Dr. Van Dusen’s Biography
It was a friend in middle school who started Dr. Van Dusen along his path toward dentistry. “What if we don’t make it to the NFL,” his friend asked. “What else would you like to do?” While attending dental school at OHSU, he fell in love with the state’s incredible scenery and decided to make Oregon his home. He brings the Aloha spirit to Willamette Dental, particularly excited when a patient chooses to go into the dental field after an affirming experience in the chair.
Though he didn’t make it to the NFL, Dr. Van Dusen is still athletic and spends many weekends watching a game with friends and family.

I came in earlier just to avoid traffic but they took me in earlier due to an opening. Always having pleasant interactions with the staff. My appointment was quick and even got done before my scheduled time. Thank you!

My child's first appointment was scheduled for a day that the facility lost power. While this is understandable, the only notice I was provided was an email which was sent in spanish only. I arrived at the appointment to find the facility closed. When I called to reschedule the appointment, the customer service person was less than empathetic and unapologetic. To make matters worse, when we rescheduled and went to the appointment, we checked in 10 minutes in advance of our appointment time. After waiting in the lobby for 20 minutes (10 minutes past our scheduled appointment), I asked for an update and the person at the front desk indicated that they messed up and the system never alerted the staff that we had checked in. I realize these were one-off occurrences, and typically I have no issues with the service provided by the Beaverton office, but it was frustrating.

Best ortho team ever!
Mar 31, 2025
Appointments are very hard to get and in a timely fashion. I am concerned that my appointments have been moved all over the place and could be extended out if certain things don't happen in a timely fashion, which I have no control over, and neither does the orthodontist, but the system is sort of not aligning with timing for our goals. Thanks.

This is the 2nd time my son has gone in for the box bracket and 2 times in a row the bracket comes off, customer service doesn't help and no one gets back to me.
