Arnell Prato, DDS
Dentistry is my passion. My number one goal as a Dentist is to help my patients maintain and improve their dental health. Each person is unique and has individual needs. That's why I take time to carefully listen to each of my patients and understand their immediate concerns. I always give my patients treatment options that take into account their dental health, overall health and financial constraints. I take patient well-being very seriously.
I attended The Ohio State University for both my undergraduate education and dental school. I love learning about dentistry and will never stop finding new ways to provide my patients with the best care possible. As part of my continuing education, I have taken extensive coursework in implant dentistry, cosmetic dentistry, dental occlusion and bite analysis, oral surgery and pharmacology.
Earlier in my career, I practiced dentistry in Ohio, Louisiana and Canada. Before moving to Washington state, I served the dental needs of the aboriginal people of northern Canada, working in remote, under-served areas of the Arctic. My work there helped develop my "Down to Earth" philosophy, where reliable and long-lasting dental work is the primary goal.
I'm a native of the Philippines, and moved to the U.S. in 1984. I love living in Washington and enjoy all the outdoor activities our great state has to offer. When I'm not in the office, you can often find me kayaking, visiting farmers markets and exploring the beauty of Washington State. I also enjoy international travel and have visited more than 70 countries.

When DJ isn’t assisting doctors with dental procedures, you can usually find him playing Fortnite or some other video game or listening to music. You can sometimes find him dancing to music. If you pay close attention, you might even catch DJ dancing in the office!
