Family Medicine Faculty

John J. Russell, M.D., Program Director, Chief of Family Medicine

John J. Russell, M.D.

“Risus sit Amet” – My oldest daughter was to come up with a family motto for Latin class. She chose “risus sit amet “, which means laughter must be shared. Whether it is in the office with patients, teaching and learning with residents, or sitting at home with my children, I believe that laughter is the currency that helps give life meaning and is the most direct way to connect with others for it shows that we appreciate life, with all its complexities, inconsistencies and joys.

There is the old expression that medicine is “an art”. The question is which type of art is Family Medicine most like? In thinking about this question, I would say that family medicine is most like Jazz. When you watch a great jazz artist perform several nights in a row you hear many of the same songs each night. In the spirit of jazz though, they do not sound exactly the same. The “melody” of Family Medicine is Evidence Based Medicine. The tempo is defined by the needs of the patient. The improvisation that integrates the melody, tempo, and an indefinable quality of spirit is what makes the artist an artist, and what makes the medicine that each of us practices as unique as we are and allows us to change our approach based on the individual needs of each patient.

What background influences my art? My art of medicine is informed and influenced by the hard-working values of my family who taught me that anything worth doing is worth doing well. My art is informed by a deep sensitivity to people and enhanced by growing up just miles from the hospital, understanding the rhythms and nuances of the people of our community. I also bring the joy and wonder of someone who loves and is constantly amazed by the beauty, courage, energy, and devotion that our patients show us daily in how they handle their lives through health and disease."

Mathew M. Clark, M.D., M.A.

"Work is love made visible.” – Kahlil Gibran


"I’m privileged to have been a physician and teacher for almost 40 years. Although our work can be stressful and tiring—especially during medical school and residency—at its best it can also be deeply meaningful and rewarding. I enjoy being part of our residents’ lives and learning, as they morph from recently-graduated students to competent attending physicians."

Dr. Clark has a B.A from The Evergreen State College, an M.A. in psychology from the University of Santa Monica, and an M.D. from Yale University School of Medicine. He completed his Family Medicine residency at Kaiser Foundation Hospital in Los Angeles. Prior to joining the Family Medicine faculty at Abington in 1990, he worked in a community health center and an emergency department in Philadelphia. He has also spent extended periods of time doing medical service in Thailand and Mexico, and regularly performs forensic medical evaluations for refugees seeking political asylum. Dr. Clark has a Certificate of Added Qualification in Geriatrics. He regularly speaks and publishes for a national Family Medicine audience. Areas of interest include geriatrics, procedural medicine, and physician well-being.

Amy L. Clouse, M.D., Associate Director

Amy L. Clouse, M.D.

"When I first walk in the room to see a patient, the first thing I notice is if they look happy or sad. I do this because a person’s mood sets the tone for the visit and likely their approach to their healthcare and probably their life. What has always intrigued me is who someone is and not just what their disease is, because who they are influences more than anything else how they do with whatever it is they are seeing me for. I feel the same way about teaching: who someone is, their orientation toward learning, how they learn, it all helps me to understand how to best help them to grow both as a doctor and as a person."


After earning her B.A. in Biological Sciences with a Minor in Women's Studies from Northwestern University, Dr. Clouse attended the Medical College of Pennsylvania where she received her M.D. degree with Honors. She started post-graduate training in Obstetrics/Gynecology at the Cooper Hospital/University Medical Center and then changed to Family Medicine when she realized that her professional interests in women's health would be better served by this specialty. Dr. Clouse completed her residency training at the West Jersey Family Practice Residency Program in 1998 as Chief Resident.

Dr. Clouse brings strong skills, experience and enthusiasm for women's health care to our program including obstetrics, menopausal issues, and gynecologic procedures such as colposcopy and endometrial biopsies. She also holds a Certificate for Added Qualifications in Adolescent Medicine and has a special interest in eating disorders and other adolescent issues such as contraception and sexually transmitted diseases.

