Pediatric Associates of Whidbey Island has been providing medical and preventive care for children, teens, and families since 1979.

I came to Whidbey Island from the Navajo Nation (Northeast Arizona) in 2002.  I have been a pediatrician since 1994 and love the interaction with kids, even my own.  I feel that the pediatrician's role is to help parents raise children through authoritative, supportive guidance, not through coercion. During those times that I'm not working, you can usually find me walking with my wife of 20 years, trying to keep our lawn cut, and chasing deer away from my apple trees.  I also follow the trials and tribulations of the Boston Celtics, read a lot, and still dream about running away to join the circus.

I feel incredibly fortunate to have been able to finish up my 22 year career in the Navy at Naval Hospital Oak Harbor and now to join Pediatric Associates of Whidbey Island. I am excited to work with the awesome staff here at PAWI and getting to wear real clothes (although I will miss my comfy boots and multiple uniform pockets)! My favorite part of being a pediatrician are the relationships that develop between myself and the kids and their families and I look forward to those being longer and stronger without so many military moves. Outside of work I enjoy cooking; reading and you may see me out running with my dog. With my husband and two kids, I enjoy traveling (a nice perk of the Navy), watching movies, skiing and playing games. Our current favorites are 7 Wonders and Exploding Kittens—check them out!

I was born and raised in the Snohomish County area.  I moved to the south end of Whidbey Island in 1993 where I raised both of my children.  I had the great opportunity to do my pediatric rotation here at Pediatric Associates of Whidbey Island and was extremely excited to be offered a position as a Nurse Practitioner with this wonderful team. Prior to coming on board with PAWI, I worked at Providence Regional Medical Center as an acute care RN and still remain as an On-Call RN.  My passion for patient care stems from my belief that everyone deserves quality healthcare. I feel very fortunate to have the opportunity to work together with patients and their families to reach and maintain their healthcare goals. For fun I enjoy live music, crafts, home improvements projects, and relaxing in my backyard looking at the water, Cascade Mountains, and listening to the birds chirp in the trees. I also like to travel and I love the Caribbean and Kauai.

I was thrilled to join PAWI in 2019. As a Whidbey Island resident and healthcare provider, I had already developed a love for rural health and the families on this beautiful island. Prior to joining PAWI, I was honored to serve South Whidbey for six years as a Family Practice primary care provider in Clinton. During that time, I got to know Dr. Wagner and Nurse Teri through collaborating on mutual patients, ultimately trusting them with the care of my own children. It was a dream come true when the opportunity arose to join them and the rest of the PAWI team! Working with children has always been the bright spot of my day. Teaming up with families to promote healthy lifestyles, disease prevention, and empower my patients with health knowledge is my passion. I am honored to work with you and your children.

A lifelong resident of the Puget Sound region, my husband and I have been delighted to call South Whidbey home since 2012. We are parents to two fantastic daughters, an exuberant golden retriever, and have a small flock of somewhat-annoying chickens. When we can, traveling and learning about other cultures, history, and our planet with our daughters is our hobby of choice (kids fly free under 2!). Together we also love to hike, garden, snorkel, camp, and enjoy family walks on Whidbey. My main hobby though with young children is of course endless laundry and chopping food into tiny bite-sized pieces.

I'm thrilled to join PAWI and work in Pediatrics after working with "older kids" (aka, adults) for the past 7 years in Coupeville.  I grew up in Central Florida and came to Whidbey by way of Upstate NY and Philadelphia (college and medical training). Despite growing up in the land of white sandy beaches and sun, I love the outdoors, giant trees, gray skies, and sprinkling rains of the Pacific Northwest and try to get outside whenever I can.  I also love to read, dig in the dirt/garden, participate in musical theater at the Whidbey Playhouse, and help out where I can with the OHHS choir community. I believe wholeheartedly in creating therapeutic medical relationships founded on mutual respect and communication.

I’m thrilled to be rejoining Pediatric Associates. I was an employee here from 1989-1991. Since then, my wife Susan and I have run our own practice in Freeland at South Whidbey Pediatrics with the help of a loyal and able staff. We raised our 3 kids here (OHHS Grads), now health young adults.


I’ve sold the practice, joining PAWI. I love practicing Pediatrics and part time work feels great at this time. We’re expanding our services with additional providers in Freeland. My training has been in the care of acute and chronic illness and injury. I have learned the value of preventive care, now the main focus of our clinics. I have shared night and weekend call with my PAWI colleagues for over 30 years. I still enjoy caring for newborns at WhidbeyHealth.


My interests outside of work are wide so I’m an expert at none. I read a lot, technical, nonfiction and fiction. I enjoy growing things, running, kayaking, crabbing, etc. I love to win at poker, but I can handle losing.


Along the way I was and ER doc for 4 years in Oregon, spent 4 years in the Indian Health Service at Shiprock, NM and a year on staff at Harborview and Children’s Hospital in Seattle.

When my daughter enrolled at WWU, my husband and I fell in love with this corner of the world.  We bought our home on Guemes Island in 2016 but didn’t make the move permanent full-time until a few years later.  I’ve practiced pediatrics for over 20 years in the rural areas of eastern Washington and coastal northern California.  As a pediatrician, it’s been a great honor and privilege to be entrusted with the care of children.  Put simply, I love kids - newborns, infants, toddlers, all the way through the teenage years.  Each stage is so fun.  My family of humans, horses, dogs and cats are all happy to be here.  Outside of work I mostly muck stalls, feed horses, walk dogs and change cat litter.  I really cherish clear blue skies, night stars and the beautiful waters of the surrounding Salish Sea.

I am thrilled to be back home in Washington State, fulfilling my lifelong dream of caring for children on an island community outside of Seattle. I am returning to the Pacific Northwest after about 15 years away in order to attend Middlebury College in Vermont, medical school at Stony Brook University School of Medicine in New York, and complete my Pediatrics Residency at Children’s National Hospital in Washington DC. I provide general pediatric care for all children and adolescents, both when they are healthy and sick. I am also very excited to care for the Spanish speaking community on Whidbey Island. I bring with me to Whidbey my fiancé John, a love for developing relationships with the children and families I care for, as well as a deep appreciation for Frozen, Goodnight Moon, and every single song from Moana. We look forward to getting to know the community!


My favorite Winnie the Pooh quote is:

“When you wake up in the morning, Pooh,” said Piglet at last, “what’s the first thing you say to yourself?”

“What’s for breakfast?” said Pooh.

“What do you say, Piglet?”

“I say, I wonder what’s going to happen exciting today?” said Piglet.


Pooh nodded thoughtfully. It’s the same thing,” he said.
