Board-Certified Internal Medicine Specialist
Medical Director, Co-Founder

Raised in Hawaii and California, Dr. Elliott is a native of the Pacific Basin and loves the Pacific Northwest for its cooler climate, warm and friendly people, and dedicated pet parents.

Dr. Elliott’s training and expertise as a veterinary internist allows him to focus on his patient’s especially complicated medical problems. While he enjoys all aspects of internal medicine, he is particularly skilled in ultrasound and endoscopy and has trained many veterinarians in these modalities. His goal is to help his patients live higher quality lives through thoughtful diagnostics and careful treatment.

The Pacific Northwest is the place Dr. Elliott chose to plant roots and ultimately launch his own private practice, where he could deliver the highest standards of care without corporate constraints, as well as be able to make a good life and future for his family. They love all that the Pacific Northwest has to offer. Dr. Elliott especially loves snowboarding and training in Aikido, where he holds a black belt.

Debra Klaser, DVM, DACVIM (SAIM)

Board-Certified Internal Medicine Specialist

Dr. Klaser grew up on the west coast and earned her undergraduate degree at UC San Diego.

2019 brought her west again, and joining Sunstone felt almost full circle. Dr. Klaser loves being back on the coast “where sunsets belong over the ocean”, where she is close to family and some favorite friends, and where she can be surrounded by the beautiful northwest and its people. 

Accordion Content

She is one of the lucky few who have truly always known what she was meant to do, and is grateful to her mentors along the way, from those who gave her that pivotal first job in a veterinary clinic in 10th grade, to those who trained and helped her become the clinician she is today. Dr. Klaser enjoys many aspects of internal medicine, particularly endocrinology and ultrasound. She finds that the most rewarding part of her job is getting to know her patients and their families as she helps manage some complicated and multifaceted medical scenarios.

Dr. Klaser and her husband have 2 children, Sabrina and Finn, so they keep quite busy. They typically have at least one geriatric cat and a yellow Labrador living in their home. Dr. Klaser considers the journey of parenthood to be her greatest life accomplishment, and in her spare time enjoys reading, spending time outdoors, and cooking (especially over a campfire).

She completed her residency in small animal surgery at the University of Saskatchewan in 2011. Following her residency she taught small animal surgery at The Ohio State University.

Accordion Content

Her desire to bring high quality, comprehensive, and personalized surgical care to each patient made Dr. Su a perfect fit for Sunstone. While she enjoys using the skills her years of training and education have given her, she feels her greatest success is in seeing her patients return to a normal life. To that end, she is also a Certified Canine Rehabilitation Practitioner. Dr. Su works with her clients, their primary care veterinarians, and local rehabilitation facilities to provide the very best outcomes for her patients through their post-operative recovery.

When not working, Dr. Su enjoys spending time with her perfect (but slightly naughty) herd of animals, trying out interesting places for food/drink, and exploring the mountains and rivers of the Pacific Northwest.
