In the Spring of 2015, Dr. Kirschner headed to Williamsport to start her residency training in family medicine and she’s still here! She fell in love with the comradery within the residency, the scope of practice offered in family medicine locally, and the town of Williamsport. The training she received during residency allowed her to be comfortable teaching and practicing in all aspects of family medicine. She especially loves the obstetrical part of her practice where she can form relationships with moms, help them bring their children into the world, and then watch their children grow. She also enjoys working in teams focused on innovating and improving the residency. She became Associate Program Director in 2021 and has recently been named Program Director.

Outside of her passion for medicine, Dr. Kirschner enjoys spending time with her husband, daughters, and their two cats watching Philadelphia sports teams. She loves traveling to Cape May to spend time with extended family and enjoys cooking and baking.

Dr. Kaderli is passionate about advocating for the expansion of the scope of practice for family doctors nationwide, but especially in rural and underserved areas. He particularly enjoys the opportunity to practice inpatient medicine, obstetrics, and to teach a collection of motivated and talented residents.

She then transitioned to full-time faculty within the residency program and is now an Associate Medical Director. Dr. Anderson cares for patients of all ages, seeing patients in nursing homes and making home visits. Her favorite parts of “family doctoring” have been the time spent delivering babies, and then babies to those babies! She now enjoys caring for two, three, and four generations of families. She is especially passionate about women's health issues, inter-conception care, fourth trimester care, lifestyle medicine and geriatrics/end-of-life care, but truly enjoys all aspects of family medicine. When not at work, Dr. Anderson keeps very busy with her family. She has four grown children — one of whom also teaches in a family medicine residency program!

Dr. Boahene is a native of New York but feels right at home in Pennsylvania!

As a result, Dr. Boahene is a strong advocate for health equity and has research interests in eliminating health disparities and improving maternal-child health. Her philosophy is that family medicine is a “team sport” and its foundation requires excellent communication between patients, families, and clinical providers.

Medical School: Philadelphia College of Osteopathic Medicine
Residency: UPMC Williamsport Family Medicine Residency
Board Certification: American Board of Family Medicine

Dr. Boll is a native of Pennsylvania who joined the faculty after working in an underserved setting in eastern Tennessee for ten years. While practicing in a town of 1,500 people, Dr. Boll was able to care for a broad range of medical conditions from newborn and obstetric care to providing home visits and end-of-life care. He also was very involved in the management of a community health center and directed a community garden on his property in Tennessee. He brings this broad experience to the residency and can offer a different perspective in regards to providing medical care from this experience. Dr. Boll enjoys providing care to the entire family and has seen the value of developing meaningful relationships with his patients. Building these relationships enables patients to trust the medical care provided and for the physician to better tailor evidence-based care to the needs of the patient. Dr. Boll has worked with the Amish community in the north central Pa. region and provides home visits in this community.  He has taught extensively about rural medicine and rural medical issues such as snake bites, chronic pain, and addiction.

Residency: UPMC Williamsport Family Medicine Residency
Board Certification: American Board of Family Medicine

Dr. Josh Dearing is one of the newest assistant directors of the UPMC Williamsport Family Medicine Residency program. Dr. Dearing's journey to medicine was far from typical. Prior to becoming a doctor, he was a music teacher at Whitehall High School in the Lehigh Valley, where he used his versatile tenor voice to engage and inspire his students.

Dr. Dearing's passion for teaching and mentoring didn't end with his music career. It's what led him to medicine in the first place. After attending Geisinger Commonwealth School of Medicine, Dr. Dearing matched at the UPMC Williamsport Family Medicine Residency program, where he now serves as an assistant director. He's excited to bring his enthusiasm and dedication to teaching and training medical residents and students.

What's even more special about Dr. Dearing is that he was born at UPMC Williamsport, which makes his return as a physician all the more meaningful. Alongside his medical career, Dr. Dearing continues to perform as a classical tenor. Although he misses his days as a conductor, he's happy to let others take the lead. When he's not saving lives or singing, Dr. Dearing enjoys spending time with his wife and three young daughters.

