Allergy and Immunology Fellowship at Children's


Children's Hospital Colorado in Aurora, Colorado


Program Overview

Our program is primarily based at Children’s Hospital Colorado (CHCO), with adult clinics and consultative services at the University of Colorado Hospital (UCH), both are based at the Anschutz Medical Campus in Aurora, Colorado. This is an ACGME-accredited, University of Colorado Program, Allergy and Immunology Fellowship (Program Number 0200700087). 

Children’s Hospital Colorado has been consistently ranked in the top 10 Children’s Hospital’s in the United StatesIn addition to being one of the newest Children’s Hospitals, it is among the largest and has a large catchment area with no other major Children’s Hospitals within a 500-mile radius.  

The Allergy/Immunology Section at Children’s Hospital Colorado was founded in 2013 and the Allergy and Immunology Fellowship started in 2016.  Despite both being relatively new, our faculty have over 100 years of combined experience in every facet of Allergy and Immunology, with:

  • 8 primary pediatric allergy faculty
  • 2 primary clinical pediatric immunology faculty
  • 3 primary adult allergy and immunology faculty
  • 1 PhD clinical psychologist
  • 1 PhD dietician

We opened a new state of the art Allergy and Immunology Center at CHCO in 2018.  This center is one of the largest facilities in the country, providing an opportunity to synthesize research, education, and clinical work in one space for our fellows.  The Allergy and Immunology Center features.

  • 12 clinic exam rooms
  • 12 food/drug challenge rooms
  • Dedicated immunotherapy/biologic administration area
  • Dedicated educational conference room

First Year of Fellowship Overview

Much of the first year of fellowship will be devoted to direct clinical care.  First Year Fellows will spend most of their time in several outpatient clinic settings, including:

  • General allergy clinic
  • Pediatric and adult continuity clinics
  • Immunodeficiency clinic

In addition, fellows will attend a number of elective clinics including:

  • Pulmonary
  • Rheumatology
  • ENT
  • Eosinophilic Gastrointestinal Diseases clinic

The outpatient experience is balanced with participation in the inpatient-based Allergy and Immunology Consult service.  During their first year, the fellows will alternate providing the primary coverage for the consult service with attending supervision.

Lastly, each First Year Fellow will have a 3-month research block in the second half of their first year (see Research & Scholarly Activity tab).


First Year Outpatient Clinics

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
    • 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.  Each Fellow will be precepted by all three of the adult attendings in 4-month blocks over two years.  This will provide an opportunity for each fellow to gain knowledge from each of the attendings as they all have different clinical and research interests.  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 each year of 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. 

Procedural skills unique to this rotation include performing and interpreting delayed type hypersensitivity testing and the administration of intravenous gammaglobulin and other biologics.


General Allergy Clinics:  The number of General Allergy Clinics will range from none during the 3-month research block to 5 one-half day clinics/week.  It is designed to have the Fellows 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. 

Specialty Clinics:

    • Pulmonary
    • Rheumatology
    • ENT
    • Eosinophilic Gastrointestinal Disorders Clinic
    • Bone marrow transplant clinic

First Year Inpatient Allergy/Immunology Consult Service

This is an approximate 6-month clinical rotation during the first year, with coverage alternating weekly between the two First Year fellows.  The Second Year fellows will also provide limited 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 advise 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 research and other scholarly activities. Second year fellows will continue to attend the Pediatric and Adult Continuity Clinics as well as the Immunodeficiency clinic. 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
  • Adult Allergy Continuity Clinic
  • Immunodeficiency Clinic


Second Year Inpatient Experience

Each fellow will spend one month on the Adult Allergy Consult Service at UCH. During this rotation, fellows will:

  • Develop knowledge and skills in working with and instructing primary care providers in adult allergy, asthma, and immunology care
  • Continue to develop expertise in interacting, as a consultant with primary care providers
  • Provide consultation for patients admitted with immunologic, allergic and asthmatic diseases
  • Perform drug and aspirin desensitizations An attending from the UCH always available for guidance and backup of all consults.


We have a robust educational curriculum which utilizes varied teaching formats to cover all fundamental Allergy & Immunology topics as described below:

  • Fellow Boot Camp Series: Link to schedule
    • Clinically oriented lecture series in July and August which provide fellows with the fundamental knowledge needed when caring for patients with Allergic and Immunologic concerns.

        • CU Graduate School: An overview of Human Immunology.
        • Our second-year fellows are allowed the opportunity to audit the Graduate School course to review the basics of Immunology.


Research & Scholarly Activity

All fellows participate in scholarly activity under faculty supervision with the goal of providing knowledge of the basic principles of research, including how research is conducted, evaluated, explained to patients, and applied to patient care.

Fellows regularly present their scholarly activity locally as well as at national meetings such as the American Academy of Allergy, Asthma, and Immunology (AAAAI) and American College of Allergy, Asthma, and Immunology (ACAAI).

Scholarly activity can include, but is not limited, to the following:

  • Laboratory based
  • Epidemiologic
  • Quality Improvement
  • Clinical Investigation-Based


We have the following resources to ensure successful fellow scholarly activity:

  • Annual Research Symposium:
    • Faculty present on projects (ongoing and future) that would have opportunities for fellow involvement. We encourage fellows to select or design a project which is aligned with their interests.


  • Scholarly Oversight Committee:
    • Functions to oversee that fellow scholarly projects are appropriate and meeting expectations for graduation.
    • Comprised of Research and Fellowship Leadership Faculty


  • Protected Time:
    • Fellows have a 3-month block in their first year with limited clinical responsibilities to focus on scholarly activity.
    • A larger part of the second year is protected and dedicated to progression of their scholarly project.


  • Protocol Development Workshop:
    • Fellows are encouraged to apply fort his hands-on workshop through the CU graduate school.



First Year Research Block

During this 3-month block of protected time during the second half of the fellows’ first year, the fellows are expected to:

    • Identify a research project and research mentoComplete any orientation or safety procedures in the laboratory and/or clinical research settings, as applicable
    • Write a research proposal for submission and presentation to the faculty by June of their first year.

It is during this block of time, that the fellow can also spend time performing other Scholarly activities such as preparing for the in-training exam, working on formal presentations, and their research presentation.


Second Year Research Expectations

A high quality clinical or basic science research experience is the major goal of the second year of fellowship and will account for the majority the Fellow’s efforts.

  • Every Second Year Fellow is expected to present their research at a regional or national meeting and have a manuscript ready for submission by the end of their Second Year.  They will also be encouraged to write case reports, and to assist the Attending’s in writing book chapters and topical reviews.
  • Fellows interested in a career in Academic Medicine will begin planning on submitting grants and/or Career Development Awards with assistance from their Research Mentor.
