Pulmonary Associates of Fredericksburg is an independent lung, sleep and critical care practice at 521 Park Hill Drive, Fredericksburg, VA 22401, in the medical office park right behind the Emergency Room of Mary Washington Hospital. The office is open Monday through Friday, 8:00 a.m. to 5:00 p.m., and the appointment line is (540) 899-1615. Between noon and 1:00 p.m., calls roll over to an answering service that handles emergencies only.
The group has cared for patients in the Fredericksburg region since 1990. Its physicians are board certified in pulmonary, sleep and critical care medicine, and they also staff the intensive care units at Mary Washington Healthcare hospitals. The practice sees adults aged 17 and older, plus teenagers aged 13 to 16 who need help with sleep apnea or asthma.
What sets it apart is how much happens under one roof: breathing tests, walking oxygen tests, overnight oximetry and an accredited overnight sleep lab are all in the same building. Below you will find the current doctors and nurse practitioners, the full list of services, hours, insurance details and practical tips for your first visit.

A quick note on names. Online directories and insurance lists spell this group several ways, including “Pulmonary Associates of Fredericksburg, Inc.” and “PAF.” Some directories even repeat the city and list it as Pulmonary Associates of Fredericksburg Fredericksburg VA. All of these point to the Park Hill Drive practice. One name to watch out for is “Fredericksburg Pulmonary Associates, P.A.,” which is a different, unrelated group registered in Fredericksburg, Texas. If you are searching for Pulmonary Associates of Fredericksburg Virginia, make sure the address shows Park Hill Drive and a 540 area code.
Location and Office Hours
The practice has one office. Because it sits right behind Mary Washington Hospital, it is easy to combine a clinic visit with hospital imaging, labs or an outpatient procedure on the same trip.

Doctors at Pulmonary Associates of Fredericksburg
The roster below comes from the practice’s own providers page, checked in October 2026. Staff change from time to time, and older directories still list some physicians who no longer appear on the current roster, so confirm your provider when you call.
Physicians
| Physician | Specialties | Training (as listed by the practice) |
|---|---|---|
| Jeffrey Rehm, MD | Internal medicine, pulmonary, critical care, sleep medicine | Medical school at the University of Maryland; internal medicine residency and pulmonary and critical care fellowship at the University of North Carolina |
| Rohit Goyal, MD | Internal medicine, pulmonary, critical care | Medical school at West Virginia School of Medicine; internal medicine residency at Lenox Hospital; critical care fellowship at St. Vincent’s Hospital |
| Ali Hafiz, MD | Internal medicine, pulmonary, critical care | Also listed in the Mary Washington Health Alliance physician directory |
All three physicians are intensivists as well as office pulmonologists. In practical terms, the doctor who manages your COPD or pulmonary fibrosis in the clinic may be the same one caring for you if you are admitted to the ICU at Mary Washington Hospital.
Nurse Practitioners
- Chelsea Koskovich, NP – Lead nurse practitioner and a board-certified Adult-Gerontology Acute Care NP (AGACNP). She has been with the practice since 2017, brings more than 15 years of nursing experience in cardiovascular and intensive care, and is a Daisy Award recipient. She follows patients with a wide range of lung and sleep problems.
- Corinnia Wagner, NP – Board-certified AGACNP-BC, with a master’s in nursing from Simmons University in Boston.
- Ann Marie Russell, FNP – Board-certified Family Nurse Practitioner who joined in November 2021. She grew up in the Fredericksburg area and worked as an ICU and ER nurse before moving into urgent and primary care.
- Debra Adams, FNP – Family Nurse Practitioner.
- Amber French, ACNPC-AG – Adult-gerontology acute care nurse practitioner.
Nurse practitioners often see follow-up visits, inhaler checks and quicker appointments when a physician’s schedule is full. Ask for an NP visit if you need to be seen sooner.
