COVID-19 Guidelines

CU Doctors are here for you!
Our clinics are open and able to serve you during this time for urgent in-person visits as well as virtual health services. Please call our clinics directly to schedule an appointment for both in person and virtual health.

Our number one priority is the health and safety of our patients, their family members, as well as our health care team. To honor this commitment we have implemented the following procedures:

  • Non-urgent medical appointments should be converted to telehealth visits or rescheduled if telehealth is not feasible.
  • Please bring your own face mask or covering to wear. Patients checking in must tell staff if they have: A fever, cold symptoms (cough, sore throat, runny nose, shortness of breath); Flu symptoms (fever, chills, body aches, etc.).
  • Adult patients may be allowed one asymptomatic person (at least 17 years old) for support; however, we reserve the right to deem a support person unnecessary at any time.
  • Pediatric patients may be allowed one asymptomatic adult (i.e. parent, guardian) for support.
  • For pediatric patients, please check the Children's Hospital Colorado website for updated COVID-19 related patient information.

Please call us about your current health care concerns. Please take care in following current public health guidelines. Please visit the Colorado COVID-19 website, for more information.

Thank you for doing your part to help keep everyone safe and healthy!

Clinical Interest for Patients
My primary clinical interest is food allergy - from the time point of accurate diagnosis, usually at a young age, and the multidisciplinary care of the patient to include psychosocial and dietitian support, through the natural history and hopefully resolution of the allergy. I also believe in helping the patient and the family navigate the management of food allergy from the young age, through important transitions to self-care of school-age children, and then independent living with food allergy as adolescents and adults.

Care Philosophy
When caring for any patient with any medical problem, patient care should involve not just treating the condition, but how that condition affects the patient AND the family as a whole. Treating food-allergic patients requires us to do this, as food allergy affects all aspects of life and the entire family. We are fortunate that Children's Hospital Colorado provides us with the tools to take a multidisciplinary treatment approach to our patients and families, with a team of staff that includes psychosocial support, dietary management, and the most recent food allergy research. And now Children's Hospital Colorado has paired this multidisciplinary care with a state of the art Allergy and Immunology Center, featuring one of the largest food challenge and research units in the world.

Information for Referring Providers

Clinical Interests for Referring Providers
My primary clinical interest and focus of research is food allergy.

Research Interest for Referring Providers
My research focuses on food allergy, in particular peanut and tree nut allergies. I am interested in why certain patients with food allergies outgrow them more readily and sooner than others. I am an investigator in treatments for food allergy, including oral, sublingual, and epicutaneous immunotherapies.
