Philosophy of care | My philosophy centers on you, your personal needs and unique health journey. I believe in a collaborative approach, empowering patients with knowledge and being actively involved in treatment decisions. Whether managing chronic liver disease, guiding someone through a transplant process or offering preventive care, I create a compassionate and supportive environment where you feel heard and cared for. | Why I entered medicine | I chose a medical career to make a positive impact on people’s lives, especially in the realm of complex diseases like liver conditions, where treatment requires a balance of medical expertise and empathy. Liver disease, in particular, often affects individuals and their family in profound ways, and I find it incredibly rewarding to help patients navigate their care, from diagnosis to advanced treatments like a transplant. | Personal interests | I enjoy cooking and traveling, as well as time with family and close friends. I believe in maintaining a healthy lifestyle with proper eating and regular exercise. I'm also committed to finding a balance between work and personal life.

Philosophy of care | My approach as a transplant hepatologist is to treat the entire spectrum of liver disease, from early-stage diagnosis to advanced complications. My goal is to identify and address liver disease early to prevent progression to transplant whenever possible, because I believe if we can save livers, we can save lives. For patients whose disease is too advanced, we guide them and their families through the transplant process. | Why I entered medicine | I entered medicine to help people. That means using my skills and knowledge to make a real difference in patients' lives, especially those facing serious, complex illnesses. Being able to diagnose, treat and support patients through challenging conditions is a privilege and a responsibility. It’s about providing the right care, at the right time, and empowering patients to make the best decisions for their health. Whether it's helping manage symptoms, preventing disease progression or guiding a patient through a life-saving transplant, my purpose is to be there every step of the way, advocating for my patients and improving their quality of life. | Community involvement | I grew up in Pottsville, attended undergraduate school in Erie and went to medical school in Philadelphia. After completing all my subsequent training in Pittsburgh, I remained on faculty at the oldest and most established liver transplant program in the country. Now, I am excited to join the team leading the first liver transplant program in Allentown. This initiative will provide life-saving interventions to many who previously might not have had such an opportunity. It's a remarkable full-circle moment in my medical journey – one I couldn't pass up! | Personal interests | I have a passion for reading, researching and teaching about liver disease. Outside of my medical career, I love playing and watching sports – I'm a huge fan of the Steelers and Sixers. However, my favorite moments are spent with my family, especially my three children.

Philosophy of care | I believe in treating patients as equals and friends. When a patient visits, I want to make them comfortable when they share what’s happening with their health. I don’t like to lecture people, but I believe it’s important to educate patients about preventative medicine. It’s important to catch small issues before they become big problems. It's very enjoyable and very rewarding, particularly when I see patients in the hospital – and in the office – to know that what I am doing has an impact. I also like to find out what's going on in their lives in addition to the medical aspects – with their grandchildren, where they are going on vacation – just meeting people every day and getting to know them. | Why I entered medicine | Growing up, I played football and basketball in school, and I was always interested in how the body works. But my mom says it goes back ever further than that. She says I talked about being a doctor from the time I was 4 years old. I can’t imagine doing anything else – it’s who I am. | Community involvement | I spend time at Muhlenberg teaching interns, residents and medical students. | Personal interests | I'm caring, passionate, loyal and intense - intense in a good way. I care a lot about everything I do and everything that goes on around me. I love my family, and I spend as much time with them as possible. My wife and I have three children. And of course, we have our dog. Shes a German shorthair pointer and she’s definitely an important member of our family, too. I also spend a lot of time following sports – the St. Louis Cardinals baseball team and the Eagles. Dr. Wertz is rated as an Experienced provider by MediFind in the treatment of Enlarged Liver. His top areas of expertise are Familial Neurocardiogenic Syncope, Dementia, Glucocorticoid-Remediable Aldosteronism, and Familial Hypertension.

Philosophy of care | Every patient is different and unique. I like to work with patients as a partner, sitting face to face and talking together. My role is to present various evidence-based treatment options, based on scientific studies. I always encourage patients to ask questions, and I’m there to make sure they understand everything. I’m even happy to write it all down so they can take the information home and think about it. I can’t decide the best treatment for patients by myself, but I can provide options and guidance to help them choose the best care. | Why I entered medicine | My father has diabetes. When I was 15 he started going into a diabetic coma several times a year. The first time it happened, I was at home with my parents where we lived in Taiwan. My mom was crying, so I quickly called my older sister, who is a family doctor in the United States, and asked her what to do. With her help I took his blood pressure, heart rate and checked his blood sugar. I found that I liked caring for my dad and started thinking I’d like to do that for other people someday. But I didn’t really plan to go to medical school until my dad asked one day if I wanted to try. I did, and the rest is history. I’m now helping patients get well and stay healthy, just like I once did for my dad. | Community involvement | I volunteer regularly at my father-in-law’s church in New Jersey. I participate in rummage sales and other fundraisers that support the church community. My other passion is helping animals. I’ve always loved them since I was a child, and my heart cries whenever I see an animal being mistreated. I even thought about becoming a veterinarian before I became a human doctor. I now have two cats that I adopted from a rescue shelter, and I also send regular donations to the Society for the Prevention of Cruelty to Animals (SPCA). I help whenever I can. | Personal interests | I love spending time with my cats—they’re just like my son and daughter. My husband and I even have a small room in our house just for them, complete with a cat tree and toys. I also love traveling. When I was growing up, my mom took me abroad every vacation. I’ve been to Australia, New Zealand, Europe, Southeast Asia and many other places. I particularly like trying local foods and learning new languages. I speak fluent Chinese and English, plus I know a little Japanese, Korean and Tagalog (spoken in the Philippines). I love to learn new things, and I think seeing many different places and experiencing new cultures has made me a more open person and a better doctor.

Philosophy of care | I believe a physician should be compassionate, dedicated and work well on a team. I encourage my patients to be an active participant in their health care. | Why I entered medicine | My mother was diagnosed with aplastic anemia when I was 8 years old. From a young age, I became familiar with hospitals, doctors and nurses. Compassionate doctors explained my mother's illness. This experience gave me a better understanding of the medical profession, specifically the important role of the physician.

Philosophy of care | My principal aim is to treat all patients as I would want my family and friends to be treated: with dignity, respect and compassion. I want you to walk away from our first visit feeling seen and heard and knowing your experiences, thoughts and opinions regarding your care matter. I empower you and your caregivers with knowledge regarding your condition and how to navigate life with it. Living with liver disease can be incredibly difficult and overwhelming, so I am willing to walk with you every step of the way. | Why I entered medicine | Two reasons: my desire to care for others and my love for learning about the inner workings of the human body. I was drawn to the field of liver disease specifically because of the intellectual challenges inherent in caring for those with liver disease as well as the long-term relationships I am able to form with patients and their families. It is a career that challenges and humbles me on a daily basis, and I wouldn't have it any other way. | Personal interests | My family is my everything, and there is nothing more wonderful than spending time with them and watching my two children grow. Additionally, I love to garden, cook (though toddlers are the toughest food critics), make ice cream and ride my bike.
