Our Services

Dr. Doug Crosby

Dr. Crosby, the CEO of MINT Orthodontics, is a highly-trained orthodontist from Richardson, Texas with years of experience in orthodontics, lecturing at local dental schools, and building patient relationships since opening his privately-owned dental office in 1983. He grew up in Richardson and received his Bachelor's Degree from the University of Texas with Magna Cum Laude honors. He went on to complete his degree in dentistry from Baylor College of Dentistry, his orthodontic degree from the University of North Carolina at Chapel Hill, and has been an Associate Clinical Professor at Texas A&M College of Dentistry for the last 29 years.

Dr. Crosby's honors and awards include the American Board of Orthodontics Board Certification, Odontological Honor Society, Omicron Kappa Upsilon, Leadership Award, City of Richardson (2008), the Tom Matthews Teaching Award, and he was the former President of the Richardson East Rotary Club. However vast his accomplishments, Dr. Crosby will tell you that his greatest achievements have come from his community involvement, volunteering countless hours through his local Rotary Club, and founding the Network Dental Clinic in 2009 to serve uninsured children in the Richardson Independent School District.

The facet of Dr. Crosby's practice that brings him the most joy is the life-long relationships he is able to establish with his patients. "It is the opportunity to know them, to watch their children grow up, to celebrate marriages and births, to share the excitement of a new home or a job promotion, to see photographs of new children and grandchildren, to praise good report cards and athletic accomplishments that make this job worthwhile and most meaningful to me, " said Dr. Crosby.

When he’s not working in the dental office, teaching, or volunteering, Dr. Crosby takes on the role of an avid sports photographer. He takes photos for many of the local high school sports teams, college soccer teams, NFL Green Bay Packers, and has won numerous photography awards for the work that has been published in several sports publications. He also enjoys golf, tennis, yoga, cycling, and skiing—not to mention time with his beautiful wife, 3 children, and 3 grandchildren.

The ManBehind It All

Dr. Field Harrison is passionate about taking people out of pain. It could be dental pain, it could be spiritual pain, or mental pain, or loss of dignity pain, or financial pain. Even before he graduated from dental school, he was traveling to Romania with other doctors and dentists to end a village's suffering with tooth and jaw pain.

He spent many dental school weekends assisting other dentists in a free south Dallas clinic. He founded MINT dentistry with the conviction that outstanding dental care should be affordable to everyone.

He's a devout Christian who welcomes doctors of all faiths to MINT. He provides free dental care to soldiers who've suffered grievous tooth and jaw injuries in combat. He and his wife Sabrina privately assist employees in dire financial need. He's an in-demand speaker on entrepreneurship, leadership and faith. Many organizations are the beneficiary of the Harrisons' generosity.
