The Division of Pediatric Endocrinology & Diabetes

The work of this division successfully combines the worlds of investigation, innovation, and clinical care to improve the diagnosis and treatment of endocrine disorders.

Patient Care

The Division of Pediatric Endocrinology and Diabetes at Stanford has a long tradition of providing quality clinical care of children and adolescents across the broad range of pediatric endocrinology disorders.

Patients, contact the endocrinology & diabetes clinic.

More about patient care 


The Division of Pediatric Endocrinology and Diabetes at Stanford is actively involved in basic, translational, and clinical research.



The Division's Fellowship Program ensures future generations of physicians can achieve an in-depth understanding of patient care surrounding a wide range of pediatric endocrinology disorders.


The Division of Pediatric Endocrinology is excited to announce a special Guest Seminar as part of our Basic Research Club which is of interest to the wider faculty. You are warmly invited to join us to hear from Ron Rosenfeld, Emeritus Adjunct Professor of Pediatrics at Stanford University & Emeritus Chair of Pediatrics at Oregon Health Sciences University. This will be a rare opportunity to hear from a clinician scientist who has contributed so much to our understanding of the endocrine basis of growth and development.  Ron was based at Stanford in the Department of Pediatric Endocrinology for many years before taking up the Chair of Pediatrics at Oregon Health Sciences University.   

Date:  Tuesday, August 25th  4:15 to 5:00 pm

Dr. Addala and Dr. Prahalad's most recent paper in the ADA Daily News Update. 

Steady CGM, health insurance crucial for youths with T1D

A study in Pediatric Diabetes found that children with type 1 diabetes who had public health insurance experienced higher A1C levels when they stopped using continuous glucose monitoring and continued having higher A1C levels even when access to CGM was restored. The findings, based on data from 264 children with type 1 diabetes who had public health insurance, also revealed that insurance-related reasons were behind 65% of the CGM interruption cases among the study participants who had been using CGM.

David Scheinker, PhD joins the Division of Pediatric Endocrinology and Diabetes

Concurrently with his appointment to Pediatric Endocrinology, David Scheinker is an Adjunct Professor in the Department of Management Science and Engineering and The Director of Systems Design and Collaborative Research at the Stanford Lucile Packard Children's Hospital. His appointments in the School of Medicine, School of Engineering, and the Children's Hospital are designed to facilitate collaboration between the three institutions. To foster such collaboration he founded and directs SURF Stanford Medicine, a group that brings together students and faculty from the Schools of Medicine and Engineering with nurses and administrators from the Children's Hospital to improve the quality and reduce the cost of care using operations research methodology. SURF is currently working with other faculty in  Pediatric Endocrinology to develop tools to detect and predict deteriorating glucose control and develop personalized care responses for Type 1 Diabetes using continuous glucose monitor data. David also serves on the faculty of Stanford's Clinical Excellence Research Center where he works on transforming SURF's hospital projects into broader interventions that have the potential to reduce the nationwide cost of high quality care.

Dr. Eric Appel now has a ‘courtesy appointment’ in the division

The Appel lab develops new technologies to enable next-generation biopharmaceutical formulations. Dr Appel has a strong interest in engineering new insulin formulations that can address long-standing challenges with current formulations to enhance the management of diabetes. Dr Appel’s research is funded by an R01 from the NIDDK, a Junior Faculty Development Award from the American Diabetes Association, and a Stanford Diabetes Research Center Pilot & Feasibility award funded by the Maternal Child Health Research Institute. Dr Appel’s research on insulin  formulations complements the clinical research in the division on diabetes technology including work on the artificial pancreas.Dr Appel serves as a basic science advisor for fellows and faculty in the area of insulin formulations and an educational resource for trainees and faculty for the science of insulin and other hormonal therapies that are essential to clinical practice in pediatric endocrinology.

Division Activities

It's a Match! - Holly Cooper & Walter Zegarra to Join Fellowship Program

We are thrilled to announce that on December 13, our fellowship training program matched two out of two positions. We look forward to welcoming Holly Cooper, MD from UCLA and Walter Zegarra, MD from University of Miami to our team beginning July 7th, 2018.

Division Founder's Legacy Honored

50 Years Ago in The Journal of Pediatrics is a brief reflection on the prolific and ground-breaking work of Raymond Hintz, MD, founder of the Division of Pediatric Endocrinology at Stanford School of Medicine and author of over 350 publications.

Maria Chang, MD (fellow), Darrell Wilson, MD (faculty), and David Maahs, MD, PhD (chief) recall Hintz' first publication, Familial Holoprosencephaly with Endocrine Dysgenesis (1968), in a December 26, 2017 Journal of Pediatrics column. Read more about Hintz at Stanford Medicine Scope.


We're Open! - New Packard Children's Hospital

Lucile Packard Children’s Hospital Stanford has created one of America’s most technologically advanced, family-friendly and environmentally sustainable hospitals for babies, children and pregnant women. The new hospital, opened its doors to patients on December 9, 2017 adding 521,000 square feet of building space and 149 patient beds to its facility.

The patient rooms are now private and feature a bathroom with shower, fold-out bed and privacy curtains so families have the option to stay in-room with their child. Computer workspace, child broadcast center, playground, kitchen and laundry help support families during their stay.

Animas shutting down US operations for insulin pumps

On October 5, 2017, Johnson and Johnson and Animas pump company have confirmed they will shut down U.S. operations, and exit the insulin pump market. They have selected Medtronic as their partner-of-choice, and are offering their patients to switch to Medtronic insulin pumps. Current Animas users can continue using their current pump, and will be able to get their Animas pump supplies (reservoirs and infusion sets) from the vendor. 

New FIASP insulin approved for adults

On September 29, 2017, the FDA approved the new Novo Nordisk FIASP insulin for adults. This is a faster acting meal time insulin, that can be used instead of Humalog or Novolog. Check with your insurance company to determine whether or not this is a product on your formulary.

Freestyle Libre Flash CGM approved for adults

On September 27, 2017, the FDA approved the Freesyle Libre Flash Continuous Glucose Monitor (CGM) system in adults 18 years old and up. The sensor is factory calibrated, meaning it does not require any fingerstick calibrations. The sensor can be worn for up to 10 days, after a 12 hour warm up phase.

Transgender: Caring for kids making the transition

“As a child, Noah Wilson thought gender meant boy or girl, the end. But when they were both 14, Noah’s best friend, Rory, came out as nonbinary, a person who feels neither squarely male nor female.”

Hybrid closed-loop insulin delivery systems for Type 1 diabetes come of age

“The closed-loop system has completely changed our lives,” Sara said. “It took me a month to trust it, but now I can go to bed at 11 p.m. and wake up at 6:30 a.m. almost every night.”

This multidisciplinary clinic provides medical services for gender nonconforming youths and their families in one central location. The expert members of the Gender Clinic team consists of providers from pediatric endocrinology, adolescent medicine, pediatric urology and social services, supporting each child’s or adolescent’s gender identity. All our providers are members of the World Professional Association for Transgender Health (WPATH).

At Stanford Children’s Health, we bring experts in endocrinologyorthopedics, adolescent medicinegenetics and nephrology together to provide the best possible treatments for primary and secondary osteoporosis.

The pediatric endocrine bone health team at Stanford Children’s Health is nationally ranked in Diabetes & Endocrinology by U.S. News & World Report and treats children with endocrine disorders at our Welch Road clinic.

The mission of the Stanford Diabetes Research Center is to support basic and clinical research to discover, apply and translate science about diabetes and it complications, to improve health and wellness.
