APRIL HECKENDORF

Office Manager

April graduated from Lake Washington Technical College as a registered dental assistant in 1998. She assisted for three years before finding her love of the front desk. The part of her job she enjoys the most is getting to know you and helping you get the smile that makes you smile. With her knowledge of front and back office she is able to expertly explain to you your dental needs as well as help you understand your insurance and financing.

April started with us in 2011 managing our Mount Vernon location; in 2020 she also became manager of our Bellingham location. She has spent many years growing relationships with our patients in Mount Vernon and looks forward to doing the same in Bellingham.

When April is not working, she enjoys time with her husband, two boys and her dog Molly. Traveling is by far her favorite thing to do whether it be or somewhere entirely new, a crazy RV road trip or an impromptu trip to her favorite place to relax, Chelan, she loves the adventure that comes with traveling. She also loves camping, sunshine filled days on the lake, music, walks with her dog Molly and time with her friends around the bonfire.

Haley Koenig

Dental Hygienist

Haley works part-time as a registered dental hygienist here at the office. She started at Diamond Dental in 2020 as a temporary hygienist planning to help for a couple of days but stayed permanently because she “couldn’t get enough of the amazing team” (her words exactly)!

When she’s not studying for school, she enjoys hanging out with friends and family, getting out on a kayak or paddle board, playing pickleball, and traveling all around the world! She’s always excited to hear about others’ travel plans and welcomes fun travel recommendations! Next on her bucket list is Costa Rica and Switzerland!
