Dermatologist Amanda Friedrichs, MD

Sycamore’s Premier Choice for Dermatology

Dr. Friedrichs graduated magna cum laude from the University of Illinois in Urbana-Champaign with her undergraduate degree in biology. She earned her medical degree, also with honors, at the University of Illinois College of Medicine in Rockford and finished her medical internship at West Suburban Hospital in Oak Park, Illinois.

Dr. Friedrichs completed her dermatology residency at the University of Iowa Hospitals and Clinics. She began her career at the former Dekalb Clinic where she worked for nearly 7 years. In March 2015, her dream of owning her own practice in her hometown community became a reality and she opened the doors of Radiant Dermatology.

She specializes in the diagnosis and treatment of the many forms of skin cancer, acne, eczema, and psoriasis. Dr. Friedrichs also offers Mohs surgery, giving patients a local option to have facial and more aggressive skin cancers treated. Along with treating medical conditions, she also performs an extensive array of cosmetic procedures to provide patients with a refreshed appearance and radiant glow.

One of the most important parts of Dr. Friedrichs’ job is educating her patients about skin cancer and sun exposure. She is committed to continuing education so she may offer only the best skin care options to her patients. She regularly travels to professional meetings to learn about the latest trends in dermatology. She is also an active member and committee participant in the American Academy of Dermatology. Dr. Friedrichs was instrumental in bringing the AAD’s “Indoor Tanning is Out” campaign to sororities and fraternities across the US and to the DeKalb/Sycamore and NIU communities.

In her free time, Dr. Friedrichs enjoys running and leading an active lifestyle with her two sons and their family dog.

Learn More

Ashli Schoenholz is a nurse practitioner at Radiant Dermatology in Sycamore. With six years of previous nursing experience, along with a master’s and bachelor’s degree in nursing from Northern Illinois University, Ashli is a vital part of the Radiant Dermatology team where she loves working with patients on an individual basis and educating them about preventative measures that can promote an optimal, healthy life.

Since she was a child, growing up in Rochelle, IL, Ashli knew she would one day pursue a career in the medical field. After graduating from NIU with her B.S. in Nursing, she began working with Dr. Amanda Friedrichs in 2008 and immediately fell in love with dermatology.

In order to have a more central role in helping patients, Ashli decided to continue her education and earned her M.S. in Nursing, with a Family Nurse Practitioner specialization. When Dr. Friedrichs returned to the area to open Radiant Dermatology, the two reunited at the new practice.

When she’s not working with patients, Ashli enjoys the small town feel of the DeKalb/Sycamore area, and also leads an active lifestyle outdoors with her husband, two daughters, and son.