Dr. Clouse speaks nationally on women's health topics and has multiple publications to her credit. She has recently co-edited a women's health book for primary care providers and contributed two chapters to that book. She considers herself a “foodie”, always enjoys a good book and a great glass of wine and can often be found training for a local running race.

Susan Fidler, M.D.

“Shoshin” is a concept derived from Zen Buddhism meaning “with a beginner’s heart, mind and spirit.”

These are words that resonate with me and represent why I love working with our resident physicians here at Abington Family Medicine. I feel privileged to have the opportunity to help educate and guide our new physicians as they learn new skills and face new challenges in this continually changing era of healthcare. My time with our residents and students reminds me to approach the problems and issues my own patients face with enthusiasm and a “beginner’s heart”.


Dr. Fidler is a graduate of Villanova University and The Pennsylvania State University College of Medicine. She completed her Family Medicine residency at UPMC St. Margaret Hospital in Pittsburgh. She holds a Certificate of Added Qualifications in Sports Medicine and has special interests in the treatment of Opioid Use Disorder in Primary Care and outpatient Point of Care Ultrasound.

Gerald J. Hansen, III, M.D., Associate Director

Gerald J. Hansen, III, M.D.

"One of my favorite patients was a wonderfully wise and delightful Ukrainian great grandmother. She lived until almost her 102 birthday in a residential apartment in one of the retirement communities we provide care. In spite of complex medical problems such as inflammatory bowel disease, Parkinsonism and aortic stenosis, her mental faculties were quite sharp. She loved it when I would bring by medical students and our residents to sit and speak with her. As well as teaching these folks medicine in Geriatrics, she would impart some of the wisdom gained from a century of experience. Her favorite nugget was “after everything is said and done, the only thing that matters is love.”

The nurses at her facility informed me that she was refusing to eat or take her medications and that she wanted to die. I sat down and spoke with her to make sure that pain, depression or any reversible condition was not behind her decision. She assured me that was not the case and that she was happy that her time had come. With tears in my eyes, I told her I would miss her and that it was my privilege to know and care for her. She looked at me and asked with her Ukrainian accent, “May I say something doctor?” “Certainly," I replied. She grabbed my hand tenderly and said, “You have been a wonderful friend.”

The richness of patient relationships and the gifts of the opportunities to facilitate learning by students and residents are what make being a family physician and teacher so special to me. Our program has many stories such as this and we welcome you to become a part of them."


Dr. Hansen is a graduate of Trinity College and the University of Connecticut School of Medicine. He completed his family medicine training at Chestnut Hill Hospital in Philadelphia and post residency training in family therapy at the Child Guidance Clinic of Philadelphia. Dr. Hansen has over 20 years of experience in teaching residents and medical students and has been director of the program for nine years. In addition to his Board certifications in family medicine and pain management, he has a certificate of added qualification in geriatrics and an affiliate certification in marriage and family therapy. Dr. Hansen has served as a hospice medical director for 12 years and lectured regionally and nationally on pain management and end of life care issues. As Chairman of Abington Hospital's Physicians' Health Assistance Committee, and member of the Board of Directors of the Delaware Valley Physicians' Aid Association, Dr. Hansen has demonstrated a strong commitment to physician health and well-being that extends to the residents of our program. His other professional interests include addictions medicine, obesity, cross culture medicine and primary care counseling.

Tracey Roesing, M.D., Associate Director

Tracey Roesing, M.D.“Inside every block of marble or stone lies a beautiful statue; one only needs to uncover the excess material to reveal the work of art within.” – Michelangelo


As I have worked with patients, students and residents over the years it has become apparent to me that each has something amazing to offer, if we take the time and develop the interest and ability to see and work with the people around us. After ten years in private practice, I decided to move to an academic medical career. The energy and excitement for continued learning, in addition to the high level of care that is provided to the community, were the main things that influenced me to seek a faculty position at Abington Family Medicine.

