Dr. Mariya M. Costa

Sixty years ago, I was a young Modoc boy growing up on the former Klamath Reservation in Southern Oregon. For no known reason, I wanted to be a dentist. I fulfilled that dream, and the experience has been rewarding beyond all belief and expectations. My appreciation of being a dentist has never diminished, but now I must pursue new challenges for personal and professional growth.

Join me in welcoming Dr. Mariya M. Costa to Eugene and our dental practice! As I fully transition from general dentistry into dental sleep medicine and open Eugene Dental Sleep Center, I am confident our patients will have continued excellent care in the hands of a talented and compassionate dentist.

Dr. Costa completed her undergraduate studies at UW-Seattle and received her Doctor of Dental Medicine degree from Roseman University College of Dental Medicine in South Jordan, Utah. You will find that Dr. Costa is committed to providing a high level of dentistry, especially with her broad clinical skill set. She has advanced training in dental implants, endodontics (root canals), wisdom teeth removal, and conscious oral sedation. You can count on her to continue the same comfortable and personalized care that you’ve come to expect from our practice.

Dr. Costa is a native of the Pacific Northwest with a deep appreciation for the area. When not in the dental office, she and her husband, Edward, explore nature by hiking and enjoy discovering new local restaurants. Dr. Costa and her husband are proud parents of two beautiful and rambunctious Labradors and a cat who takes herself much too seriously.

Dr. Costa will assume the dental practice in mid-December, and I will fully transition to my new dental sleep practice, Eugene Dental Sleep Center.

My time at this practice has been incredible, and I would like to thank my patients for your trust and friendship. As everyone in my practice will attest, it has been a pleasure and privilege to serve you. Thank you for your loyalty, and join me in welcoming Dr. Mariya M. Costa.
