"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 Migraine. 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. Dr. Auer is rated as an Experienced provider by MediFind in the treatment of Migraine. Her top areas of expertise are Familial Hypertension, Glucocorticoid-Remediable Aldosteronism, Hypertension, and Melorheostosis.

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. That's the most important thing to me. I spend a lot of time with the family, and I like to fish. We're big Eagles fans, and I have season tickets.

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 in focusing on prevention including health screenings, nutrition, and physical activity. My hope for my patients is that they feel as well as possible so that they can do the things that are most important to them. I enjoy seeing patients of all ages (from babies to seniors) and do several office-based procedures including skin biopsies, joint injections and Pap smears. I take care of a diverse population and believe that all patients deserve access to high quality healthcare, irrespective of their gender, race, ethnicity, religion, immigration status, gender identity or sexual orientation. | Why I entered medicine | I grew up with an older brother who was diagnosed with heart disease when he was 4, and I was inspired at an early age by his doctors’ care and compassion. I went into medicine to provide this same level of patient-centered care to others and strive to treat all of my patients as if they were family. Outside of my clinical practice, I am faculty in the Department of Family Medicine at LVHN and do research and teach medical students and residents. I am a better physician for all that I continue to learn through these activities and find great joy in both teaching the next generation of physicians and in conducting research aimed at identifying ways to improve health care. | Community involvement | I first lived in the Lehigh Valley during my college years at Lehigh University and was very excited to return to this vibrant community after completing medical school and residency.

I also serve on the Health Advisory Committee at Bradbury Sullivan LGBT Community Center. | Personal interests | I enjoy running and can often be found outside in the early hours of the day, wearing a head lamp and covered in reflectors. I figure you can never be too safe! I’m an avid home cook and own approximately 50 cookbooks.

Involving patients in their health care decisions helps them become more engaged and is essential for a strong patient-physician relationship. | Why I entered medicine | The allure of a healthcare profession began very early in my young adulthood after taking an anatomy course in high school. I had the opportunity to work with a variety of healthcare providers and specialties at a local hospital in Bucks County with furthered my interest. I loved the pace, the continuous quest for knowledge, as well as getting to know people in ways that others may never get to know. I immediately realized that this was the right profession for me. | Community involvement | I am actively involved in my church community.
