Dr. Stacey and his brother Dr. Steve attended dental school together. After graduating they decided to return to the Sacramento area — where they lived as young children — to take advantage of the proximity to the mountains, lakes, and rivers.

Dr. Stacey believes that successful dental care happens when you educate the patient and involve them in decisions. By using the latest technology, such as digital x-rays and intra-oral photos, he can help the patient to visualize their treatment options. He strongly believes in staying current with dental advancements. To do this, he attends many dental education seminars each year. Dr. Stacey has trained with some top dental educators, such as Spear Education at the Scottsdale Dental Center.

He and his brother Dr. Steve were among the first dentists in the area to become CEREC® certified and offer porcelain crowns and onlays, made at their office, in just one visit.

Dr. Stacey lives with his wife Sheila in Lincoln, CA along with their 5 children (4 girls and 1 boy). He loves being a dad and stays involved in all his kids’ sports and activities. He is also an avid water skier, both with and without skis, and enjoys spending time with his extended family at the lake.
