Dr. Brandon Johnson

I was born and raised in Northern Virginia. My high school lacrosse and football coach, who was a dentist, impacted my life by his generosity and willingness to give his time to others. He encouraged me to excel academically as well as athletically and pursue a career in dentistry.

I attended James Madison University where I played college football and graduated Cum Laude with a degree in Biology. I then received my Doctor of Dental Medicine degree from the University of Pennsylvania, graduating Magna Cum Laude.

After graduation, I practiced dentistry in Columbia, South Carolina. I married the love of my life, Dr. Cornelia Duffin, before relocating to Central Texas.

With the profession becoming ever more technologically driven, training and experience with the latest and greatest in the digital world is a wonderful asset to any practice and we implement that here. Nonetheless, my driving force is to earn and keep the trust of every patient by carefully assessing what needs you have and
meeting them, skillfully exceeding your expectations.

Outside of the office, I’m a devoted father to my two kids. I’m a somewhat workout devotee, a football fan, and an intermediate golfer. You might find my wife challenging me to some one-on-one basketball or a round at the links.

Dr. Cornelia Duffin

I was born and raised in NJ as the middle child of 11 children.

Giving my all in sports and academics is something that’s always interested me. Even as a child I played multiple sports every season and was very excited by academics.

I received my Bachelor of Science in Exercise Science from Rutgers University, where I Varsity Lettered for their Division I field hockey program. During this time I was also an undergraduate T.A. in Physics. At Rutgers, my college advisor suggested dentistry. I was immediately hooked and was so excited to pursue dentistry.

I graduated Cum Laude from the University of Pennsylvania School of Dental Medicine where I also met my now husband, Dr. Brandon Johnson. Wanting to expand my scope of practice, I completed a one-year Advanced Education in General Dentistry residency program at Fort Jackson, S.C.

As a Captain in the United States Army, I practiced dentistry as a brigade dentist out of Ft Hood, TX. My responsibility as the sole dentist for approximately 2500 fellow soldiers included a 6-month rotation in Korea. I was humbled to receive numerous awards and coins while in the service for my attention to detail and care on the spot.

I’m a mother to my two beautiful children and enjoy family time. I love watching my kids grow and hope that people bring their whole families to our office. I want to break down barriers to people getting care – for people to feel comfortable expressing their concerns. I desire to make going to the dentist something you feel more comfortable with, give you a smile you feel more confident about, and maybe even make going to see us something you look forward to!
