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 board 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.

Dr 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.

New Arrivals

Our newest fellows, Walter Zegarra and Holly Cooper, bonded during the department orientation July 6. They joined 46 pediatrics fellows across the department in team building activities like rock climbing and rope swings at the Arillaga Outdoor Education Recreation Center (AOERC) on campus. Welcome, Holly and Walter!

Disrupt Diabetes Mentors Patient-led Design Teams to Spark Innovation

This three-month long program places patients at the center of a design innovation process using patients as experts to solve unmet needs in the diabetes patient community. Preparation culminated on May 20, 2018  on Stanford campus with a day of brainstorming and pitching solutions for a chance to win funding and mentorship of  project proposals.

Maahs Presents on Novel Glucose Monitoring at ChildX and How the Stanford Diabetes Technology Team is Leading the Way Forward in Research

David Maahs, MD, PhD, Association Director of the Stanford Diabetes Research Center; Division Chief and Professor of Pediatrics (Endocrinology), spoke at ChildX conference at Stanford on April 13, 2018 on Next Generation Management of Chronic Illnesses: Technology for Real-Time Monitoring. Dr. Maahs addressed how novel approaches to monitoring and reporting blood glucose level are changing the way that care is delivered to children with diabetes.

Wilson Awarded Medical Staff Distinguished Service Award

Congratulations to Darrell Wilson, MD, Professor of Pediatrics (Endocrinology), on being awarded the Medical Staff Distinguished Service Award for his 40+ years of dedication to the care of our patients and their families. The Lucile Packard Children's Hospital staff presented Dr. Wilson with this honor on May 14, 2018 in grateful appreciation of his outstanding service and dedication.

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 endocrinology, orthopedics, adolescent medicine, genetics and nephrology together to provide the best possible treatments for pediatric osteoporosis or bone fragility. Most often, osteoporosis during childhood is caused by an underlying medical condition (called secondary osteoporosis) or a genetic disorder (such as osteogenesis imperfecta). We evaluate children to identify the cause, provide measures to improve overall bone health, and treat using drug (bisphosphonate) therapy if needed. 

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.