Services at Pulmonary Associates of Fredericksburg
Lung Conditions Diagnosed and Managed
The practice lists the following conditions, among others:
- Airway disease: asthma, COPD and bronchitis
- Symptoms that need a workup: chronic cough and shortness of breath
- Abnormal scans: abnormal chest imaging, lung masses and lung cancer
- Lung tissue disease: interstitial lung disease
- Fluid and infection: pleural effusion and pneumonia
- Lung blood vessels: pulmonary embolism (blood clots) and pulmonary hypertension
- Breathing during sleep: sleep apnea, hypoventilation syndrome, narcolepsy and restless legs syndrome
If you have been told you may have high pressure in the lung arteries, our guides on how pulmonary hypertension is diagnosed and its common causes explain why a lung specialist is often the first stop. Pulmonary hypertension that grows out of COPD or low oxygen is known as Group 3 pulmonary hypertension, and it is managed by treating the lung disease itself.
On-Site Pulmonary Function Lab
The breathing lab is staffed by four board-certified respiratory therapists and one technician. It follows American Thoracic Society testing standards, and every study is read by the practice’s own board-certified pulmonologists. There are three testing rooms, two of them with a body box (plethysmograph) for measuring total lung volume.
StatPearls’ review of pulmonary function tests notes that these tests do not give a diagnosis on their own. They measure how well your lungs move air and pass oxygen into the blood, show how severe a problem is, and track whether treatment is working.
| Test | What it measures | Typical “normal” marker |
|---|---|---|
| Spirometry | How much air you blow out and how fast (FEV1, FVC) | FEV1/FVC above 0.70; FEV1 and FVC above 80% predicted |
| Lung volumes (body box) | Total lung capacity and trapped air | TLC above 80% predicted |
| Diffusion capacity (DLCO) | How well oxygen crosses into the blood | Above 75% predicted |
| Bronchodilator response | Whether airflow improves after an inhaler | A clear rise suggests reversible narrowing, as in asthma |
| Six-minute walk test | Walking distance and oxygen levels on exertion | Compared with your past results and predicted values |
For background on what the lung volume numbers mean, see our guide to pulmonary volumes and capacities. To understand why a low DLCO matters, our article on gas exchange between the alveoli and pulmonary capillaries walks through it.
Walking Oximetry and Oxygen Titration
The six-minute walk test is also how the practice decides whether you need home oxygen. You walk as far as you comfortably can for six minutes. If your oxygen saturation drops below 89%, staff pause, apply oxygen and adjust the flow until your level stays above 90%. Bring your own portable oxygen and any walking aid you normally use. Low oxygen matters beyond breathlessness, because it tightens the lung blood vessels, a process explained in our piece on hypoxia and pulmonary vasoconstriction.
Overnight Pulse Oximetry
This is a simple home test. You pick up a recorder with a finger clip, wear it overnight, and return it by noon the next day to the drop box on the left side of the building, even if you picked it up on a Friday. It screens for oxygen dips during sleep and can flag who needs a full sleep study.
Accredited Sleep Lab
The overnight sleep lab, Sleep Solutions of Fredericksburg (also known as the Sleep Disorder Center of Fredericksburg), is in the same building. It was founded in 2006 and accredited by the American Academy of Sleep Medicine in 2010. It is technically a separate business, but several PAF physicians are associated with it. The lab evaluates obstructive sleep apnea, narcolepsy, periodic limb movement disorder, REM sleep behavior disorder, insomnia, sleepwalking and snoring.
Mayo Clinic lists the classic warning signs of obstructive sleep apnea: loud snoring, breathing pauses a partner notices, waking up gasping, morning headaches and heavy daytime sleepiness. For people who cannot tolerate CPAP, the practice’s sleep specialists work with a local surgeon on Inspire hypoglossal nerve stimulation therapy.
If you use a Philips CPAP or BiPAP machine, the practice’s website still carries a notice about the Philips device recall. Ask your provider whether your device needs attention.
