Meet Dr. Qutub

A Portland, Oregon native, Board-certified dermatologist Omar N. Qutub, MD FAAD created Defining Dermatology in order to better serve his patients according to their individual needs.

Formally trained in medical, surgical, as well as cosmetic dermatology, he enjoys the variety and breadth of his specialty, and is often complimented for his thoroughness and approachable bedside manner.

Dr. Qutub strives to deliver quality care for all of his patients understanding that a nuanced approach may be necessary in order to achieve both beautiful, natural results and complete skin health based on the patients desires and goals.



"Beautiful clinic and amazing staff! Dr. Qutub is extremely knowledgeable, personable and so thorough. We talked at length about my goals for skin care - and I’m so happy with the results!"


"Amazing experience at DxD and Dr. Qutub is an expert in his field. I appreciated the time he took with me to go over what I was looking to accomplish and how we could get results. He is patient, professional and his office and team are top in the industry."


"I had a skin condition that had previously been misdiagnosed by another doctor. Dr. Qutub correctly diagnosed my condition and gave me a new medication that made my symptoms go away in 2-3 days. Amazing. So happy with the result!"


"I absolutely love the staff and the doctor. I felt heard, not rushed, able to ask as many questions and curiosities as possible. I would highly recommend coming here for your dermatological needs."
