Mark Hochman, D.D.S.
Family Dentist in La Plata, MD
La Plata Dental

I was born and raised in Brooklyn, NY.  After graduating from Long Island University with a business degree, I immediately went to work for Union Carbide Corporation, handling government contracts. I quickly became restless and needed a greater challenge, so I left the company in 1970, after almost 2 years.  I returned to school part-time so I could accumulate the necessary requirements for dental school.  In 1972, I began my journey on this new road...and never looked back.

I started practicing dentistry in Washington, D.C. in 1977, first downtown on 19th Street, N.W., and then on M Street, N.W., until 1990.  One weekend, I went to a small community in Southern Maryland called Solomon's Island to buy a boat.  I bought the boat, fell in love with this quaint waterfront town, sold my practice in D.C., moved to Solomon's and, again... never looked back.  I now live with my wife and our dog in a lovely home on a peaceful knoll overlooking a beautiful creek in Mechanicsville, Md.  I love my home, practicing dentistry, and living life.  I believe in living this life to the fullest and have seen how beautiful, healthy smiles can positively affect people's lives.  I enjoyed practicing in Leonardtown, in St. Mary's County, from 1990 to 2010, and continue to practice in our La Plata, MD office.

Andrew Betaharon, D.D.S.
Family Dentist in La Plata, MD
La Plata Dental

I am a Maryland native who graduated from the University of Maryland, College Park in 1999.  After graduating with degrees in management information systems and finance, I went to work as a technology consultant.  Realizing that my career was not fulfilling for me, I decided to pursue something that would allow me to work more directly with people and have a direct impact on people’s lives.  I resigned from my job and began to pursue a career in dentistry.  I spent a year at Georgetown University, gaining the prerequisites for dental school, and continued on to the University of Maryland, School of Dentistry, where I received my Doctor of Dental Surgery degree.  Following graduation, I continued my training with a general practice residency at the Veterans Affairs Hospital in Long Beach, CA, where I provided comprehensive dental care to our nation’s veterans.   After my residency, my wife and I returned to Maryland to be closer to our families and to raise our own families.  We now have four children with whom we spend most of our time…either playing, helping with homework, or enjoying the outdoors.  I have been working with patients in Southern Maryland to provide healthy, happy smiles since 2011, and look forward to doing the same for you!

Terra Colliflower - Dental Assistant

I was born and raised in St. Mary's County, MD and presently live in Bushwood with my husband, Josh of 13 years.  We have two children, a son and a daughter.  I have always loved spending time with my family and friends. During high school I studied child care because I enjoyed working with children.  After babysitting for family and working for the New Generation Day Care Center, I knew I wanted a career serving people.

Dr. Hochman was my family dentist and during an appointment my mom asked him to give me a job. Lucky for me, she talked him into it.  As a senior in high school, I had taken morning classes at Chopticon High School and then trained to be a dental assistant with Dr. Hochman in the afternoon.  Dental care was quite different from child care, but I soon developed a passion for it and have been loving it since the day my dental career started, nearly 20 years ago.  I love interacting with my patients and making them smile.

Healthy, pretty teeth make a great smile and build confidence in each individual's life.  I work hard to help each of our patients achieve this.  We look forward to greeting you with a smile and hope when you visit our office, we give you something to SMILE about!
