About Us

Dr. Jones obtained his medical degree from Penn State University College of Medicine, which is located in Hershey, PA, "Chocolatetown, USA". The Hershey Trust donated $60 million to Penn State University to build the medical school in Hershey. They did this in honor of the founder of the Hershey Company, Milton S. Hershey a world renowned humanitarian.

Dr. Jones founded Rocky Mountain Allergy, Asthma, and Immunology in July 2008, and he continues to honor Mr. Hershey by creating a "chocolate" office. When you come to the office, you will get a flavor of Dr. Jones' personality as the office is decorated in a Hershey's chocolate theme. This includes a "Cocoa Castle" play area for children and also rooms decorated in "Hershey's", "Reese's", "Kisses", and "Twizzlers" themes. Hopefully, our office is more welcoming to you and lets you get to know Dr. Jones better.
