The College of Optometry at Western University of Health Sciences has produced some very good doctors in their short time. Dr. Bladh's office has been privileged enough to be trusted as an externship site for the college where we are given a handful of students for each rotation. During this time with the students, we get to teach them about the profession of Optometry at the same time giving them hands-on experiences with our patients.

One such student that came through our office was Dr. Jeffrey Chen. He is a local product of Diamond Bar and an avid golfer, so much so that he earned a scholarship to the University of Notre Dame! Yes that Notre Dame. We were so impressed with Dr. Chen's experience and work ethic that when he graduated we offered him a job right away. He's been a wonderful addition to our staff and actually took his final year of Optometry school traveling across the country to different rotations so he could get extensive experience in comprehensive eye exams, diagnosing, treating and management of eye health conditions and diseases as well as co-managing LASIK procedures. Dr. Chen is also one of the few Optometrists in California licensed to treat glaucoma.

He has participated in local community vision screenings, with one of his favorites being helping with the Special Olympics. He has traveled to Vietnam and Honduras to provide vision care. Some of his interests include hiking, college football (Go Irish!), international travel, food and of course golfing. Come in and meet with our new doctor 909.861.3737.
