Megan Aylor
Megan is a native of the Pacific Northwest and completed medical school at OHSU. She ventured to the east coast for residency training, followed by a chief year, at the Children’s Hospital of Philadelphia. She was delighted to return to OHSU as a pediatric hospitalist and medical educator. Megan has an interest in patient safety, team communication, and quality improvement, and worked for many years as an APD and medical director before taking on the PD role. Megan loves being a pediatric residency program director, as she finds working with pediatric trainees and being part of their professional development rewarding beyond measure. 

When not at work, Megan loves dancing, hiking the beautiful Pacific Northwest trails, traveling, eating good food, and playing games with her husband and two daughters.

Associate Program Directors

Sarah Green
Sarah is an Oregon native and a graduate of OHSU medical school and our beloved residency program. She spent a year as chief before joining the pediatric hospitalists and becoming an associate program director for the Pediatric Residency Program.  

Sarah loves the teamwork that comes with taking care of patients with students and residents, and is committed to making all feel included. She has been known to inadvertently delay rounds while socializing with all the friendly faces on the wards and does her best to teach while taking thoughtful care of children and their families. Her role as associate program director is a wonderful complement, allowing her to have input on resident education as well as the opportunity to support and coach an incredible group of smart, kind, hard-working humans. She is the chair of the Residency Competency Committee, which works to ensure that every resident is successful. She is grateful for her feisty and dedicated colleagues and can assure you there has never been a boring team meeting! 

At home, Sarah has a husband, two step-daughters, a son, and a part-time bunny. She does her best to make sure everyone has at least been fed and, if she’s lucky, gets them all outside. She loves being a mom to her three kids and is grateful for all the adventures and chaos that ensues.

David Rozansky
David (or “DJR” as he is known around Doernbecher) is a faculty member in pediatric nephrology, researching sodium transport mechanisms and clinically concentrating on renal tubular conditions, hypertension, and dialysis. He has been a faculty member at OHSU since 2001, including serving as an associate program director for the residency program since 2008. DJR educationally enjoys curriculum development for interactive conferences and subspecialty rotations. He also teaches trainees at all levels within the School of Medicine. 

DJR grew up in San Diego, receiving most of his undergraduate and medical school training in California before doing his pediatric residency in Chicago and nephrology fellowship in San Francisco. He and his wife Elana raised their two sons in the Portland area and recently became grandparents. DJR loves sports, his sports teams, reading history, and outdoor adventures, especially throughout the Pacific Northwest.

Melissa Weddle
Melissa has been faculty at OHSU since 2010, serving as continuity clinic director and associate pediatric program director. She is an East Coast transplant who grew up in Virginia and has practiced in Maryland, Ohio, Wisconsin, and Washington prior to coming to OHSU. She has worked in varied primary care settings, including federally qualified health centers, private practice, and an academic clinic. At OHSU, Melissa has embraced the opportunities for scholarship and education in ethics, compassionate communication, and adolescent health. Opportunities to teach both within and outside the clinical setting, continually learn from those around her, and listen to residents and colleagues to figure out how to make our program ever better are what make her job rewarding.  

Melissa has a writer-scientist-teacher husband and two grown-up children who live too far away. Outside of medicine, she loves movies with subtitles, food with spice, and hikes with views. She is a dog person. And a cat person.

Program Administrators

Jodi Leonard, Residency Program Education Manager
Jodi has dedicated over 20 years to the educational mission of the OHSU Department of Pediatrics and the institution’s graduate medical education community, receiving the ultimate honor of the ACGME Debra L. Dooley GME Program Coordinator Excellence Award in 2021. As the residency education manager, she has found the perfect home for her “mothering” heart. She works to keep the program on track with proactive organization, creative forward-thinking, open collaboration on all levels and endless optimism. She is honored to work alongside such a supportive and compassionate leadership team, and is continually inspired by the residents she works with.  

When she is not organizing schedules and recruitment, she enjoys time with her wonderfully silly family – usually outdoors hiking or camping. She is also an avid sports-mom and has logged many hours cheering from the sidelines!

