The first thing people notice is our lovely turn of the century office. Built in 1908, it was remodeled by Dr. Trenkle in 1993 and built exactly to her specifications. Truly a one-of-a-kind building, it houses the Dermatology practice as well as Dr. Trenkle’s Pathology lab. We offer a wide variety of medical and cosmetic dermatology as well as dermatologic pathology. Please look at our assorted options on the menu above for descriptions of procedures and diseases we treat. We are proudly helping patients in Redlands, San Bernardino, Riverside, and Inland Empire, CA.
