The outpatient experience is balanced with participation in the inpatient-based Allergy and Immunology Consult service at Children’s Hospital Colorado.  During their first year, fellows will each provide 20 weeks of coverage on the consult service with attending supervision.

First Year Outpatient  

Pediatric Continuity Clinic:  This half-day per week clinic is scheduled weekly for the two years of fellowship.  Fellows will have the opportunity to follow a cohort of patients for up to 2 years.  The major goal is to gain experience and expertise in the diagnosis and management of common pediatric allergic diseases, as mentioned in the Fellowship Program Aims (see Program Overview).   Fellows will also develop the procedural skills required of an Allergist/Immunologist which includes:

    • Performance of and interpretation of epicutaneous skin testing,
    • Lung function testing
    • Allergen immunotherapy
    • Prescription of Biologic therapy for allergic diseases
    • Food and drug challenge testing

Adult Continuity Clinic:  For this half-day clinic/per week over the two years of the fellowship, our fellows will develop expertise in caring for adults with allergic and immunologic diseases.  This clinic is based at UCH, which is adjacent to CHCO.  They will become familiar with the diagnosis and management of adults with:

  • Aspirin exacerbated respiratory disease, including aspirin challenges/desensitization
  • Allergic bronchopulmonary aspergillosis
  • Fixed obstructive lung disease
  • Chronic rhinosinusitis
  • Drug allergy
  • Insect sting allergy
  • Hereditary angioedema
  • Primary and acquired immunodeficiencies. 

Immunodeficiency Clinic:  This one half-day clinic will be attended by every fellow for 12 months over the 2 year fellowship. Fellows will develop expertise in the diagnosis and management of a number of immunodeficiency disorders including:

    • B-cell and T-cell immunodeficiencies
    • Severe combined immunodeficiency
    • Complement component deficiencies
    • Abnormalities of neutrophil number and/or function. 
    • Prescription of immunoglobulin replacement therapy.


General Pediatric and Adult Allergy Clinics:  Fellows will work directly with all of the attendings in their clinics.  This will provide the fellows a chance to see how each faculty member approaches allergic and immunologic diseases and also to gain from their unique and extensive knowledge of their specific interests. 

First Year Inpatient / Consult Service

Each first year fellow will provide 20 weeks of coverage for the inpatient Allergy & Immunology consultative service at Children’s Hospital Colorado. The Second Year fellows will also provide 6 weeks of inpatient coverage of the consult service as well.  The emphasis during this rotation will be on specialty consultation within a large, full-service academic Children's Hospital.  During this rotation, the fellow will be responsible for:

  • Answering calls from referring physicians within the region who seek advice on their patients with allergic and immunologic disease
  • Performing Allergy/Immunology consults on the inpatient units
  • Drug desensitizations.

An attending will always be available to supervise all consults and will be available to provide guidance with any telephone calls the fellow may receive.


Second Year of Fellowship Overview

The second year is largely focused on pursuit of scholarly activity and education. Second year fellows will continue to attend the Pediatric and Adult Continuity Clinics as well as the Immunodeficiency clinic and electives which are in line with their career interests. They will also spend one month performing consults on hospitalized adults with allergic and immunologic diseases at the UCH under the direct supervision of the adult allergists at UCH. 

Second Year Outpatient Clinics

The major clinical goal during the second year is for the fellow to develop increasing expertise in the diagnosis and management of allergic and immunologic disorders in both children and adults. They will attend three one half day clinics during their second year, which include:

  • Pediatric Allergy Continuity Clinic

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.
