Dan Siapco joined Cascadia Eye in 2003, and rapidly gained a reputation in Skagit Valley as the doctor to choose for cataract surgery, winning the award from Northwest Business Monthly for “Best Northwest Doctors in Skagit Valley” after only a few short years here. Dr. Siapco is a board-certified ophthalmologist. He graduated from Loma Linda University School of Medicine, interned at Sacred Heart Medical Center in Spokane, and did his ophthalmology residency at the University of Pittsburgh.

Over this time, he has witnessed many improvements in this exciting technology. Dr. Siapco is available for exams and consultations in our Mount Vernon and Whidbey Island locations and provides surgical and laser procedures in our surgery center in Mount Vernon.
