Proudest career moment

My proudest career moment was leaving my job in the post anesthesia surgical unit (PACU), to pursue my career in Aesthetics and Cosmetic Dermatology. I knew that I was stepping out in faith to follow my dreams.

When I’m not at Pūr

I’m boating with family and friends, enjoying being an auntie to a bunch of littles, and trying to become as good as my husband at golf.

On my nightstand

A photo of the sweet Boy named Constance, who I sponsor in South Sudan. He’s such an amazing boy who has big dreams to be a Doctor someday. I love our letters back and forth!

Favorite skin challenge

Treating acne is near and dear to my heart, since it’s been a challenge of mine for 8 years! Specifically hormonal acne because I am passionate about helping patients find root causes as well as being part of the incredible change we see with treatment modalities and medical grade skincare.

Guilty pleasure

Chocolate of course! Who doesn’t love some dark chocolate with some local Woodinville wine???

The tool I’m always reaching for

My dermaplaning tool. Dermaplaning is a great treatment for almost everyone that instantly brightens a dull, tired looking complexion and removes unwanted hair and dead skin cells.

I’ll cry if I’m out of

Retinol. Nothing has changed my skin quite like it! It does take some time for the skin to adjust, but I’m addicted to the brightening, smoothing and acne fighting properties it has.

The product I always reach for

Neuromodulators like Botox and Dysport! It’s hands down the best treatment for every patient.


Love this place! I have had the best Botox treatment ever administered by Denice and I’ve had microdermabrasion that was perfect for my sensitive skin. I’ve sent two of my friends there. I highly recommend PUR.

Denice has been wonderful! She is very knowledgeable and experienced in her field of work. She was able to provide me with answers to my concerns. Overall it has been a wonderful experience for me as I knew that I was in good hands. I’m looking forward to my next visit.


Denice was highly recommended by a friend 10 years older than me. My friend looks beautiful while also natural and not like she’s “trying” to look younger. Denice listens to my priorities each time I see her and works very carefully to fulfill them. I consider Denice a tool in my beauty toolbox, like workouts and eating well. With her help, I feel more beautiful than ever!

Here’s what she had to say.
