Meet Our Team



Registered Dental Hygienist

Dr. Gardner is passionate about continuing education and training for our team in order to provide the absolute best experiences, care, and dentistry for our patients. Our team is one of a kind and we aim to exceed our patients’ expectations. It is a blessing to work for someone who cares about giving back to the community. Dr. Gardner has two annual volunteer events; one to serve our veterans (Dentistry for the Vets), and the other to serve the less fortunate of Montgomery Country (Dentistry from the Heart).

My husband and I have two beautiful daughters, Adalynn and Ariyah, and my son, Ayden. Aside from the busy life of work and home, I enjoy Bible study, spending time with my family and friends, camping, hiking, nature and traveling when I have the opportunity.

I am from Conroe, Texas, and graduated from Conroe High School in 2000. I took three semesters of basic courses at Lonestar College and decided to move to Colorado Springs with a few friends. While living there, I went to school for dental assisting at Intellect Medical Institute. Although I loved living near the mountains and enjoyed time outdoors, it just wasn’t home.

After completing the dental assisting program, I moved back home and worked as a dental assistant for six years. During that time, I continued my education at Lonestar College to become a dental hygienist while raising my first child, Ayden. I received my associate degree in dental hygiene in 2013 and have been working for Dr. Gardner ever since. Becoming a dental hygienist was my goal for several years, and I now strive to perfect my skills, continue to grow in my profession and provide excellent care to our patients.



Registered Dental Hygienist

Trisha joined our team in May 2022 after graduating from Fresno City College in 2009. She loves our team feeling and adherence to the golden rule, and she looks forward to growing and building strong patient relationships.

In her free time, Trisha enjoys camping, hiking, fishing and being outdoors.



Registered Dental Assistant

I have been in the dental field for 10 years and began working for Dr. Gardner’s office in 2012. The dental assistant position allows me to communicate and interact with patients. I enjoy helping patients overcome any concerns about their treatment and explaining the technologies and materials we use. I am also very happy to help patients who speak Spanish

I love the way all of our patients become part of our dental family. Our practice is dedicated to providing the best dental care to all patients. We do our best to make all patients’ visits as pleasant and comfortable as possible. I’m really honored to be part of this team. I am committed to making your dental visit very enjoyable.

During my free time I enjoy spending time with my husband and two kids, playing any outdoor sport or just relaxing at home watching movies.



Hygiene Coordinator

Brooke is one of the smiling faces at our front desk, and she joined our team in May 2022. She loves the kind team members she works with, and she brings her own determined work ethic to the mix.

Sabina completed her training at our very own dental assisting school and joined our team in September 2021. She is a reliable member of our team and is always willing to help others, she enjoys working with a team that shares the same values, and she always looks forward to the opportunities we have to give back to the community through our dentistry days and volunteer work.

Sabina is the second youngest of 12 kids, but she considers mostly everyone who lives in the valley family. When she is not at the office, she enjoys traveling, visiting family and friends, spending time with her dog, watching movies and true crime shows, and putting together 1000+ piece puzzles.



Treatment Coordinator & Team Leader

I enjoy working with Dr. Gardner and seeing him live out his God-given talent. His compassion and drive to care for his patients are outstanding qualities to witness. Working for him has given me the opportunity to not only help broaden my knowledge of the dental field, but to really expand my character traits in such a positive manner, as we give back to the community with our charity events.

I was born and raised in Mississippi and moved to Texas in 2016. I am happily married to my husband, Luke, and we have two beautiful daughters, Avery and Abigail. During my free time, I enjoy reading books, being outdoors, and spending time with my family. I also enjoy checking out all the local festivals.

In 2012, I earned my associate degree in applied science. I became a registered dental assistant in 2018 by attending the Montgomery County Dental Assisting School. I am also certified in CPR and have experience in medical coding. I have been in the healthcare industry for almost eight years, and I began working with Dr. Gardner in 2017.

Rebecca obtained her registered dental assistant training after moving back to Texas from Casper, Wyoming. She has been in the dental field since 2009 as a dental assistant, insurance coordinator and treatment coordinator. She enjoys everything involved in dental and has been continuing her education at Lonestar College in hopes of obtaining her degree in dental hygiene. Rebecca loves that we start each day with a morning prayer. Everyone is very kind and willing to teach her how to better herself in the dental field.

Rebecca has two beautiful daughters and is married to a Navy veteran. They love animals and currently have four dogs and a tortoise. They never know what they will end up with next! In her own time, Rebecca loves to travel, ride motorcycles and do anything outdoors, especially fishing. Any time she spends with her family is special to her.


Tracey Tsitso

Marketing Director & Team Leader

I joined Dr. Gardner and his team in March 2020. I am really enjoying being part of this team and truly enjoy my work. We begin each day with a team prayer, and it is honestly the best way to start our day.

I am married and have three sons. I enjoy spending time at the beach under an umbrella in a comfortable chair with my husband and try to go as often as possible. I enjoy traveling and have been blessed to visit many places in the United States and many other countries. My absolute favorite travel was a trip we took to Italy, where I was fortunate enough to attend a Catholic high mass by a cardinal in a 3,000-year-old cathedral in Genoa. It was an incredibly amazing spiritual experience! I really love volunteering in the community. I’ve volunteered as a Catholic faith formation teacher, breast cancer charity fundraiser, American Cancer Society committee member, and American Heart Association fundraiser. I have also volunteered on several American Diabetes Association campaigns, as my oldest son has Type 1 Diabetes.

I live in Spring, Texas and moved to Texas in 1995 from Chicago. I literally started college the actual day I took my youngest son to kindergarten. I studied communications, marketing, journalism and have a passion for overall wellness. I was previously a Corporate Wellness Coordinator for a global company and have always worked in health care.
