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.

Patient Reviews

Excellent, knowledgeable providers that can handle any minor or major issues. Dr Zook is my provider but Ive seen a few other Dr's and the PA and they are also great. The staff is very helpful. They always work to squeeze me in asap. I like that there are only about 4 providers so you always feel like youre getting personal service.

Always a pleasant experience with Dr. Zook. The office is efficient, courteous and I always feel well taken care of.

Experience and trust ,

Aimee Sarkee is amazing! She has treated me since I was 18. I'm inmy 60s now. Best asset!!!!

The physician was on time, courteous, interested in what I had to say, asked appropriate questions and dealt with the issue at hand. I was very pleased.

I have been going to Dr Zook for many years and referred my family members to her. She is efficient and thorough in her exams. She is board certified in internal medicine as well as dermatology which enhances her ability to consider the patient’s medical conditions in her plan of care decisions. She is also personable and engaging.
