Practice Coordinator/Marketing Director

Greetings, and thank you for taking the time to read my professional bio. My name is Ann, and I have the pleasure of serving as Dr. John's Practice Coordinator at Advanced Dentistry. I joined the team in September 2022, bringing with me over two decades of experience in the dental industry.

My passion for dentistry began in 1992 when I received my associate in medical business degree from San Jacinto College. I went on to earn my associate in dental hygiene degree from Wharton County Junior College in 1999. These degrees provided me with a solid foundation in dental care and business operations, enabling me to pursue a range of roles, including dental assistant, front desk staff, insurance coordinator, manager, and dental hygienist.

In 2009, I realized my dream of becoming an entrepreneur by opening my own dental assisting school. Over the next decade, I owned and operated the school, training the next generation of dental assistants while simultaneously launching several dental offices from the ground up. These experiences gave me a unique perspective on the dental industry, and I take pride in sharing my knowledge with patients and colleagues alike.

At Advanced Dentistry, I work closely with Dr. Varghese P. John and our team to provide exceptional dental care to our patients. Whether you need routine cleanings or complex procedures, I am confident in our ability to help you achieve and maintain a healthy smile.

When I am not working, I enjoy exploring new places, capturing memories through photography, watching baseball games, and spending time outdoors with my family and two furry companions. I have been a Houstonian for over 46 years and currently reside in Sugar Land with my husband and stepson.

Thank you for considering Advanced Dentistry for your dental care needs. I look forward to meeting you and working together to keep your smile healthy and bright.

Front Desk and Patient Coordinator

Hello, I am Yvette, and I am thrilled to be a part of Advanced Dentistry since the beginning of 2022. Although new to the practice, I bring with me a wealth of experience in the field of dentistry. I began my career in April 1999 as an office manager for a well-established dentist. During my tenure there, I gained a deep understanding of front office operations, insurance regulations, and Medicaid protocols. My passion for ensuring that patients have a great experience from the beginning of their visit to the end motivated me to learn how to assist the dentist with patients.

In the fall of 2000, I moved on to another dental office, where I applied my front office knowledge and expanded my skills as a dental assistant. Over the years, I honed my dental assisting skills, from taking accurate and clear X-rays to anticipating the dentist's needs to make procedures more efficient. As a result, I was promoted to Lead Dental Assistant, where I worked closely with the dentist to plan and execute treatment strategies for patients. I assisted in a variety of surgeries, including simple tooth extractions and implant placement for the All-on-4 procedures.

One of the things I enjoy most about dentistry is educating patients on the importance of maintaining good oral health and helping them achieve the smile of their dreams. I believe that every patient deserves to have a personalized treatment plan that takes their unique needs and preferences into account.

In summary, I am a seasoned dental professional with over two decades of experience in the field. I am committed to providing the highest quality of care to our patients and look forward to serving the Advanced Dentistry community for many years to come.

Treatment Coordinator

Hello, I am thrilled to share my dental journey with you. My fascination with oral health and teeth has been lifelong, and it led me to become a Certified Dental Assistant in Florida in the late 90s. I spent several years working closely with my dentist and patients, learning the ins and outs of dental procedures and providing high-quality patient care.

Eventually, I transitioned to the front office, where I focused on billing and insurance. I quickly discovered that helping patients navigate the complex world of dental insurance and financing was incredibly rewarding. By educating patients about their coverage and exploring creative financing options, I found that I could help them get the dental treatment they needed and deserved.

Today, I am proud to be a part of a dedicated dental team in Texas. My passion for helping patients understand and access the care they need is stronger than ever. I work tirelessly to help our patients make the most of their insurance benefits and find affordable financing options when necessary.

There is nothing that brings me more joy than doing what I love with a team that I love. Together, we strive to provide exceptional dental care and make a positive impact on the lives of our patients.
