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.

Dr. Zook is very thorough and knowledgeable. She explains things well and is prompt at returning results. On top of that she is kind and approachable. I couldn’t ask for a better dermatologist!

Geri Gottlieb

I fly in from Palm Springs , California to see Dr. Zook . I trust her completely with all aspects of my dermatological health and well being. Dr. Zook is clear, direct and factual when answering any and all questions I have. Beyond the skin care and screenings , Dr. Zook is the only person I trust with any cosmetic enhancements as well. As long as she practices and as long as I need dermatology care ,I will be flying to see her a couple times a year.

Nancy

Always an excellent experience. Dr. Zook is professional, courteous and very caring. I enjoy my interaction with her and always feel well taken care of.
