Philosophy of care | In my area we’re dealing with people who are frightened. I’m trying to help patients deal with all of the information they’ve been hearing, and I’m trying to dispel all of the myths. It’s a matter of education and mutual trust. I’m there to do whatever I can do for them, even if it’s just a matter of easing their pain. | Also, I am a member of the thoracic cancer multidisciplinary consultation team. Together we review your diagnostic information and give you a written opinion reflecting the scope of your condition and recommendations for your best course of care. | Why I entered medicine | Medicine was not my first choice. I wanted to be first oboe in the New York Philharmonic. I have a love of biochemistry and science, and I like people. One day, I just decided I wanted to be a doctor. I wouldn’t change it for anything in the world. | Community involvement | I’m part of the National Cancer Institute’s community cancer program. Our goal is to be able to give the same care and treatment to everyone, whether they have health insurance or not. | Personal interests | I still play the oboe and will always have a love of music. I’m an avid cyclist, and I enjoy skiing. Dr. Friedman is rated as an Advanced provider by MediFind in the treatment of Mesothelioma.

"Philosophy of care | Each of my patients is special and I try my best to treat each person as a whole.  I believe in merging the most advanced technological surgical techniques with a holistic approach. | Also, I am a member of the thoracic cancer multidisciplinary consultation team. Together we review your diagnostic information and give you a written opinion reflecting the scope of your condition and recommendations for your best course of care. | Why I entered medicine | I believe medicine and surgery is a true life's calling. To be able to dedicate oneself in treating others is truly a privilege and honor. Surgery allows me to focus on the ""moment"" that is almost a spiritual experience. | Community involvement | While I was practicing in Philadelphia, I started a community 10k and 5k run in Washington Crossing to beat lung cancer. Not only to raise for money for lung cancer research but also to educate the public about lung cancer screening. As a thoracic surgeon, my role extends beyond operating. I potentially can save more – even lives – through education. | Personal interests | I enjoy martial arts, meditation, hiking, camping and fishing. | Image | Lehigh Valley Hospital is ranked 42th for pulmonology and lung surgery on the 2025-2026 U.S. News & World Report Best Hospitals list. | ".

Philosophy of care | Effective medical care begins with a deep understanding of each patient’s circumstances and needs. The physician-patient relationship is foundational and must be a two-way dialogue built on trust and respect. I prioritize learning what truly matters to you and your family. I offer treatment recommendations and options that align with your values, preferences and goals. While my clinical focus is on blood disorders and blood cancers, listening carefully and tailoring care to patients is the heart of everything I do. I provide guidance and recommendations, but the decisions ultimately belong to you, the patient. I strongly believe in a team-based approach, where collaboration and communication yield the best outcomes. | Why I entered medicine | When I started college, medicine was the farthest thing from my mind; I was an economics major and took the MCAT on a whim. To my surprise, I scored far better than expected for someone without a science background, and that led me to medical school. Looking back, I can’t imagine doing anything else. Medicine – and caring for patients – has become my true passion. My path into the field was unconventional but led me exactly where I was meant to be. Practicing hematology and oncology isn’t just a career for me – it’s the only thing I can see myself doing. | Community involvement | As a part of cancer center leadership, I participate in local events and charities for patients with cancer and blood diseases, including speaking to the leukemia/lymphoma society. I am particularly fond of events centered around running for cancer charities. | Personal interests | Running is a personal passion of mine – second only to medicine and my family.
