Chief Residents

Hayley Baines, MD

In pediatrics we focus on developmental milestones, and for medical students, applying to residency is a big step! Congratulations on choosing pediatrics, and welcome to Phoenix Children's Hospital and Maricopa Medical Center, I think you have made an excellent choice. I had never visited Arizona before my residency interview. I was amazed by the beautiful hospital, the welcoming, down to earth residents and the wealth of educational opportunity PCH/MMC offered me. I am extremely proud of our resident-run hospitals and clinics and the extraordinary friendships and mentors I have found throughout my residency journey. I am confident I am prepared for the next step in my career, applying for fellowship in pediatric endocrinology. I am honored to be a chief to our wonderful residents, and I invite you to come visit our program. I quickly learned our program is a gem! Best of luck achieving this next milestone, hopefully we will see you soon!

Angela Ibragimov, MD

Hello and welcome! Although much of early childhood took place in Queens, New York, I consider myself an Arizona Native. It took a little getting used to, but like many Arizona transplants, I have fallen in love with Arizona's gorgeous sunsets, affordable cost of living, and more relaxed pace of life. My favorite thing about life in Arizona are the long sunny days - leaving work at the end of a long day and still catching enough sunshine to go for a hike or a swim in the pool is tough to beat! Aside from the geography, this program has had a place in my heart ever since I was a rotating third year medical student. Even during my first rotation, I quickly picked up on many unique features of this program that made me eager to be a part of it. I was impressed with how residents can effectively individualize their residency experience via the different tracks, resident longitudinal experience rotations, committees, and projects they choose to pursue. Additionally, there are many modalities through which residents are able actually impact the structure of the program. The multiple training sites offer residents a robust spectrum of medical contexts, pathologies, and diverse populations of varying healthcare needs. Having come full circle as a chief resident, I can honestly say this program has delivered on those expectations. Our program has been said to have a culture of "work hard, play hard" - we work hard and in turn receive rigorous training that prepares us well for any career endeavor, but we also support each other through this crazy adventure while taking care of our families, making long lasting friendships, and enjoying all that the southwest has to offer. I hope you come visit us soon!

Thank you so much for taking the time to check out our residency program in Phoenix! I am a native Texan and my interview in Phoenix was my first exposure to life in the desert. I felt truly at home after meeting the incredible residents and faculty that are the backbone of this program. Our pediatric residency program offers the incredible and unique opportunity to train at Arizona’s only quarternary pediatric center as well as a large public county center.  This balance of subspecialty and primary care was one of the main attractions to the program.  My wife and I couples matched to PCH/MMC and we both stayed as chiefs (see above) because we honestly feel that this large program has the “family feel” we were looking for.  After chief year I will be a pediatric cardiology fellow.  I hope you will come and visit, we look forward to meeting you soon.


Rebecca Wilkinson, MD

Hi there! Welcome to the PCH/MMC Pediatric Residency website. I am beyond thankful that my medical path led me out to Phoenix for my pediatric residency. It has been an incredible three years and I am glad to be staying out here for a chief year. I was immediately drawn to the beautiful city (who would have thought??), the warm and welcoming residents and the incredible diverse clinical opportunities. I was especially drawn to the second longitudinal clinic experience provided during your 2nd and 3rd years, as it was something I hadn’t seen offered at other programs. I loved the concept of a large children’s hospital as well as a county hospital, which has been an incredibly unique experience. I have been challenged by a high volume, fast-paced and clinical experience with medically complex patients over the past 3 years and developed an incredible clinic of continuity patients at the county hospital that I watched grow older over the years. I truly believe that I have received excellent training in inpatient, outpatient and subspecialty pediatrics.

Beyond the training that I received, Phoenix and PCH/MMC have become my home and our friends and co-residents have become our family. I said after graduation that these have been the hardest (and best) three years of my life. My husband and I (see below) moved from Texas and did not know a soul in Arizona, but we have been surrounded by an incredible support system and have gained lifelong friends. I hope that you find a residency program that is a perfect fit for you, as I have here, and I hope you come check us out!