Dr. Roesing completed her undergraduate education at James Madison University, and then went on to complete medical school at MCP/Hahnemann University in 2000. She then spent her three-year Family Medicine residency at Abington Memorial Hospital, graduating in 2003. While in private practice, Dr. Roesing returned to the Abington Family Medicine residency program as a part-time community physician preceptor. In 2014, Dr Roesing decided to assume her present full time faculty role at the residency program. Dr. Roesing serves as the family medicine clerkship site director for third year medical students from Jefferson, Drexel and PCOM. Additionally, she is a certified wound care physician and spends time working at the Warminster Wound Healing Center at Abington Jefferson Health.

Outside of the office, Dr. Roesing has quite a busy family life with her husband, four children and two dogs. A former collegiate lacrosse player and current sports fan, most of her family activities revolve around sports and other active, outdoor activities.

Meera Shah, D.O., M.B.A., Osteopathic Program Director

Meera Shah, D.O., M.B.A.“To be human, is to be grateful” – inspired by Rev. Pandurang Shastri Athavale

"To cultivate this everlasting, progressive, and intense sense of gratitude has been an important goal in my life. I am grateful to so many who have helped me be the person I am today. I owe it to my hard-working parents, who uprooted everything and started over to offer me better education and opportunity, and to my husband and three beautiful children who continually support me and my passion for my profession. I am also grateful for my many teachers and mentors and for the opportunity to be able to be a small part of the educational journey of family medicine residents

Any object visually exists only because it knows to reflect the light that has shined upon it. The realization of how blessed I am has taught me to reflect that light of love and warmth unto others, particularly my patients. As influential teachers in my life, my patients continue to inspire me every day to become not only a better physician, but also a better human being. It is what makes me proud to be a part of the Family Medicine community at Abington – Jefferson Health."


Dr. Shah is a graduate of University of Maryland, Baltimore County where she also obtained a Masters in Chemistry. She received her medical training at Philadelphia College of Osteopathic Medicine while working on her MBA in healthcare administration at St. Joseph’s University. She is a product of our proud Family Medicine Residency program and is an Osteopathic Physician who is proficient in Osteopathic Manipulative Medicine. Dr. Shah brought her enthusiasm and zeal to Abington Family Medicine in 2011 after completing her fellowship in Geriatric Medicine at Abington Memorial Hospital. Currently, she is part time faculty with Abington Family Medicine, dedicated to serving our local nursing homes, and taking part in mentoring our residents in our Family Medicine.

Dr. Shah is a proud mother of three, and when not immersed in the joys of motherhood also takes deep interest in studying philosophy and scriptures of her Indian culture.

Neil S. Skolnik, M.D., Associate Director

Neil S. Skolnik, M.D."My favorite story is that of an old Yiddish tale where one of the “wise men” of Chelm says to his wife, “If I were the czar, I would be even richer than the czar.” His wife, puzzled as usual by his remarks says, “How can that be?” To which the wise man replies, “If I were the czar, I would do a little teaching on the side.” I like this story because it conveys a fundamental truth: when you love teaching, you teach. That is why I, and all the faculty of our program are here at Abington Family Medicine."

“Be kind, for everyone you meet is fighting a hard battle.” – Socrates

"For any students of Greek philosophy, I feel that the life of the goddess Persephone best personifies my life: rather than splitting my time between Demeter and Hades, my working career is split between working for the residency and working for a private practice. I find that my duality in career not only works for me but allows me to thrive. In addition to educating residents and students, I am able to relate well to soon-to-graduate residents and recent graduates as they adjust to post-residency life."

Dr. Callahan graduated from the University of Scranton, studying biology with minors in both history and philosophy. He then proceeded to attend the Philadelphia College of Osteopathic Medicine where he attained a graduate certificate in Biomedical Studies, and then a Doctorate of Osteopathic Medicine, graduating in 2012. In 2015, Dr. Callahan graduated in from the Abington Family Medicine Residency Program. Dr. Callahan currently works both at a private practice in the Abington-Jefferson network, as well as for the Abington Family Medicine Residency Program. Dr. Callahan maintains an active interest in LGBT healthcare and lifestyle management for health maintenance. He also takes part in the residency’s Osteopathic Manipulative Medicine curriculum and works actively with the network to address physician burnout.
