Please join us in welcoming Katrina Allen, PA-C, to our team!
Katrina joins our office as part of our growing team, bringing valuable experience in urgent care and emergency medicine.

She earned her Bachelor of Science in Exercise Science from Sacred Heart University and later completed her Master’s in Physician Assistant Studies at Franklin Pierce University.
Katrina is passionate about helping families build lifelong healthy habits and believes healthcare should support physical, emotional, and mental wellbeing. Her experience in acute care inspired her to transition into primary care pediatrics, where she can build lasting relationships with children and families while providing compassionate, comprehensive care.

When asked what inspires her as a provider, Katrina shared:
“Seeing patients grow confident in their own health inspires me to continue to provide good care and find new ways to help patients become the best versions of themselves. When a patient begins to feel well and takes charge of their own healthcare in a safe way, they begin to help others do the same. I feel this is the best way to help our community as a whole.”

One of Katrina’s favorite clinical memories came while working in urgent care, when a child arrived with symptoms that seemed subtle at first but ultimately led to the recognition of Diabetic Ketoacidosis (DKA) and a new diagnosis of Type 1 Diabetes. Thanks to quick intervention and teamwork, the child received lifesaving care. A few days later, when the child was discharged from the hospital, the whole family came back to thank Katrina and her team for recognizing the signs and saving his life. She shared, “I’m grateful for the team I worked with in that clinic and glad Mom brought him in that day!”
Outside of work, Katrina enjoys spending time on the lake with her husband and three children, running, and helping with her family’s greenhouse business.

We are so excited for our patients and families to meet her — welcome, Katrina!

Please join us in welcoming Dr. Miller who will be joining our team this August!

We are thrilled to announce the addition of Dr. Miller, a board-certified Pediatrician dedicated to providing compassionate, evidence-based care for children from infancy through young adulthood (0–21 years old).

Dr. Miller believes in building strong relationships with families and partnering with parents to support each child’s physical, emotional, and developmental well-being. Known for her approachable and caring style, she strives to create a welcoming environment where children feel comfortable and parents feel heard.

After earning her degree in Osteopathic Medicine from Kansas City University of Medicine and Biosciences in 2011, Dr. Miller completed her Pediatric Residency in 2014 through the National Capital Consortium Pediatrics Residency Program at Walter Reed Bethesda National Military Medical Center. She then served in the Navy as a Pediatrician at Fort Bragg’s Womack Army Medical Center before returning home to New Hampshire in 2017. For the past 9 years, she has cared for local families at Southern New Hampshire Medical Center with Foundation Medical Partners.

When asked why she chose Pediatrics, Dr. Miller shared:
“From a young age, my goal was to become a physician. My older sister and I were both born prematurely, and I was inspired early on by her passion for helping others. My mother was an elementary school teacher for over 30 years, which inspired my love for caring for children, while my family’s involvement in ski patrol sparked my interest in medicine. During medical school, I learned that Pediatrics is often called ‘Happy Medicine,’ and that joy is something I truly experience every day.”

We are so excited to have Dr. Miller join our team! If you have any questions or would like to establish care with her- please give our office a call, 603-216-0400.
