Meet The Team


Hi my name is Tanya and I've been an Expanded Functions Dental Assistant for 18 years. My goal is to make my patients feel comfortable and appreciated. I especially enjoy working with cosmetic dentistry cases. It's so rewarding seeing a patients eyes light up the first time when they see their new smile.

Working with Dr. Sinha and my co-workers is such a blessing! I can honestly say I love coming to work everyday!


Hello! My name is Jen Eckenfels. I have known since high school that I wanted to go into Dentistry. When I attended Oakville High School, I worked at a Pediatric Dental practice. I have been a Dental Assistant for fifteen years. I became a Certified Dental Assistant in 1999 and an Expanded Functions Dental Assistant in 2001. This is the highest level of formal education that a Dental Assistant can have and allows me to be able to take a larger part in creating our patients beautiful smiles!

I can honestly say that I LOVE MY JOB!!

I enjoy all the smiles I meet everyday and the variety of tasks I get to perform at my job now that I am able to do expanded functions. My favorite moments are when we encounter a patient who is very fearful of seeing a dentist and by the time they leave our office their fear has subsided and they have a great big smile on their face.

I also enjoy going to “Give Kids A Smile” twice a year. I love being able to help the children who would otherwise not have been able to see a dentist. I have been to Honduras three times to help more children and adults get the dental care that they so desperately need.

If you're looking for a new dentist, give us a call. You'll be so glad that you did. I look forward to helping you have or maintain your healthy beautiful smile!


Welcome to our exceptional team environment!

My name is Lilly, and I have been a registered dental hygienist since 1988. Prior to that I "grew up" in dentistry as a certified dental assistant from 1975-1986. I saw then, that dentistry would become my second family.

Having been in this profession for quite some time, I knew when I joined this dental practice in 2007, that this would be a caring and high-tech office , to extend a great experience to my patients. That is because we can all work together to make great things happen.

I would love to give you the personalized and professional care you truly deserve at every dental appointment, "knowing we can make the world a better place one smile at a time!"


Hello, I am Rita, Dr. Sinha’s Office Administrator. I have worked in the dental field since 1989 and can’t imagine working in any other field!

I love a lot of things about my job including helping you schedule convenient appointments, maximizing your dental benefits, helping with financial arrangements if needed, or just to help you feel as comfortable as possible while visiting our office. However, what I enjoy the most is meeting and really getting to know our patients. I have been fortunate enough to meet a lot of interesting people in the office since 1989, and look forward to having the opportunity to meet many more.

I am proud that we have a modern, high-tech office that offers state of the art dentistry and that keeping your appointments comfortable is important to us all.

If you happen to be looking for a great dental home, please call us, I will make sure you are taken care of in a fun, professional manner. Remember:



Hello, my name is Kasey Murphy and I am happy to be a part of Dr. Sinha’s dedicated dental team. I am a Registered Dental Hygienist with a Bachelors of Science Degree that I received from Southern Illinois University Carbondale in 2005. In my final year of hygiene school I had the life changing opportunity to go on a dental mission trip to Mexico where I was able to provide free dental care to a population that had never received dental treatment. I was married in 2008 to a wonderful man, Keith and have two beautiful children.

Patients are like family to the entire staff. During your dental appointment the focus on relaxation and a gentle technique gives you a positive dental experience. I look forward to meeting with you for your personalized hygiene therapy appointment, based on your individual needs. Using the latest dental knowledge, skills, and technology I am committed to helping you achieve a smile you will be proud of in a relaxing atmosphere.

Just remember, improving the health and appearance of your smile will not only make you feel better but improve your overall health and quality of life. I invite you to be a part of our dental family and achieve your goals.
