Dr. Liss is one of the smartest doctors I have ever met. He listened to me, ran tests and found what other doctors had missed. He always took enough time and was able to explain things in ways that I understood. He's a remarkable physician.

I have been a patient of Dr. Liss for three (3) years now. He exudes knowledge and administers and prescribes treatment with great care and takes the time to assure that I, as the patient, understand not just the diagnosis, but also the "why's" of treatment. I wish all physicians I see were so thorough and caring.

I'm not used to providers who so truly seem to care for me and my welfare. Dr. Liss and his staff not only focused on my lungs and sleep medicine issues but made sure I knew who to talk to about my other problems.

Dr. Liss moved to Portland, OR and works at Vibra Speciality Hospital. He is so skilled and got me to breathe on my own without a ventilator after a long hospital stay in the ICU. He also started me on auto-BiPAP for my sleep apnea so I can stay healthy and out of the hospital. I feel like he saved my life.

Dr. Liss is truly a masterful doctor. He is incredibly knowledgable and fantastic at explaining and educating patients, staff, and students. He remembers important details about my life and my health from visit-to-visit. He even follows up between visits, sometimes calling to see how I am doing. If laughter truly is the best medicine, he has got that covered also. I feel that he is truly there for me, and I actually look forward to my visits with him. Dr. Liss has got it all; I cannot recommend him highly enough!

I spent a minimal amount of time in the waiting room. I have met with Dr. Liss a few times and every time he takes the time to talk with me, answer all questions and is never in a rush to fly out of the room to see other patients. Very professional, knowledgable and overall a nice guy.
