Premier Allergist – Bethlehem Welcomes New Provider!

Premier Allergist is excited to announce that Yi Feng Dennis Chen, MD, is joining our team! Dr. Chen is a dual board-certified allergist who brings exemplary allergy and immunology skills, qualifications, and experience to the care team.

Dr. Chen is available to see patients starting March 18th and will provide additional coverage for Dr. Schenkel as he begins to transition away from practicing medicine full-time. This opportunity to transition to part-time care will allow Dr. Schenkel to spend more quality time with his family while still doing what he loves – taking care of patients! We are thankful for the Premier Allergist network of providers, who are always more than willing to serve patients wherever needed.
