johnson County Public Health and the Buffalo Health Department share one address, 85 Klondike Drive in Buffalo, and one number, 307-684-2564. Other single offices serve Converse County in Douglas, Campbell County in Gillette, Teton County in Jackson, Sublette County in Pinedale, Weston County in Newcastle, Niobrara County in Lusk, and Sweetwater County in Green River.

Fremont County, centered on Riverton and Lander, has an added layer: the Wind River Reservation, home to the Eastern Shoshone and Northern Arapaho tribes. The Riverton Health Department is at 324 East Washington Avenue (307-856-6454). Tribal members may also receive care through Indian Health Service facilities, so ask both systems what is available.

What a Wyoming Public Health Office Can Do for You

Services vary by county, but most offices cover a similar core. Expect childhood and adult immunizations. The federal Vaccines for Children program covers eligible kids who are uninsured, underinsured, on Medicaid, or American Indian or Alaska Native. Many offices also connect families to WIC, the nutrition program for pregnant and postpartum women, infants, and children under five. WIC eligibility is tied to income, generally up to 185 percent of the federal poverty level, and enrollment in Medicaid or SNAP can also help you qualify.

Other common services include family planning, testing and treatment for sexually transmitted infections, tuberculosis follow-up, home visits for new parents, and emergency preparedness planning. When a disease such as measles or a foodborne outbreak is reported, the county office investigates and works with the state.

Fees depend on the service and the office. Several programs use sliding fee scales based on income, and some adult vaccines carry a charge. Ask for the price when you call, and ask whether the office bills insurance.

What to bring to your visit

Bring a photo ID, your insurance or Medicaid card, and any immunization records. If you are applying for WIC or a reduced fee, add proof of income and proof of address. For a child, bring the parent or guardian's ID as well.

Restaurants, septic systems, and other environmental questions

Many people assume the county health office inspects restaurants. In Wyoming, food and lodging inspections are generally handled by the Consumer Health Services program at the Wyoming Department of Agriculture. Septic systems and drinking water fall under the Department of Environmental Quality and local permitting offices. If you think a meal made you sick, report it to your county public health office first, because nurses there track illness clusters.

Planning around distance and weather

Wyoming winters close roads. Wind and snow regularly shut sections of Interstate 80 between Laramie and Rawlins, and mountain passes can slow trips in the western and northern parts of the state. Check the WYDOT 511 road report before you leave, and call the office to confirm clinic days and hours. Small offices often hold immunization or WIC appointments on set days rather than every day.

Health department offices are not emergency rooms. For an emergency, call 911. For poison questions, call the national Poison Help line at 1-800-222-1222. For a mental health crisis, call or text 988.

The health department network in Wyoming consists of the state health agency and a system of county and city health departments that together deliver public health programs, disease surveillance, and preventive services to residents statewide.

Health Departments locations are available in 30 cities across Wyoming. They are spread across 23 counties.

Cities with the highest concentration include Cheyenne, Buffalo, Laramie, which operate full-service health departments providing comprehensive clinical and environmental health services to large urban populations.

Residents of Wyoming can access their local health department for vaccinations, vital records, food inspection reports, and communicable disease information. Many services are available by appointment, and some are walk-in friendly.

Finding the Right Wyoming Health Office Before You Drive

With 23 counties and long gaps between towns, a two-minute phone call can save hours on the road. Start with the county where you live, not the nearest town, because eligibility rules and clinic schedules are often set locally.

Keep a short checklist. Write down the office name and phone number. Ask which days it offers the service you need. Confirm whether you need an appointment, what to bring, and what the visit will cost. If the office cannot help, ask where to go next. Staff in small Wyoming towns usually know.

Johnson County shows why the call matters. The Buffalo Health Department and Johnson County Public Health share one address, 85 Klondike Drive, and one phone line, 307-684-2564. Directory listings sometimes repeat for that reason, so one building may appear twice.

Teton County Public Health on East Pearl Avenue in Jackson serves a county where most of the land is national park and forest. Sublette County Public Health in Pinedale, Weston County Public Health in Newcastle, and Niobrara County Public Health in Lusk each serve wide, thinly populated areas where one office may be the main public health contact for a large area.

New to the state? Bring your out-of-state immunization records. Staff can often review them and tell you what is missing, which helps with school enrollment and new-job requirements.

The Wyoming Department of Health is the state agency responsible for public health, and its Public Health Division is based in Cheyenne at 2300 Capitol Avenue. Most counties are served by a Public Health Nursing office that delivers state programs locally, while a few communities, including Casper and Natrona County, operate their own local departments. County officials still influence hours and local priorities. The governing statutes are collected in Title 35 of the Wyoming Statutes. For a specific question, call the office in your county seat first. Staff can tell you whether your request belongs to the county, the state, or another agency such as Agriculture or Environmental Quality.

Wyoming's official birth and death records are kept by Vital Statistics Services, which is part of the Wyoming Department of Health in Cheyenne. Call the Department of Health at 307-777-7656 and ask to be connected, because application methods, fees, and processing times can change. Expect to prove your identity and, for records that are not your own, your relationship to the person named. Do not assume your local county health office can issue the certificate on the spot. A quick call to the office in Buffalo, Riverton, Sheridan, or wherever you live will tell you whether they handle the request or send you to the state.

In most counties, yes. Public health offices commonly give routine childhood immunizations and many adult vaccines. The federal Vaccines for Children program covers eligible kids who are on Medicaid, uninsured, underinsured, or American Indian or Alaska Native. Adult vaccines may carry a fee, and supply can vary by season and by office. Bring your immunization record, insurance card, and a photo ID. A parent or guardian should come with the child. Call ahead, because small offices often schedule vaccine clinics on certain days and may not keep every vaccine in stock at all times.

WIC is run through the Wyoming Department of Health and delivered locally, so the first step is calling the office nearest you for an appointment. Pregnant, postpartum, and breastfeeding women, infants, and children under five can qualify. Income generally must be at or below 185 percent of the federal poverty level, and people who receive Medicaid or SNAP may meet that test automatically. Bring photo ID, proof of address, proof of income or program enrollment, and your child's medical or immunization information. A staff member will also do a brief nutrition screening. Ask which town in your county holds WIC appointments, since schedules differ by location.

Restaurant and lodging inspections are generally handled by Consumer Health Services, part of the Wyoming Department of Agriculture, rather than by county health offices. If you suspect a restaurant broke safety rules, contact that program or ask your county office to point you there. If you or family members became ill after eating out, also report it to your county public health office. Nurses there track illness patterns and can start an investigation with the state. Keep any leftover food, note the date and time you ate, and write down your symptoms. For drinking water or septic questions, start with the Department of Environmental Quality and local permitting offices.

First check whether your county has a second office. Lincoln County has offices in Afton and Kemmerer, Park County has Cody and Powell, and Big Horn County has Lovell and Greybull. Many questions, including WIC scheduling and records requests, can start by phone. Check the Wyoming 511 road report before driving, especially on Interstate 80 and mountain routes. In Fremont County, residents of the Wind River Reservation may also use Indian Health Service facilities, which operate separately from the county office. If a storm closes the road, call the office, because staff can often reschedule your visit.
