We are one of the few specialty clinics in the United States treating pilonidal disease

Evergreen Surgical Pilonidal Clinic

We are one of the few clinics in the country with a special interest in treating difficult pilonidal disease. We routinely take care of patients with pilonidal cysts, non-healing pilonidal wounds, and pilonidal abscesses with great success. In contrast to most surgical practices, we encourage patients with the most extensive recurrent disease to come see us!

Dr. Steven C. Immerman has been treating pilonidal disease using the Cleft-Lift procedure for approximately twenty-five years. He recently spoke about his success at the International Pilonidal Sinus Conference in Berlin, Germany to a group of pilonidal surgeons from around the globe.

Patient Testimonials

Read our patient’s comments on this website, and on our Facebook  reviews.

“I can’t tell you in words the difference that Dr Immerman has made in my son’s life. He is able to go back in 6 weeks to playing college football after being sidelined from other sports after a failed prior surgery for 6 months. My son was able to sit the next day after surgery, after not being able sit for 6 months. Took 1 dose of Ibuprofen and no narcotics at all. He was back to doing all normal activities after drain was removed 1 week after surgery. He was released to play college football after 6 weeks and hasn’t had any issues at all with the surgical scar at all.”
16+ years with my pilonidal cyst, 3 surgeons, and close to 2 dozen surgeries done on the area. I was skeptical at first thinking there was no way it would ever get fixed. To my surprise Dr. Immerman fixed it. I never thought I would ever be able to say I’m free of this issue. And now I can!”
