Generations of experience.

Mitesh Jivan, DMD, MPH


Dr. Mitesh Jivan was born in Luanshya, Zambia and raised in Tallahassee. At a young age, he become very interested in both biochemistry and health. After graduating with high honors from University of Miami with a Bachelor of Science in Biochemistry, he entered into the Ph.D. program at Florida State University. Fortunately for us, he decided dentistry would be his career. While attending Nova Southeastern College of Dental Medicine for his Doctoral training, Dr. Jivan also obtained a Masters in Public Health.

Since graduating, Dr. Jivan began honing his skills in private dental practices around the Fort Lauderdale area, where he focused on surgical aspects of dentistry (implant surgery, bone grafting, etc).

Dr. Jivan is a proud Mt. Dora Dentist, and continues to provide cutting edge dental procedures utilizing the most recent technological advancements.

I’m a proud daddy and husband, and each day I am honored to serve such a beautiful community.

Jane Walsh, RDH

Dental Hygienist

Originally from NY. I graduated from University of Bridgeport (CT) with an A.S. in Dental Hygiene. In 1983, my husband and I moved our family to FLorida. We have lived in Sorrento since 2004. Bob and I have three children; Chris, Cami & Keith and 7 grandchildren – ages 3 to 19.

Marie Len, RDH


Hi, my name is Marie Len. I have worked as a dental hygienist for 30 years for the office of Dr. Joan Lenze. I was raised in Orlando and became a Certified Dental Assistant and then went onto received my AS degree in Dental Hygiene in Jacksonville. I moved back to Orlando and started with Dr. Joan as her one and only Dental Hygienist, I guess I could be called the senior hygienist on many different levels. You can find me working at the front desk with Janet as well as my dental hygiene duties. It has been my honor to work and raise my family in the Mt. Dora-Eustis area.

My husband of 26 years, Bruce Len, was a reluctant dental patient and after 2 years of cleaning his teeth he sent me roses after his dental appointment. We have 2 children, Kyle, graduated from University of Miami (go CANES) and Dana a licensed massage therapist and yoga instructor.

Our office is a tight knit group of women who have shared many joys and sorrows. Our dental friendships have spanned the years. You could not ask for a better place to work and it reflects in our attitude that we treat our patients like the family and friends they are.

My husband James is a farrier and we have four children – Tara, Chace, Brooke, and Dustin. We also have 10 beautiful grandchildren! In our spare time James and I are also cattle ranchers with the help of our son and daughter-in-law!

I have enjoyed dental assisting here and watched so many of our patients grow up, have kids and bring them into our office. We have a wonderful family practice and a great group of girls working here. I look forward to continuing the quality work and friendly atmosphere that we strive to provide our patients!
