Reston Location - Pulmonary and Critical Care Associates & Sleep Diagnostic Center

I have been a patient of Dr. Rennert for approximately 8 years. In this time the doctor has helped me prolong my working career and life through medication therapy and education. He is kind, empathetic and knowledgeable in his field of expertise. I would gladly recommend him to all family and friends suffering from pulmonary or coronary diseases. He is truly blessed in his field. Thank you Dr. Rennert!

Wonderful office staff. Never a long wait. Dr. Naghshin spends as much time as you need. Always a pleasant experience!

The best care for sleep disorders. Down to earth, explained everything I asked about. Friendly office staff and nurses too.

After 3 weeks of respiratory and sinus infections and multiple visits to other doctors, I saw Dr. Tramontana. A week later, I am finally better. Dr. Montana asked many questions to understand my symptoms, previous treatment, and background. She is also performing follow-ups to ensure that we get ahead of what may have been the root cause. I am very grateful for having found Dr. Tramontana. Five stars all the way.

I have seen Dr Jane Tramontana twice. She is an exceptional person and doctor. She explains things well, listens to the patient with compassion, fully answers questions , gives thorough examinations,and is an upbeat and personable person. I highly recommend her.

What a relief to see a doctor who takes his time, listens, is friendly, and provides extremely helpful care. He even takes handwritten notes and was interested in medical history. The new patient coordinator was fantastic, along with other staff who helped with scheduling, assisting with the patient portal, etc. Thank you, Dr. Rennert, for providing a kind of care that is SO needed.

My first time seeing Dr. Naghshin and he is very thorough and explained what I needed before my surgery..I am grateful! He explains and makes sure you understand and cares! You never feel rushed with their offices. I highly recommend him and his team for your care.

Wonderful office staff. Never a long wait. Dr. Naghshin spends as much time as you need. Always a pleasant experience!
