Dr. Regina Tobin attended veterinary school at Cornell University. Following her graduation in 1994, she completed a one year internship in small animal medicine and surgery at Angell Memorial Animal Hospital in Boston. Dr. Tobin then spent a year in general practice in the Boston area before starting her small animal internal medicine residency at UC Davis. She became board certified in small animal internal medicine in 1999. Dr. Tobin has worked in clinical practice in Oregon since 1998, with the exception of a two year period when she worked as a consultant for a major diagnostic lab.

Although she manages dogs and cats with all types of complex medical problems, Dr. Tobin is well known for her expertise in liver disease, kidney disease, gastrointestinal disease, immune mediated disorders, and hormonal diseases.

Dr. Tobin feels strongly that her role as a small animal internist is to offer clients all diagnostic options that are available for their pets, provide compassionate high quality care to her patients and support her clients through difficult decisions.

When she is not working, Dr. Tobin enjoys camping, reading and traveling. She has started horseback riding, an activity she enjoys with her daughter.

Dr. Klaser grew up on the west coast and earned her undergraduate degree at UC San Diego.  She then headed to the University of Georgia (go Dawgs!) where she worked as a research assistant and then graduated from veterinary school with the class of 2000.  Her next move took her to New York City, where she completed her internship and residency at the Animal Medical Center, becoming certified in small animal internal medicine in 2004.  She worked in a large referral hospital in Annapolis, MD in the years since, enjoying many of the east coast amenities.  

2019 brings her west again, and joining Sunstone feels like she is coming almost full circle.  She is looking forward to 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. 

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 her 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). 

Dr. Jani Remsburg graduated from Oregon State University's College of Veterinary Medicine in May of 2000. Dr. Remsburg joins the team at Sunstone after working as a small animal general practitioner in Battle Ground and Longview, Washington for the past 14 years. Prior to this, she was a mixed animal veterinarian in Burns, Oregon, and a small animal veterinarian in Idaho Falls, Idaho.

During her years in practice, Dr. Remsburg has always enjoyed challenging internal medicine cases. She is excited to join the team at Sunstone as an internal medicine fellow to support the specialists with their cases and provide families with help for their pets.

Dr. Remsburg was raised in Deer Island, Oregon, and is blessed to be back living on what was her grandparents' 45-acre farm. She lives there with her husband, Mat, dogs Bliss and Roo, and cat Minnie along with many farm animals. When she is not working, she enjoys hiking, backpacking, cooking, sewing, and traveling.

Dr. Lily Su is a Board Certified Veterinary Surgeon and she is thrilled to be serving the Portland pet community at Sunstone Veterinary Specialists! She has focused her veterinary career specifically on the practice of small animal surgery since 2005.

Her training and education have taken this native Californian all over North America.

Dr. Su’s journey to become a Board Certified Small Animal Veterinary Surgeon began at UC Davis School of Veterinary Medicine. After vet school, she completed internships at Angell Animal Medical Center in Boston, and Wheat Ridge Veterinary Specialists in Colorado, followed by a fellowship at the University of Wisconsin. 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.

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.
