Patient Testimonials

Spectrum Dermatology is top notch, I have seen at least half a dozen dermatologists over the years and am so happy to have found Dr. Zook. She is compassionate, intelligent, thorough, and so enjoyable to work with. I am definitely sticking with her.

~ Greg J.

Dr. Zook centers her practice on the concerns and needs of her patients. She determines the best course of treatment only after she has completed a thorough consultation and examination. After seeing her, I referred my mother to Dr. Zook so we are now a two-generation patient family!

~ Jill N.

Dr Paula Zook is a MAGICIAN. I had been to 5 other doctors and nobody could diagnose the problem as well as her, and she absolutely saved my life. She is very smart and astute with her diagnosis, and I am completely cured thanks to her. She literally saved my life and I couldn’t be more thankful. I highly recommend her!!

~ Ben P.

“Consistently great experience”
Appreciate the time and care that Dr. Zook gives to me as a long-time patient. She’s always thinking of new ways to support my care.
