Diversity Matters: The University of Colorado Denver - Anschutz Medical Campus is committed to recruiting and supporting a diverse student body, faculty and administrative staff. The university strives to promote a culture of inclusiveness, respect, communication and understanding. We encourage applications from women, ethnic minorities, persons with disabilities and all veterans. We are committed to diversity and equality in education and employment.

Find out more at the Anschutz Medical Campus Office of Diversity & Inclusion.



The Section of Pediatric Pulmonary Medicine believes that Diversity, Equity, and Inclusion are a core pillar of our section that is included as part of our strategic plan. 



Our current activities to advance this mission include:

Breathing Institute Equity Council

Vision: Creating a culture that centers equity and justice

Mission: Centering equity, inclusion, and diversity in all aspects of pediatric pulmonary care, research, education, and advocacy


Dedicated Leaders in DE&I Within Pulmonary

  • Dr. Robin Deterding is the executive sponsor for DE&I activities within pulmonary
  • Breathing Institute Equity Council led by Arthur McFarlane, Su Linstrom, and Shanaj Grewal
  • Dr. Stan Szefler is co-PI of an NIH grant looking at asthma and disparities for children

Holistic Review Process for Fellowship Applicants

  • USMLE Scores are removed from application
  • Headshots are removed from application
  • Volunteer activities and entire application are weighted along with academic qualities
  • DE&I continuing education for entire department, and in particular faculty & fellows involved in the interview process

Pulmonary Representatives on Hospital Diversity & Inclusion Leadership Committees

Diversity, Equity, & Inclusion Resources on Campus

Community is important, not only within pulmonary, but within the hospital and the medical campus.


Community in Aurora

  • Pulmonary is proud to have created several novel community programs such as
    • AsthmaCOMP-Colorado Comprehensive School-Centered Asthma Program
    • Just Keep Breathing- asthma education for families
    • Political advocacy with the capitol including vaping mitigation and smoking cessation

Our patient population is diverse and reflects the diversity found in the city of Aurora: 16% of residents identify as Black or African American, 28% identify as Hispanic or Latino, 6% identify as Asian, and 5% identify as two or more races.


Deboer Hawkins

Education is a cornerstone of our department. Our conferences are led by faculty and multi-disciplinary leaders.


Course Work


Clinical Scientist Master’s Program

The MSCS degree program is graduate level course work for individuals who will pursue clinical research such as translational clinical research, clinical trials, or outcomes research. This program is a unique opportunity to provide a comprehensive exposure to training required for a successful career in clinical research. Funding for this program is provided through grant support or directly by the Department of Pediatrics.


Subspecialty Excellence in Educational Leadership & Scholarship (SEELS) Program


The goal of SEELS is to equip pediatric subspecialty fellows with the necessary knowledge/skills/attitudes for success as future medical educators through educational scholarship and professional identity development, faculty and peer mentorship, and engaging in an educational community of practice.  


SEELS scholars will complete this 18-month program that will begin during the second year of fellowship for three-year fellowship programs.The curriculum will include in-person educational sessions for the first 12 months, along with self-directed independent study, a scholarly project, and mentorship throughout the entire 18 months. Educational content will be delivered through approximately once per month sessions including work-in-progress sessions as well as individual meetings with SEELS Program leaders and mentors.


SEELS Program



Our program provides regular environments for learning the latest in pulmonary science, innovation, and technology. Some of these meetings include:



Pediatric Pulmonary Grand Rounds (weekly)

This conference is built to teach on core topics of pulmonology, as well as the more rare cases that we see at our hospital. This conference includes case presentations, fellow "research in progress" updates, morbidity and mortality conferences, and lecture topics designed to complement your clinical experience.

 Western States(monthly)

This regional conference is hosted by University of Arizona via Zoom. It provides a unique opportunity to learn about unusual cases from other centers as well as different centers’ approaches to diagnosis and management. Colorado has a strong presence here with at least one of our fellows presenting annually.


 Journal Club (monthly)


Fellows work in tandem with faculty and a biostatistician to present appropriate journals based on the newest publications. Journal club is essential in teaching a fellow how to review a paper and critically analyze the literature. Fellows co-lead journal club about twice a year.

Pulmonary/Radiology/Pathology Conference (monthly)


This multidisciplinary conference focuses on discussion of complex patient cases that required a lung biopsy, imaging, or that resulted in an autopsy. The conference involves a chalk talk review of the patient case and appropriate literature.

Research Council (monthly)  

This conference focuses on fellow training in research, and how to help fellows progress towards the successful completion of their research project. Senior fellows present once a year with pearls/lessons learned about their current research.

Department of Pediatrics Fellowship Retreats

These seminars are training sessions provided for all fellows once or twice a year. They focus on topics like resiliency, personal finance, leadership training, employment contracts, grant writing, bioethics, and much more.

National Conferences


All fellows will be supported to attend either the North American Cystic Fibrosis Conference (NACFC) or the American Thoracic Society Conference (ATS) each year, as long as they have submitted an abstract or poster. Additional conferences may be arranged at the discretion of the faculty research mentor and the fellowship director.

Our fellowship curriculum is designed to customize the learning experience to each fellow’s interests and career goals. For fellows who are interested in furthering their education through coursework, some pulmonary-specific resources are listed below. There are numerous resources also available through the University of Colorado.

Cotton Conference


Cotton 1978 

Cotton Conference 2024 Program

The Breathing Institute hosts a yearly mountain retreat and conference called the “Cotton Conference.” Aptly named after the founder of our fellowship and a pioneer in the field of pulmonary medicine, our 2024 Conference marks the 34th anniversary of this historic tradition. This event serves as an opportunity to refine fellow presentation skills, learn from national pulmonary leaders, and engage with fellows past and present. We take great pride in hosting a nationally recognized conference that offers a yearly opportunity for research presentation and rejuvenation. All fellows in our program present along with our faculty members, researchers, and a nationally recognized guest speaker. Former fellows, along with clinicians and researchers working in all corners of pulmonary medicine from around the United States, regularly join our group for a weekend in the mountains.

Diversity / Equity / Inclusion


We are committed to creating a diverse environment for students, residents, fellows, and faculty. We believe that an environment of inclusiveness and respect promotes excellence and that a setting where diversity is valued leads to the training of physicians who are prepared to practice culturally effective medicine and meet the needs of the various populations we serve. Visit our Diversity, Equity, and Inclusion webpage for more....

Well-Being / Resilience

Be well

By embracing wellness and improving personal resiliency, physicians can reconnect with the meaning of their work and fend off stress. Reducing or eliminating burnout also has practical implications for the entire department such as improving patient safety, student advancement, and the overall campus environment.
