Family MedicineLanguages:
EnglishI was privileged to join the team of family physicians at St. Luke's Walbert Avenue Family Medical Center in Allentown in 2015, where I get to care for children and adults of all ages. My practice includes preventive care, acute concerns of all kinds, geriatrics and numerous office-based procedures. I love taking the time to get to know my patients and their families, and we take pride in providing the same positive, honest and thorough care to all our patients.
I am proud to say that I was born and raised in the Lehigh Valley, a graduate of William Allen High School, Lehigh University, and Temple University School of Medicine in Philadelphia. I completed my residency at St. Luke's University Hospital in Bethlehem, and am board-certified in Family Medicine. My wife and I live in the Allentown area, and we attend St. Nicholas Greek Orthodox Cathedral in Bethlehem, where I have been a chanter for over 17 years. In addition to music, some of our other interests include travel, gardening and cooking.

“Dr. Tatalias is wonderful. I am so lucky to have a physician who cares and takes time to listen. If I ever have issues or get upset, it usually is not because of Dr. Tatalias or due to anything he does. I wish all of my specialists were like him as well, it would make my life so much easier. I can always tell he is concerned and puts my own best interests first. My mother, father and brother all see Dr. Nick and there is good reason. I will always stick with St. Luke's because of him. I don't trust anyone else.”
