Dr. Maria Rosa de Jaureguizar Tesas joins the Oregon State University Gary R. Carlson, MD, College of Veterinary Medicine as an assistant professor of small animal emergency and critical care. She will perform clinical duties in the Lois Bates Acheson Veterinary Teaching Hospital. Dr. Tesas earned her veterinary degree from Universitat Autonoma de Barcelona in Catalonia, Spain. She practiced in private hospitals in Spain and United Kingdom, then pursued further specialization through internships across United Kingdom and United States. She then completed her small animal emergency and critical care residency at the University of Georgia.
What attracted you to Oregon State and to academia?
My transition into academia is driven by a desire to combine high-level clinical practice with direct clinical teaching. Oregon State University stood out immediately for its collaborative hospital culture, strong commitment to education and providing the ability for tailored education matching each student's needs. Having recently completed my residency in emergency and critical care, I wanted an environment where I could contribute to grow an established ECC service while continuing to grow professionally alongside dedicated specialists and house officers.
What most excites you about being part of the ECC team here at OSU?
What excites me most is becoming part of the dynamic ECC service at OSU. Emergency and critical care relies heavily on seamless communication between faculty, residents, interns, veterinary technicians and staff. I am eager to join a young growing service, helping define and shape it. Being able to collaborate with other specialty services allows us to provide the highest standard of care for complex cases, and I look forward to contributing to that high level of medical excellence.
What's your philosophy of patient treatment and care?
My clinical philosophy centers on evidence-based, compassionate and patient-tailored critical care. In emergency medicine, it is vital to balance rapid, life-saving interventions with thoughtful, individualized care plans that account for the patient's overall quality of life. Equal importance lies in client communication: emergency visits are often distressing for pet owners, so clear, empathetic and transparent communication is essential. I aim to ensure that families feel informed and supported during difficult decision-making processes, treating every patient with the same diligence and care I would want for my own companion.
As a faculty member in a teaching hospital, what do you hope to bring to the students/residents/interns you'll be working with?
I hope to foster an approachable safe learning environment where clinical curiosity and critical thinking are actively encouraged. Emergency medicine can feel overwhelming to learners, so my goal is to break down complex pathophysiologic concepts into practical, structured approaches for triage and stabilization. For residents and interns, I aim to be a dedicated mentor who supports their preparation for board certification, clinical autonomy and professional well-being, helping them build confidence under pressure while mastering advanced critical care techniques.
What do you enjoy most about your work?
What I love most about ECC is the immediacy of our impact and the continuous problem-solving required in critical care medicine. Guiding a critically ill patient through a life-threatening crisis and seeing them recover to go home with their family is incredibly rewarding. Equally fulfilling is witnessing the "lightbulb moments" with students and house officers when a complex critical care concept clicks on the clinic floor, or when they successfully execute a critical procedure for the first time.
