Please note that Dr. Lim, our founding dermatologist, retired in August 2025. Dr. Lim is native to western Pennsylvania, having been raised in Beaver Falls. He attended Allegheny College where he received his Bachelor of Science (BS) degree in Chemistry in 1982. Following college, he went to the Philadelphia College of Osteopathic Medicine (PCOM) where he received his Doctor of Osteopathic Medicine (DO) degree in 1986. He completed his internship in Philadelphia in addition to three years of specialized training in dermatology at the PCOM-affiliated Dermatology Center. Upon passing his National Board Examination, Dr. Lim became Board Certified in Dermatology by the American Osteopathic Board of Dermatology. He is a Fellow of the American Osteopathic College of Dermatology, Fellow of the American Academy of Dermatology and a member of the Erie County Medical Society, Pennsylvania Medical Society, American Osteopathic College of Dermatology, Pennsylvania Academy of Dermatology & Dermatologic Surgery and the American Society of Dermatologic Surgery. Following his dermatology training in Philadelphia, he came to Erie, the home-town of his wife, Jessica, to open his solo private practice in 1990. He has enjoyed the autonomy of private practice and has had the honor and privilege of building his practice from scratch. He attributes his success of his busy practice to his genuine love of dermatology, the positive feedback of his patients, and the loving support of his family and staff that allow him to do what he does best. Dr. Lim has volunteered his time educating medical students, interns, and residents since 1990. He is honored to have inspired many to have pursued careers in dermatology, a competitive yet under-served field. He is particularly proud to have his son, Geoffrey Lim, MD, follow his career path to become a dermatologist and further specialize as a Mohs surgeon. He is equally proud to have his daughter, Lauren Senita, CRNP, become a Certified Registered Nurse Practitioner in Dermatology and join him in his private practice. Dr. Lim is an Adjunct Clinical Professor of Dermatology at Lake Erie College of Osteopathic Medicine (LECOM). He has published numerous articles in peer-reviewed journals as well as served as an editor for the Journal of American Osteopathic College of Dermatology. Dr. Lim also invests in the future of dermatology by participating as a member in the Leadership Society for the Dermatology Foundation. Dr. Lim has served on the Board of the Pennsylvania Academy of Dermatology and Dermatologic Surgery (PAD) and was proud to have been elected as the 2019 President of PAD. Dr. Lim was also presented the 2020 "Dermatologist of the Year" Award by the PAD at its Annual Meeting in November 2020. The PAD’s mission is to promote the highest standards of dermatologic care and service in the Commonwealth of Pennsylvania. Together with the PAD, Dr. Lim advocates to preserve the patient-physician relationship, protect patient safety, promote education and research, improve health care delivery, and foster cooperation among dermatologic organizations and its members. In his free time, Dr. Lim enjoys quiet time with family, fly fishing, golf, and gardening.
