About

Bio

After attending Medical School at Washington University in St. Louis and training in Pathology at University Hospitals of Cleveland at Case Western Reserve Medical Center, I find myself loving the West Coast life just north of Seattle, WA, practicing in a large multi-state Pathology group, CellNetix Pathology and Laboratories. I presently serve on its Board of Directors and am the Medical Director of Anatomic Pathology at Providence Regional Medical Center Everett. Although a general Pathologist, my specific interests include Breast Pathology and Cytopathology and help to run the Interdisciplinary Breast Cancer Conference at my Hospital. My spare time is spent traveling, reading, doing crossword puzzles and collecting vintage baseball cards. Please feel free to contact me with any questions.

Specialties
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.
