View All PlansAbout Nathan Kraynack, MD
Nathan C. Kraynack, M.D. was appointed to Cleveland Clinic Children’s in 2013 to the Pediatric Institute and Center for Pediatric Pulmonary Medicine. He is the Director of the Cleveland Clinic's accredited Cystic Fibrosis Center and the Director of the Pediatric Cystic Fibrosis Program at Cleveland Clinic Children's.
He has been board-certified in pediatrics and pediatric pulmonary medicine. He cares for children and young adults with all forms of pediatric lung conditions such as asthma, bronchopulmonary dysplasia, chronic lung disease of prematurity, chronic respiratory failure, and those children requiring technological assistance to breathe effectively. In particular, he has a keen interest in children with Cystic Fibrosis, other forms of bronchiectasis, end stage lung disease, and children and young adults with pulmonary disease as a complication of bone barrow and stem cell transplant.
Serving as the head of a large accredited Cystic Fibrosis Center for almost ten years, he has a wealth of experience in caring for these patients with their complex medical needs. He and his team realized that inconsistent care for this condition across Cystic Fibrosis Care Center was prevalent and may be contributing to variable outcomes1. Heading a multidisciplinary team of caregivers, his team developed standardized protocols for cystic fibrosis care that had not previously been used and were associated with dramatic improvement in patient outcomes at their center. These protocols have since been adopted at other care centers nationally and internationally on at least three continents. His passion for standardized care has extended to nutritional protocols for patients with cystic fibrosis, non-cystic fibrosis bronchiectasis, inpatient management for patients with cystic fibrosis, asthma, and those patients with chronic respiratory failure and lung transplantation.
Dr. Kraynack has been named one of the Best Doctors in America since 2009. He has been a principal investigator of translational research trials and a number of multicenter clinical trials for patients with Cystic Fibrosis. As an Associate Professor of Pediatrics at the Cleveland Clinic Lerner College of Medicine and Case Western University and the Northeast Ohio Medical University (Rootstown, OH), he is active in medical education of medical students and pediatric resident physicians.
An invited lecturer at national and international medical meetings, Dr. Kraynack is a recognized expert in the field of Cystic Fibrosis and the implementation of Quality Improvement programs to improve patient outcomes.

Cleveland Clinic physicians and scientists may collaborate with the pharmaceutical or medical device industries to help develop medical breakthroughs or provide medical expertise or education. Cleveland Clinic strives to make scientific advances that will benefit patient care and support outside relationships that promise public benefit. In order for the discoveries of Cleveland Clinic physicians' and scientists' laboratories and investigations to benefit the public, these discoveries must be commercialized in partnership with industry. As experts in their fields, Cleveland Clinic physicians and scientists are often sought after by industry to consult, provide expertise and education.
To assure professional and commercial integrity in such matters, Cleveland Clinic maintains a program that reviews these collaborations and, when appropriate, puts measures in place to minimize bias that may result from ties to industry. Cleveland Clinic publicly discloses the names of companies when (i) its physicians/scientists receive $5,000 or more per year (or, in rare cases, equity or stock options) for speaking and consulting, (ii) its physicians/scientists serve as a fiduciary, (iii) its physicians/scientists receive or have the right to receive royalties or (iv) its physicians/ scientists hold any equity interest for the physician's/scientist's role as inventor, discoverer, developer, founder or consultant.* In publicly disclosing this information, Cleveland Clinic tries to provide information as accurately as possible about its physicians' and scientists' connections with industry.
As of 3/20/2025, Dr. Kraynack has reported no financial relationship with industry that is applicable to this listing. In general, patients should feel free to contact their doctor about any of the relationships and how the relationships are overseen by Cleveland Clinic.

Public Health Service-Reportable Financial Conflicts of Interest. Cleveland Clinic scientists and physicians engage in basic, translational and clinical research activities, working to solve health problems, enhance patient care and improve quality of life for patients. Interactions with industry are essential to bringing the researchers' discoveries to the public, but can present the potential for conflicts of interest related to their research activities.