Her passion for teaching grew from these experiences, and ultimately, she pursued a Faculty Development Fellowship in Pittsburgh. Through her fellowship, she obtained a Master of Science in Medical Education and further developed her skills both as a clinician and an educator. When looking for the next step in her career, the UPMC Williamsport Family Medicine Residency stood out as a way to practice full-spectrum care while leading the next group of family physicians.

Specialty: Behavioral Health
Education: Marywood University – Master of Social Work

Prior to joining the faculty at UPMC Williamsport Family Medicine Residency, Matt has been practicing psychotherapy for over 15 years. He has worked in various hospital systems, community mental health agencies, and private practices with clients facing a range of mental health concerns. His approach is nonjudgmental, experiential, warm, humorous, gentle, accepting, and empathetic. Matt encourages an environment that is supportive, open, and allows people to lean into their experiences. He strives to assist others to be comfortable and forthright about their thoughts and feelings, and to make important changes that move them towards an enriched, full, and meaningful life. He values helping others to develop a new relationship with themselves and their various emotional, psychological, and behavioral experiences. He allows a safe and supportive environment for others to feel heard, understood, and validated. Matt takes a holistic approach when working and considers the entirety of each patient’s interconnected experiences. His areas of interest include emotional disorders, family systems, primary behavioral health integration, and clinician resiliency and well-being.

When not working, Matt enjoys quality time with his son, meditation, exercising, learning as much as he can, and a solid nap (which can be both intentional or unintentional, but highly recommended after all that work and play).


Timothy M. Heilmann, MD, FAAFP – Associate Director

Timothy M. Heilmann, MD, FAAFP

Specialty: Family Medicine and Prenatal Care
Medical School: Jefferson Medical College
Residency: Forbes Health System
Board Certification: American Board of Family Medicine, American Board of Preventive Medicine - Clinical Informatics

Dr. Heilmann's initial practice experience was in a small town in northwestern Pennsylvania—in a setting so rural that there was even a hitching post behind the office for patients to tie their horses to. That rural setting provided an opportunity to practice the full spectrum of family medicine, from delivering babies (some at home) to fracture management, to making house calls, performing office surgery and visiting nursing homes. Dr. Heilmann brings all of those experiences and skills to the residency; many of his precepting sessions and mini-lectures begin with the words "Well, when I was back in private practice." Lest it be said that he is just an "old-fashioned country doctor," however, he also has a keen interest in evidence-based medicine and coordinates the residency's Journal Club to teach and explore EBM principles and practices in detail. Dr. Heilmann has also been very active in designing computer programs for teaching and for automating various residency functions, and he serves in the role of CMIO for the Susquehanna Health Medical Group.

A '79 graduate of the University of Notre Dame, Dr. Heilmann is a die-hard Fighting Irish fan (is there any other kind?); experienced residents know to tread lightly around him on Fall Mondays if the Irish have had a bad Saturday on the gridiron. Dr. Heilmann also puts the "family" in family medicine; he and his wife, Susie, are the proud parents of seven children. He is active in the Knights of Columbus; local community theatre; and a lector, cantor, and choir member at St. Ann Church. Dr. Heilmann has been very involved in organized medicine at the state and national level, having served for years on the Pennsylvania Academy of Family Physicians board of directors and as chair of the Residents and Student Affairs Committee. He is a past president of the Pennsylvania Academy of Family Physicians (PAFP).

