Dr. Clark Steffens DDS

Dr. Clark Steffens is a graduate of Baylor University in Waco, Texas, where he earned his Bachelor of Science in Biology. He then went on to receive his Doctor of Dental Surgery degree from Baylor College of Dentistry in Dallas, Texas. After spending his first seven years practicing in Uptown Dallas, Dr. Clark (as he is known to his patients) moved to the Frisco area to start LIV General and Cosmetic Dentistry and start a family with his wife.

Dr. Clark is a constant student of dentistry and enjoys learning about the newest techniques and technology in the field. He is Invisalign certified and enjoys all areas of cosmetic dentistry including crown and bridge restorations, implant dentistry, and porcelain veneers. He loves the way his patients glow after they see the beautiful results of a smile makeover. “A beautiful smile can change a person’s whole outlook,” says Dr. Clark, “and everyone deserves to smile with confidence.”

Being a member of the American Dental Association and the Dallas County Dental Society allows Dr. Clark to stay active in the dental community. Through this network of colleagues, he is able to stay abreast of the latest methods being used in dentistry as well as participate in continuing education programs, volunteer opportunities, and mission trips to other countries.

When he’s not thinking about teeth, Dr. Clark loves to play with his dog, spend time with his wife, catch a ballgame on television, and practice his favorite hobby, cooking. When his time as a dentist is over, he hopes to open a small, hole-in-the-wall restaurant where he can continue serving people in a new way.

Stephanie Steffens

Stephanie grew up in Binghamton, New York, and moved to Texas back in 2010 to pursue a new career in dental office management.  It was during this time that she and Dr. Clark met at a dental conference and both immediately knew that they were a match made in heaven.  They were married about three years later and have continued their shared passion for the dental field by creating LIV Dentistry in 2014.  Dr. Clark often refers to Stephanie as “the boss” as she makes our office GO.  From managing the financials to presenting treatment plans to planning our marketing, Stephanie has her hand on everything at LIV.  When not busy with work, Stephanie enjoys hitting the pool, personal fitness, and playing with her lovable dog, Reagan!

Nicole Suitt

Nicole grew up in Aledo, Texas, which she still calls home.  She got her dental assisting license at the National School of Dental Assisting in Frisco, Texas, and has been in love with dentistry ever since.  Dr. Clark met Nicole when she was an intern just “getting her hours”, but once those were completed, he just couldn’t let her go.  While proficient as a dental assistant, Nicole handles our front desk and insurance issues, but is always at the ready to step in to help with our patients when needed.  When she is not working, Nicole or “Nic” as she is often called, enjoys the outdoors, water sports, and grilling on the patio!

Mary Nguyen

Mary is our wonderful hygienist that came on with LIV back in 2015.  She is a local product from right here in Lewisville, Texas.  She received her dental hygiene license from Sanford Brown in Dallas and has been cleaning teeth ever since!  Mary loves her job and says that she gets the most satisfaction from educating patients on their dental health.  Like all of our staff, Mary enjoys seeing the transformation of frightened patients into folks that genuinely enjoy coming in for their cleanings and maintenance.  When she’s not cleaning teeth, you can find Mary either shopping or hanging out with friends.
