A West Texas native, Dr. Marcus Whitmore graduated from the Baylor College of Dentistry in 1983. He opened his general dental practice in Plano in that same year. Since then, he has taken the forefront in evaluating new dental technologies and techniques, adopting those that will most benefit his patients.
To continually enhance his skills and knowledge, Dr. Whitmore invests countless hours in continuing education. He attended the first postgraduate Continuum of Aesthetic Dentistry held at Baylor College of Dentistry in 1994. Other courses he has taken include adhesive dentistry, implant surgery, aesthetic dentistry, periodontics, and endodontics.
Dr. Whitmore is a member of the American Academy of Cosmetic Dentistry, American Dental Association, Texas Dental Association, and the Dallas County Dental Society.
After hours, Dr. Whitmore enjoys making music as an accomplished saxophonist. He plays with a rowdy group called The Gener8ters, a band of dentists from around the country. Dr. Whitmore plays the only woodwind in the band and has even been known to grind out the vocals on a rock classic here and there. The band entertains at various dental seminars and conventions around the country and is always on the lookout for a new gig.
Dr Whitmore donates over 80 hours of services to North Dallas Ministries every year providing general dental services to underprivileged adults.
