My passion is to take care of children and adolescents with rheumatologic/autoimmune disorders. I strive to create a strong therapeutic alliance with my patients and their family, improving their quality of life and ensuring the best outcome.  Compassionate, comprehensive and excellent patient care are my goals. 

Clinical Interests:

I care for all rheumatologic conditions ranging from Kawasaki disease, Juvenile Idiopathic Arthritis and Lupus to the rarer diseases such as Systemic Scleroderma and Auto-inflammatory disorders. Enjoy working with multiple other subspecialties and disciplines on complex cases with unknown diagnoses.

Research Interests:

Research interest include clinical trials of new therapeutic agents as well as outcomes research. I am very interested quality improvement and guideline implementation to provide the best evidence based care for the rare diseases seen in pediatric rheumatology.  Medical and community education are also of great interest.
