Gina A. Friel, DNP, CRNP-PC
Gina is a Pediatric Nurse Practitioner at Annapolis Pediatrics, a large primary care pediatric practice in Annapolis, Maryland where she provides care to pediatric patients from birth through 21 years of age. Dr. Friel received her Doctor of Nursing Practice degree from Villanova University Fitzpatrick College of Nursing in December 2021 and is very excited to walk in the graduation ceremony in May 2022 along with her oldest son, Samuel, who will also graduate from Villanova University College of Engineering with a Bachelor of Science degree in Civil Engineering.
Dr. Friel has a particular interest in pediatric obesity and fostering healthy lifestyle habits in patients of all ages. The focus of her doctoral work centered on the Pediatric Obesity and Food Insecurity Paradox. Dr. Friel’s interest in childhood obesity is further expanded by her equally passionate focus on the impact the environment has on eating patterns that ensure food security, improve human health and wellbeing, diet quality and social equity. The intersection of environmental exposures, climate change challenges and the engagement of people, communities and diverse groups is an area of interest. This passion stems, in part, from living on the shores of the Chesapeake Bay, an experience that has further expanded her passion for understanding the vulnerabilities pediatric patients and families face related to climate change.
Erika Strickler, MD Candidate
Erika is a rising fourth-year medical student pursuing family medicine. While progressing through medical school in California, she came to realize that climate change is one of the most pertinent yet under-addressed factors affecting her patients' health. After finishing her clerkship year, Erika focused on ways to become more involved in climate health education. She joined the National Academy of Medicine's Health Professional Education and Communication working group, where she contributes to efforts to expand climate education in various health professional disciplines and advocate for advancements rooted in equity and justice. She is thrilled to further expand this work during her time at GCCHE, advancing her overall goal of being a physician that serves her patients by working towards systemic change.
In her free time, she enjoys snuggling with her rescue pup and life teammate Momo, dreaming up her annual trip to the Utah deserts with her best friend (and traveling in general), cooking Filipino food for friends and family, deepening her yoga practice, and as of late, obsessively watching The Sopranos. She stays up late at night pondering the role of the antihero and what her allegiance to Tony Soprano means.