Bronchoscopy and EBUS
Bronchoscopy lets the doctor look inside your airways with a thin camera to investigate lung masses, infections or a stubborn cough. The practice also performs endobronchial ultrasound (EBUS), which uses ultrasound to sample lymph nodes and lesions near the airways. These procedures are done as outpatients at the hospital.
Lung Cancer Screening
The practice offers lung cancer screening for current and former smokers. According to the CDC’s lung cancer screening guidance, the U.S. Preventive Services Task Force recommends a yearly low-dose CT scan for adults who meet all three criteria below.
| Criterion | Requirement |
|---|---|
| Age | 50 to 80 years |
| Smoking history | 20 pack-years or more (for example, 1 pack a day for 20 years) |
| Current status | Smoke now, or quit within the past 15 years |
Screening usually stops once you turn 81, reach 15 years without smoking, or develop a health problem that would rule out lung surgery.
Critical Care Medicine
Pulmonary Associates of Fredericksburg partners with Mary Washington Healthcare to staff its hospital ICUs with critical care physicians. That continuity is a real advantage for people with advanced lung disease, severe asthma or recurrent pneumonia, where hospital stays can happen.
What to Expect at Your First Visit

- Get a referral if your plan needs one. Your doctor’s office can send it through Phreesia, the online request form, or by fax to (540) 372-3525. See the practice’s physician referrals page.
- Book by phone. Call (540) 899-1615, ideally outside the noon to 1:00 p.m. lunch hour.
- Print the forms. Fill in the new patient packet and the medication profile from the practice website and bring them with you.
- Gather records. Bring chest X-ray or CT reports (or the disc), prior breathing tests, and a full list of medicines, including every inhaler.
- Prepare for testing. If breathing tests are booked, wear loose clothing, avoid smoking beforehand, skip caffeine, alcohol and a big meal for 2 hours, and avoid your rescue inhaler for 12 hours unless you truly need it. Keep taking your regular inhalers unless your doctor says otherwise. Allow about an hour for full lung testing and 30 minutes for a walk test.
- Leave with a plan. Expect a history and exam, possible tests the same day or soon after, and a follow-up visit to go over results.
The office asks for at least 24 hours’ notice to cancel or reschedule. Late cancellations incur a fee.
Insurance and Billing
The billing team files most claims electronically, including Medicare and Medicaid. The practice’s insurance and billing page lists participation with plans including:
- Aetna (HMO and PPO), Anthem and HealthKeepers
- Medicare and Medicare Railroad, plus Medicaid
- Humana (Gold, Choice and Choice PPO) and Kaiser
- CareFirst, Optima Health, Virginia Premier and Southern Health (UVA employees)
- UnitedHealthcare and UMR (Mary Washington Healthcare employees)
- MultiPlan, PHCS and Beech Street networks
Two important notes: the practice has been out of network with Cigna since June 1, 2021, and some plans on the list carry a “check with your plan” caveat. Call your insurer before booking. Bills can be paid through the YourHealthFile patient payment portal linked on the practice website.
When to See a Pulmonologist
Common reasons to book with a lung specialist include:
- A cough lasting more than 8 weeks
- Breathlessness with stairs or everyday activities
- Wheezing or chest tightness that keeps returning
- An abnormal chest X-ray or CT, including a lung nodule
- Loud snoring with daytime sleepiness
- Low oxygen readings on a home pulse oximeter
- Ongoing breathlessness after a blood clot, or follow-up after pulmonary embolism treatment
Go to the emergency room instead if you have sudden shortness of breath, chest pain that worsens when you breathe, coughing up blood, or a swollen, painful leg. These can be signs of a pulmonary embolism. Learn how to know if you have a pulmonary embolism and how doctors confirm one.
Other Pulmonary Options in the Fredericksburg Area
Fredericksburg has several other lung practices if you need a second opinion or a shorter wait. Mary Washington Healthcare runs its own pulmonology group, and independent practices such as Virginia Pulmonology and Critical Care (on Spotsylvania Parkway) and Advanced Pulmonary Critical Care also serve the region. Check each one’s current hours and insurance directly.
