Jennifer Thornton-Office Manager

I became a dental assistant at the young age of 19 and now have about 15 years experience under my belt. I began my career in San Antonio, where I was born and raised. I moved to Portland about nine years ago and started working with the Allen Dental Family. One of my favorite sayings is “Do what you love, and you’ll never work a day in your life.” I feel blessed to be able to say that I love what I do! Outside of work, I enjoy attending my son and daughter’s sporting events and reading long books.


 Robin Terry – Patient Coordinator

Originally I am from Maryland but have lived in Virginia, where I began my dental career as a dental assistant in 1994. I have extensive experience in all areas of the dental office and enjoy working with people. In 2004, I moved to Aransas Pass with my husband and two sons. I started working with Dr. Cuellar in 2009 and have found a new home working with this team. In our spare time our family enjoys spending time at the beach and having fun in the South Texas sun.



Corrin Ebby-Registered Dental Hygienist

I am a Dental Hygienist originally from Dripping Springs, Texas.  I joined the dental field at a young age, but have been practicing dental hygiene for five years now.  I graduated from Coastal Bend College in Beeville, Texas in 2010 and I love my job.  Our practice at Allen Portland Dental is the best place to work!  When I’m at home I enjoy hanging out by the pool with my husband and our five sons.  I also enjoy yard work, exercise and going to the beach.

 Hollie Swierc-Registered Dental Hygienist

I am a 1999 Gregory Portland HS graduate. I graduated from Del Mar College in 2001 with an associate’s degree and a certificate as a certified dental assistant. As I was working as a dental assistant, I was actively pursuing becoming a registered dental hygienist. In 2005 I graduated from Del Mar College as a registered dental hygienist.

I’m married to my hero, a Portland fire fighter! We have two awesome children together. In my free time I enjoy spending time with my husband and kids. 



Danielle Gutierrez-Registered Dental Assistant

I have lived here in South Texas my whole life. I graduated from the Dental Assisting program at Del Mar College in 2011. I was very fortunate to find my job with Dr. Cuellar during my externship and began my dental career in the summer of 2011. I really enjoy coming to work everyday with Dr. Cuellar and our wonderful team. I look forward to a long and exciting career in dentistry! Outside of the office, I enjoy shopping, music, traveling, and spending time with family and friends.
