Philosophy of care | Listening is important. That's the most helpful to patients. You get the most insight into their personality. Communication is also important -- not only with the patient, but with the patient's family, and especially in the hospital or nursing home. Good communication goes a long way. I've been doing this for more than 10 years, and you build a relationship with your patients. I like to catch up, see how they're doing, ask about their family, vacations. | Why I entered medicine | My father was a doctor, and that had an impact on me when I was growing up. | Personal interests | My greatest passion in life is my family -- my wife and my two daughters.

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.

"Philosophy of care | My philosophy of care is patient-centered. I believe in a strong doctor and patient relationship that involves mutual respect, honesty, compassion and personal responsibility. I believe an essential part of ""doctoring"" is providing quality medical care in a caring atmosphere where every patient is heard and treated as a unique individual. | Why I entered medicine | Ever since I could remember I had always wanted to go into medicine. I am one of seven children. My mother was a nurse and she always encouraged me to enter the medical profession. She entered nursing school when I was 8 years old. I was brought up watching her study, listening to stories about patients and the hospital. My enthusiasm for medicine continued in high school and college; I loved the sciences. When it was time to fill out my application, I knew being a doctor would enable me to make a positive and meaningful difference in the lives of people when they need it most, and there are not many professions that give us that privilege. | Community involvement | I remain active in the community supporting my church, childrens schools and sports teams. I am also active in the American Heart Association's Lehigh Valley chapter. | Personal interests | As a mother of three beautiful children, wife of a wonderful cardiologist and a solo medical practitioner in internal medicine, personal interests are hard to fit in. My father purchased a home on the Jersey Shore in 1994, which allows me to enjoy the beach and precious time with my family. I also love to ski. I started skiing in medical school and make a yearly trek out West with my family and friends. As a physician, I am always reminding patients of the benefits of regular exercise, and I, too, try to remain physically active. In 2011, I completed the Lehigh Valley Marathon -- that was a very proud moment!". Dr. Persin is rated as an Experienced provider by MediFind in the treatment of Hypothyroidism. Her top areas of expertise are Vitamin D Deficiency, Sitosterolemia, High Cholesterol, and Hypertension.

Philosophy of care | I try to approach each patient interaction with an open mind and open ears. I listen to what patients are saying – and what they’re not saying – to get the complete story. My goal is to partner with patients and empower them to get involved in their care. | Why I entered medicine | Early on in school, I noticed I most enjoyed classes about health and the human body. As my medical training progressed, I discovered there’s so much more to being a physician than prescribing and diagnosing. It involves a unique mix of skills, including detective work and the ability to listen to and support patients. Practicing medicine is a very fulfilling career, ever-changing and always keeping me on my toes. I’m grateful for the opportunity to connect deeply with patients and help them live healthier lives. | Community involvement | I enjoy staying involved with medical education, including working with medical students and internal medicine residents. I also stay active as a volunteer at my children's school when time allows. | Personal interests | I have two awesome children who continue to keep me busy. I love time with my family and am naturally in my happy place at home, reading a book or cooking with my husband.

Philosophy of care | Every day, I try to make things better in the lives of others. I am a compassionate, caring human being.

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. Dr. Chu is rated as an Experienced provider by MediFind in the treatment of Hypothyroidism. Her top areas of expertise are Cellulitis, Empyema, Conjunctivitis (Pink Eye), and Necrosis.

Philosophy of care | Preventive medicine is the best medicine. People are living longer, healthier lives due to screening tests as well as advancements in treatment. It is a humbling experience to be a patient, and a physician needs to maintain that perspective. | Why I entered medicine | I entered medicine due to an interest in basis science and clinical care. Medicine provides a unique opportunity to treat an illness at both a molecular and cellular level. With recent advances in these areas, we are able to provide a higher level of care and improve the quality of life for our patients. Medicine is an innovative field and ever-changing. | Community involvement | American College of Physicians; community outreach to promote science programs in schools and student career development. | Personal interests | Alpacas and organic farming.
