Dr. Wayne Dudley

Dr. Wayne Dudley joined Dixie Oral Maxillofacial & Implant Surgery in 2007 after serving 22 years in the
U.S. Air Force. Retiring at the rank of Colonel, his last assignment was as Chairman of the Department of
Oral and Maxillofacial Surgery at Mike O'Callaghan Federal Hospital located at Nellis AFB in Nevada. Dr.
Dudley’s 34 years of experience is unmatched in Southern Utah.

Dr. Dudley has performed Oral and Maxillofacial Surgery in hospitals across the United States and
around the world, and is qualified to provide a full scope of care in oral and maxillofacial surgery with an
emphasis in dental implant placement, wisdom teeth and other surgical tooth removal, bone grafting,
corrective jaw surgery, and oral pathology. He earned his B.S. degree (Biology major) from Utah State
University and his doctorate of Dental Surgery from University of Washington School of Dentistry.
Following graduation, he entered the U.S. Air Force and completed his General Practice Residency at
Offutt AFB in Nebraska. His oral and maxillofacial surgery residency was at the Air Force’s premier
medical center in San Antonio, Texas.

Currently on staff at Dixie Regional Medical Center, Dr. Dudley is Board Certified by the American Board of Oral and Maxillofacial Surgeons and is a member of the American Association of the Oral and Maxillofacial Surgeons, the American College of Oral and Maxillofacial Surgery, the American Dental Association, Utah Dental Association, the Southern Utah Dental Association. He has been actively involved as an educator throughout his career, teaching in General Practice Residency and Advanced Education in Dentistry programs as well as doing extensive lecturing on oral and maxillofacial surgery topics. He regularly attends surgical conferences to stay educated on current technologies, techniques and standards of care.

To give back to the local dental community, Dr. Dudley, along with Dr. Matthew Mizukawa, created the Southern Utah Study Club in 2015. Its membership of approximately 35 locally-based dentists meet monthly for educational topics, practice updates as well as to confer with other professionals in the community. Dr. Dudley continues to maintain a role as a moderator, a regular lecturer and a facilitator to bring in guest lecturers from universities or specialty practices around the country. A Utah native (Heber City), Dr. Dudley and his wife Rebecca (Becki) love to spend time, especially outdoors in Utah, with their three children and their spouses as well as their rapidly growing number of grandchildren. They remain active in the community and church.

Dr. Matthew Mizukawa

Dr. Matthew K. Mizukawa became a partner at Dixie Oral Maxillofacial & Implant Surgery in January 2014 after serving as an Assistant Professor in the Department of Oral and Maxillofacial Surgery at Vanderbilt University Medical Center in Nashville, Tennessee from 2012 to 2014. He continues to serve as an Adjunct Clinical Professor at Vanderbilt as well. He is Board Certified by the American Board of Oral and Maxillofacial Surgeons and is also on staff at Dixie Regional Medical Center(DRMC).

A highly-qualified and experienced oral and maxillofacial surgeon, Dr. Mizukawa obtained a B.S. in Neuroscience from Brigham Young University and a Doctorate in Dental Medicine from the University of Nevada at Las Vegas School of Dental Medicine. Dr. Mizukawa completed his oral and maxillofacial surgery residency at Vanderbilt University Medical Center in Nashville, Tennessee, where he was chosen amongst hundreds of medical and surgical residents as the Best Consultant to the Department of Emergency Medicine for his work in emergency medicine and trauma surgery in 2009. He served in private practice following graduation but soon after took the offered opportunity to return to Vanderbilt to teach in the residency program.

While the majority of his practice is centered around management of wisdom teeth and dental implants, Dr. Mizukawa continues to enjoy and excel at the full scope of oral and maxillofacial surgery. He provides emergency services at Dixie Regional Medical Center in managing trauma involving the entire facial region. He has been integral in treating some of the most complex facial trauma cases seen at DRMC, including gun shot wounds to the face and severe automobile accidents. Facial reconstruction is another area that Dr. Mizukawa enjoys, including the reconstruction of facial defects from trauma or tumors using bone from the hip and free vascular flaps from the leg. He and Dr. Dudley continue to provide corrective jaw surgery services to those patients in need.

Dr. Mizukawa is a frequent lecturer at professional organizations and schools, and will be presenting at the Anesthesia Update of the annual meeting of the American Association of Oral and Maxillofacial Surgeons(AAOMS) in September 2019. He is the lead editor and co-author of “Anesthesia Considerations for the Oral and Maxillofacial Surgeon,” a comprehensive reference book designed to help practitioners navigate the complexities of office-based anesthesia, including patient evaluation and selection, pharmacology, monitoring, and management of the myriad comorbid diseases in the perioperative period.

In 2017, Dr. Mizukawa was appointed by the AAOMS to be on their Committee on Anesthesia, a committee of about 10 oral surgeons specifically designated to ensuring the safe and efficient administration of office-based anesthesia. This committee is constantly reviewing current guidelines and policies that govern anesthesia and providing updated recommendations to governing boards on the state and federal levels. Continuing education and training specific to anesthesia are other key roles that this committee plays in promoting safe anesthesia in the oral and maxillofacial surgery setting.
Dr. Mizukawa is a member of the American Association of the Oral and Maxillofacial Surgeons, the American Dental Society of Anesthesia, the American Dental Association, the Utah Dental Association and its local chapter, the Dixie Dental Association, where he has served on the board of directors for several years.

To give back to the local dental community, Dr. Mizukawa, along with Dr. Wayne Dudley, created the Southern Utah Dental Study Club in 2015. Its membership of approximately 35 locally-based dentists meet quarterly for continuing educational topics, practice management updates, and mutual enlightenment through group discussion of difficult cases from the community. Dr. Mizukawa continues to maintain a role as a moderator, a regular lecturer and a facilitator to bring in guest lecturers from universities or specialty practices around the country.

Dr. Mizukawa has long enjoyed rock climbing, mountain biking, hiking, wakeboarding, snowboarding, camping and loves to be outdoors in general. As a father of 6, he has been alarmed at the continual reports of declines in the physical and mental health of adolescents and teens, supported by staggering statistics from the Centers for Disease Control and Prevention. Most concerning are the skyrocketing rates of depression, anxiety, suicide, suicide attempts, and suicidal thoughts, as well as self-harm. This is largely associated with the also alarming rate of screen time (television, tablet, computer) in children. In 2018, Dr. Mizukawa founded Get Outside, a non-profit organization in Southern Utah to provide opportunities, education, fellowship, and financial support to kids to get outside and engage in outdoor recreation. Get Outside has established a Club in each high school in Washington and Iron Counties to help kids overcome 3 main barriers to getting outside: lack of opportunity, lack of education, and lack of finances. His program frequently organizes outside community activities and can be found online at: www.getoutsideutah.org, on Facebook at: getoutsideGO and on Instagram: @get_outside_go

Dr. Mizukawa was raised in Ft. Washington, Maryland, but graduated from Pine View High School in 1996 in St. George, UT. He served as a missionary for the Church of Jesus Christ of Latter-day Saints in the Japan Fukuoka Mission from 1997-1999. Upon returning from Japan, he attended BYU, where he met his wife, Julie. They now have six children and love living in southern Utah, close to family and the outdoors.
