Membership: Dr. Lori Gibson

I have had the great fortune to serve on the PVMA Executive Board since 2010. During this (me, I have seen first-hand how involved our veterinary community is. I also have had the unique perspective to watch the PVMA grow over the past 4 years, and to see and be involved in the incredible vision the board has that will propel the organization forward. I am very much looking forward to continuing to do what I can to assist with this vision. I grew up in Portland, and graduated from the University of Portland, and am a 1999 grad of Oregon State University and Washington State University Colleges of Veterinary Medicine.  I founded Compassionate Care Home Pet Euthanasia Service, P.C. in 2009 – we are devoted to helping pets and their people stay at home during end of life.

Community Animal Welfare: Dr. Sonja Lapinski

As a relatively recent grad and native Portlander, I am looking forward to the opportunity to run for the PVMA board this spring. I attended the Catlin Gable School here in Portland for the first 13 years of my education, then went East to Walla Walla for my undergraduate studies at Whitman College. I wound up back in the Willamette Valley at Oregon State University for veterinary school several years later. Between my bachelors and DVM degrees, I got hooked spending my summers as a deckhand on a commercial sockeye gillnetter in Bristol Bay Alaska - a nasty habit that I kept up for almost 10 years. AGer a rota(ng small animal internship in Tucson, I returned to the Portland metro area, where I have been doing relief work ever since. My first exposure to organized veterinary medicine was in veterinary school where I was very active in student organizations, particularly our amazing student-run and funded international program. I co-presided over this club for several years, and served on our annual trip to Nicaragua 4 times. These experiences as veterinary student, combined with what I have observed during my internship and "new grad" phases, have kindled a passion for organized veterinary medicine as a vehicle for change and communication within the profession. I am particularly interested in working with the PVMA to foster support and mentorship for new grads, and in bringing discussions about our rapidly changing profession to the local level. Working as a relief doctor in many different hospitals with many different teams has also been a wonderful and fascinating experience, informing my desire to be part of this larger organization. I have been a PVMA member since 2012, and have been very impressed with the vitality and activity of this group.

Publications, Marketing, and Governance: Dr. Alon Kramer


After receiving my DVM degree from UC Davis, I completed a year-long internship, after which I returned to UC Davis for a 3-year small animal surgery residency. Upon attaining ACVS board certification, I worked one year as staff surgeon at a Santa Cruz, California referral practice. I then joined a multi-specialty practice in Portland, where I was an associate surgeon for more than three years. I Then joined Cornell University Veterinary Specialists, a multi-specialty private/academic hybrid advanced care facility in their New England location, where I had a central role in creating, establishing and operating the hospital’s surgery department.  My family and I underestimated our deep ties to, and affection for the Pacific Northwest area, and we returned to the Portland area in 2012, when we established OREV, a locally and independently operated specialty clinic.

My surgical interests and experience include all aspects of orthopedic and soft-tissue surgery, as well as neurosurgery. I get immense satisfaction from my profession, but Veterinary medicine is not all that I am about...
