Meet Dr. Grisius

Dr. Grisius is board-certified by the American Board of Orthodontics.

My love for my chosen profession is deeply embedded in my childhood as the son of a Georgetown University Dental School professor who grew up watching my Dad rehearse lectures on the dining room wall with his old Kodachrome slide projectors. My fascination for the specialty of orthodontics, however, did not surface until I was in my second year of dental school when introduced to the amazing bio-mechanical concepts of tooth movement. The fact that applying forces to a tooth elicits a cascade of cellular actions at the root- to- bone interface causing the tooth to move was fascinating to me – I was hooked!

Working with my hands, combining medicine and art, and helping create a great looking and functional smile is rewarding to me. I have the opportunity to be part of my patients lives for several years, seeing them every month or so and getting to know them on a personal level. The treatment process is a time of growth as the patient becomes more confident and his or her self-esteem develops. I am part of this process and get to watch the transformation; I can’t imagine a more fulfilling profession!

I am also passionate about providing a caring, comfortable and open environment in our office. Patients receive the highest level of clinical and personalized care and we do not take our patients for granted.

Ortho doctor


  • Bachelors of Science – Virginia Tech
  • Doctorate of Dental Surgery – Medical College of Virginia (VCU)
  • Masters of Science, Orthodontics – University of Detroit Mercy

I am an ardent believer in the fundamental concepts in dentistry and adhere to a conservative, evidence based philosophy of orthodontics.  I do not employ the latest “fad” treatment concept touted on the lecture circuit until its outcomes are published in reputable peer reviewed journals.  I am a firm believer in lifelong learning and am a 20 year member of the Greater Loudoun Study Club.  I have published several journal articles, co-authored a text book chapter and serve as Assistant Professor of Orthodontics in the graduate orthodontic clinic at the Virginia Commonwealth University School of Dentistry.

Board Certified

I recently completed the American Board of Orthodontists re-certification exam. The ABO Board Certification is a voluntary credential that represents an orthodontist’s personal and public commitment to the standards of specialty practice and lifelong learning. The ABO Certification process requires the completion of peer-developed, externally validated written and clinical examinations. A Board Certified Orthodontist has reached this level of achievement by pursuing additional voluntary education and ongoing self- assessment. Board Certification is considered a confirmation of an orthodontist’s personal commitment to providing lifelong quality patient care.

Beyond the Practice

My wife, Heidi, and I have called Purcellville our home for more than 20 years. Our two boys, Clay and Henry, are involved in a variety of activities including: hockey, golf, 4-H, theater, piano and jazz. Supporting their activities occupies a good portion of our free time. Otherwise, you will find us taking care of our chickens, goats, pigs and all of the yeoman’s duties required to maintain our property.
