Awards and Accolades

What are some of the specific conditions you treat?

Asthma, chronic cough, recurrent pneumonia, exercise intolerance, habit cough, and vocal cord dysfunction are some of the respiratory conditions that I regularly treat. From a sleep standpoint, I treat narcolepsy, postural orthostatic tachycardia syndrome (POTS), obstructive sleep apnea, restless legs syndrome, and congenital central hypoventilation syndrome (CCHS).

What would you like patients to know about your approach to care?

Spending enough time, asking enough questions, and getting to know a person is the key to providing the best possible care. Eye contact is also greatly important when treating and communicating with a patient.

    Love dr. Kass and so does my almost 3 year old soon. He actually looks forward to seeing him. As parents this is a huge weight off our shoulders to have full faith in a doctor treating our son!

    Dr. Kass was wonderful. He was personable and made my daughter feel comfortable. It was a great way with children and wonderful bedside manner. We were not rushed. He took the time to listen to all concerns, asked extensive questions, and took his time with the exam and treatment plan. I would recommend him to anyone.