Michael Grubbs, Pediatric Residency Program Technician
Mike was born and raised in Seattle, Washington, and moved to Portland for college, where he earned a degree in theology. After graduation, he got married and moved across the country to live in Big Apple (NYC). It was there that he started working in GME, as the fellowship coordinator for the Gastroenterology Fellowship Program at the Mount Sinai Beth Israel Medical Center. After eight years of long daily commuting and having two wonderful children, Mike and his family moved back to the great Pacific Northwest where the air is fresh and clean. In 2015, he was hired at OHSU as the program coordinator for the Pediatric Residency Program. It is here that he found true happiness working with all the wonderful residents and caring program staff. In his current role as residency program technician, Mike enjoys taking care of the day-to-day operations of the program, and always makes sure the resident lounge is supplied with tasty snacks.  

Mike now live across the river in Vancouver, Washington, with his wife Julie, son Nolan (age 10) and daughter Lily (age 6). Outside of work, he loves spending time with his children in the outdoors, making fresh sourdough bread with his wife, and raising chickens (he has recently started bartering eggs for coffee beans!!).

Chief Residents

Andrew Arndt

Andrew grew up in Wenatchee, Washington – famously self-declared “the apple capitol of the world”. He studied chemistry at Washington State University (Go Cougs!) prior to making his way down to Portland for medical school. Here, he met his wife Allie, a physical therapist and they discovered that 4 years in Portland was simply not enough. Fortunately, he was able to stay at OHSU for pediatrics residency, where he joined a family of loving and caring residents. By the end of residency, one more member was added to this large family, Allie and Andrew’s son Paxton “PJ”. Andrew wasn’t quite ready to leave the community built in this program, and wished to stay on as a chief resident. He’s excited to fold in to an amazing group of leadership in pursuit of improving training for all residents through nurturing personal connection and invigorating resident education.

Outside the hospital, their family loves to spend time together learning how to be parents (no amount of training prepares you for this) and dancing in the kitchen. They love to get outside when they can, especially if it includes sports or mountains – and Andrew is always looking for willing participants for his intramural teams. If not outside, you may find him reading the latest YA book, watching movies or playing any number of board games.

Mackenzie Nesbit Deane

Mackenzie is a born and raised Oregonian. She has loved growing up and exploring the Pacific Northwest and has been fortunate to attend medical school and residency at OHSU. Early on, she developed a passion for education and found pediatrics to be a perfect blend of patient care and teaching. Throughout medical school, she focused on quality improvement within our Gender Clinic. As she progressed through residency, her interests evolved to focus more on student and resident education in both inpatient and outpatient settings. Staying on as a chief has been a dream since starting residency and she is excited to get to spend the year working with amazing people across the board, gaining leadership experience, and helping to grow our outpatient general pediatrics experience.

Outside of work, Mackenzie enjoys filling her cup with lots of family and friend time. Her partner, Ryan, is finishing his residency, so they have spent the last three years learning to balance training and outside of work life. When robust with energy they love biking, exploring parks, and finding fun concerts to attend. On quieter nights, they enjoy playing cribbage, working on the NYT crossword, and settling down with a good show or book.

Tate Correll

Tate was born and raised in the beautiful state of Colorado. She completed her undergraduate degree in Biological Sciences and took four magical years off after she graduated from Colorado State University. During that time, she worked with Patch Adams, helped create a free MCAT study program for students with financial hardship, joined the Peace Corps as an HIV/AIDS volunteer in Botswana, and completed her 200-hour yoga teacher training in India. After years away from home, she was thrilled to stay in Colorado for medical school at Rocky Vista University. Inspired by her Peace Corps experience, she chose to go to an osteopathic school to learn manipulation techniques to have skills at her disposal to treat patients, regardless of the available resources. During medical school, she came to OHSU as a visiting sub-I student and fell in love with the people, the culture, and the beauty of the Pacific Northwest.

Tate had her first child during residency and loves to mentor other residents who journey through residency combined with parenthood. She spends all her free time with her husband, 2-year-old son, cat (adopted and brought home from Botswana), and new puppy. Her family enjoys all things outdoors, including camping, paddle boarding, hiking, yoga, skiing. Tate will also be completing her 95-hour Children’s Yoga Teacher Training this fall and is looking forward to using those skills to give back to her community. She is greatly looking forward to chief year and having the time to pour love and energy into a program that helped her grow so much.
