Meet the Doctors

Dr. Hector Bush | Dr. Zach Ehrmantrout

Hector Bush, DMD

Due to the recent changes associated with providing orthodontic care in Washington State, in combination with the necessity of social distancing, we are happy to announce we are going to be doubling the amount of available patient days and simultaneously reducing the number of patients that we see per day by greater than 50%. Hopefully, this will improve your patient care experience and ensure a healthier environment for us all. In order to make this possible, Dr. Ehrmantrout has partnered with Dr. Hector Bush, who has over 20 years of experience, and he will be exclusively dedicated to your services and needs.

We would like to assure you that both doctors will be reviewing all of your cases to assure a smooth transition and continuity of care. Dr. Bush is excited to be here and is looking forward to meeting you all and providing friendly, knowledgeable orthodontic care for you and your loved ones.

Dr. Hector Bush received a Bachelor of Science in microbiology from Howard University in 1987. In 1991, Dr. Bush graduated from the University of Pittsburgh School of Dental Medicine. In 1994, Dr. Bush earned his 2-year Certificate in Orthodontics from the Howard University School of Dental Medicine where he also completed his Graduate Orthodontic Residency.

Dr. Bush has recently moved to the area. For more than 20 years, Dr. Bush has been committed to providing quality orthodontic treatment to children and their families throughout the state of Georgia. Illustrating this commitment, he established the Share a Smile Program in 1994. Since launching the program, he has partnered with various organizations and has donated orthodontic care to children throughout the state of Georgia. He has partnered with the Methodist Home, the Beatrice Carey Steel Pitts Orphanage, Congressman Jim Maddox, and Dr. E.T. Walton.

In 2010, Dr. Bush had the honor of re-naming The Share a Smile Program, to The Dr. Andrew Young Sr. Share a Smile Program, in acknowledgement of the legacy of Dr. Andrew Young Sr., who practiced dentistry in New Orleans for almost 60 years, and is the father of civil-rights icon Ambassador Andrew Young Jr. Dr. Bush received the 2019 Howard University Distinguished Alumni award from the school of Dental Medicine. Currently, Dr. Bush is a member of the American Dental Association, American Association of Orthodontists, Washington State Dental Association, as well as the North Georgia Dental Society.

Please join us in welcoming Dr. Hector Bush as Dr. Ehrmantrout’s partner and the sole treating doctor at Cascade Orthodontics.