Luan V. Pham, MD – Associate Director

Luan V. Pham, MD

Specialty: Family Medicine
Medical School: Penn State College of Medicine
Residency: UPMC Williamsport Family Medicine Residency
Board Certification: American Board of Family Medicine

Dr. Pham grew up in a suburb of Philadelphia and graduated in 2004 from Villanova University with a biology degree. He developed an interest in primary care during his time at Penn State Hershey Medical Center’s College of Medicine. After completing his family medicine residency at Williamsport in 2011, he decided to move back to central Pa. to work at a federally-qualified health center look-alike in Carlisle. Although he enjoyed his time there, he missed practicing inpatient medicine in an academic setting and interacting with residents and medical students. For these reasons, he enthusiastically accepted a faculty position at the Family Medicine Residency at UPMC Williamsport in 2014.

Dr. Pham’s professional interests include practice management, lifestyle and obesity medicine, and providing care for the underserved. He is the medical director of the Family Medicine Residency Center and oversees medical students rotating through our program. Besides spending quality time with his wife and four children, he also enjoys music, sports, carpentry and home renovation.

Sara Swain, DO – Assistant DirectorSara Swain, DO

Specialty: Family Medicine with Obstetrics
Medical School: Lake Erie College of Osteopathic Medicine
Residency: UPMC Williamsport Family Medicine Residency
Board Certification: American Osteopathic Board of Family Physicians

Dr. Swain grew up in the suburbs of Rochester, NY and graduated in 2007 from Rochester Institute of Technology. She graduated from Lake Erie College of Osteopathic Medicine in 2011 and completed her family medicine residency training in 2014 right here in Williamsport where she fell in love with both the program and community!

After graduation, she spent a short time practicing just north of Williamsport in a very small rural town, however found that she and her family were spending much of their free time back in the Williamsport area. Due to this, she opted to take a position with UPMC and spent 6 years here practicing outpatient family medicine.  During her time in outpatient practice, Dr. Swain worked part-time as a community preceptor for the UPMC Williamsport Family Medicine Residency and it felt like coming home again; when a full-time position became available, she jumped on the opportunity to return to the program as faculty!

Dr. Swain is also involved in the community outside of the residency program as the school physician for Williamsport Area School District, as well as keeping busy as the medical director for College Health Services at Penn College.  Her professional interests include women's health, obesity medicine, and working with neurodivergent individuals, as well as helping residents maintain a healthy work-life balance and helping to keep their passion for medicine alive.

Outside of medicine, she enjoys spending her free time with her husband and two children, their plethora of animals, and traveling as much as they can!

Enoch Tse, MD – Assistant Director

Enoch Tse, MD

Specialty: Family Medicine
Medical School: Lewis Katz School of Medicine at Temple University
Residency: UPMC Williamsport Family Medicine Residency
Board Certification: American Board of Family Medicine

Dr. Tse was born and raised in Hong Kong, but has called Pennsylvania home for more than half his life. His passion for broad-spectrum family medicine burgeoned in medical school, during which he spent his clinical years in Danville, PA. This was solidified during residency right here in Williamsport, where he had the privilege to provide continuity of care for patients of all ages, and across multiple settings — from the clinic to inpatient units, and from the nursery to nursing homes. He strongly believes that the cornerstone of primary care is family medicine, and feels very fortunate to serve as faculty in a residency that shares the same philosophy.

Dr. Tse's professional interests include practice management, global health equity, and evidence-informed medicine. His academic focus include clinical content/resource development for digital platforms and multimodal teaching.

Outside the walls of the hospital, Dr. Tse is an avid traveler and a fervent foodie. Don't be surprised if you find him jetting off to Madrid for the weekend, searching for the best beyran on the East Coast, or doing a deep dive into the surprisingly dynamic food scene of Williamsport.

"Ahhhh, Hawaii was nice, but Williamsport wins hands-down when it comes to Family Medicine education," states Dr. Verzella, who has been a full-time teacher since graduating from residency in 1985. He has been teaching here since 1989, after four years at Ft. Bragg, NC, as faculty in the Army Family Medicine Residency program there. He served as Program Director from May 2020 through June 2023, and will be retiring at the end of the 23-24 academic year after having helped over 200 residents become family physicians.
