Bio

Before joining The Portland Clinic in 2008, I practiced emergency medicine in Missouri for eight years. Now I practice urgent care exclusively. What I find most fulfilling about acute care is being able to recognize subtle but potentially serious medical conditions, and to help stabilize patients before they are sent for emergency care.

I grew up in Manila, Philippines, and completed my medical degree and internship there. In 1991, I moved to the United States, where I finished my medical training, completing an internal medicine residency at St. Joseph’s Hospital and Medical Center in New Jersey and a fellowship at Stony Brook University Hospital in New York.

I thrive by maintaining a healthy balance between my career and my family life, and by making time for my personal interests, which include international travel and music.

Please note: Dr. Vallejo practices in our urgent care department and can’t be chosen as a primary care provider.
