Dr. Katelin Haley, DO

I truly feel that I have found my 'calling in life' as a primary care physician and love providing comprehensive and individualized primary care to our community. As a child, my family instilled a passion for reading and learning, with many of our dinner-table conversations involving stories of my parents work at the local Pennsylvania hospital laboratory. When my father first showed me how they made microscope slides to help diagnose a problem, as well as what a chocolate chip cookie looked like under a microscope, I knew I had to learn more about the human body and biology.  

I attended undergraduate at Marywood University, majoring in Biology with a minor in Religious Studies. I have a passion for service and travel, spending most of my spring break trips on international service trips to Guatemala, Tanzania, or domestic areas of need. During my college education, I gained clinical experience working as a nurses aide at the local nursing home as well as a plastic surgery office. These invaluable years provided me a greater appreciation for the stages of life, the value of hands-on care giving, and upmost importance of  time to listen to those we care for.  

I chose to pursue osteopathic medical education due to my desire to have "all the tools in my toolbox" to take care of patients, from pharmaceuticals to complementary and alternative treatments. I attended Lake Erie College of Osteopathic Medicine from 2009-2012, having been accepted into an accelerated primary care scholar pathway with the rigorous curriculum for the medical school education in 3 years of year-round education, rather than the traditional 4-year pathway. After medical school, I chose to attend a rural, unopposed family medicine residency at Meadville Medical Center, approximately 45 minutes south of Erie, PA. This allowed me to gain excellent experience caring for diverse conditions, as we were the only hospital between Erie and Pittsburgh. 


After our time in Northwestern PA, my family was ready to be closer to our extended family in central PA and for slightly warmer weather!  We moved to Seaford, DE and I joined Choptank Community Health, a community health center on the Eastern Shore of Maryland. At Choptank I enjoyed practicing clinically in Federalsburg and Denton, MD, with a focus on women's health procedures in Denton. From 2017 to 2019 I was honored to lead the clinicians at Choptank as the Chief Medical Officer and continue my clinical practice. 

In October 2019, our family was able to realize our long-time goal of relocating to Eastern Sussex County and my dream of joining a thriving solo private practice focused on high quality care with Dr Stanislav at Atlantic Adult & Pediatrics.  I'm honored to be a part of this community and the Atlantic Adult & Pediatrics family! 

My philosophy for my medical practice is that we are a team for your healthcare. I do not dictate what you must do, but work with you to find a plan of care that helps you meet your health goals. I value evidence based practice, and always welcome discussion of alternative therapies for your wellness. I enjoy the ability to offer minor office procedures and osteopathic manipulative treatments to my patients when appropriate.

Outside of the office, I enjoy spending time with my husband and daughters. We love the outdoors and enjoy kayaking together. The beach and water are our "happy place"! The girls and I love planting a small vegetable garden each year and seeing what our harvest will yield. My husband and I value our evening walks with our dog and enjoying live music together. Taking time to create resin ocean artwork is a way I've been able to bring my happy place home and explore my creative side.
