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
I am the leader of our solid tumor team, so my clinical work focuses on the treatment of childhood solid tumors outside of the brain and spinal cord, such as neuroblastoma, Wilms tumor, pediatric sarcomas, and many other tumor types. I have a particular interest in histiocytic disorders and am a member of the Histiocyte Society. Outside of my clinical work, I am interested in medical education. I teach at the University of Colorado School of Medicine, and I am director of our Pediatric Hematology/Oncology Fellowship Program, training the next generation of pediatric hematologist/oncologists.

Care Philosophy
Solid tumors are rare in kids and every case is unique, so treatment has to be individualized and requires a team approach. We have a big, multidisciplinary team here to address the many aspects of cancer treatment. A key additional component to that team is the family. It is essential that the family understands what is going on and participates in the decision-making process so that the priorities and goals of the patient are always kept at the forefront. I went into pediatrics because I love the refreshing innocence and optimism of children, who have their full lives ahead of them. And, I want to do everything I can to make sure that they reach their full potential. Cancer can tragically cut short the lives of young people, cheating the world of all of the good things they would have accomplished. My goal is to do everything in my power to prevent that, through cutting edge clinical science coupled with compassionate, personalized care. A diagnosis of cancer in a child is a scary thing and is likely one of the hardest things that a parent will ever have to face. That is something I strive to remember every time a new patient walks into my office. My job is not only to treat the patient’s disease but to give the family hope and to make sure they know that they have a whole team of people here to support them through their journey.

Personal Interests
Outside of medicine, I like to garden, spend time with my family, and am an avid musician.
