Meet The Doctors


Greetings to all my valued patients,

I have found an excellent dentist to help me  here at the office  and to take care of everyone for me on the days I am off.  Her name is Dr. Nadia Sulieman.  Please read her introductory  greeting to you.

For now and the foreseeable future, my plan is to continue  working at least two or three days a week.  This will enable me to spend more time with my grandchildren and maybe take a vacation or two!  I put my complete faith in her ability to provide each and every one of you with exceptional care.  I know you all will do your best to make her feel welcome.

Thank you,

Dr. Mahan

Nadia Sulieman, DMD

My name is Nadia Sulieman and it is my honor to meet many new faces and get to know all of your smiles and stories.

I attended University of South Florida and majored in Biomedical Sciences. I have been practicing since 2015 after graduating from Nova Southeastern University and I am currently working on my fellowship with the Academy of General Dentistry. The learning never stops in this field and this is one of the reasons I love it!

When I am able to I provide mentorship and support to other doctors in the field of dentistry as it is a great passion of mine. I believe that continuing education courses to further advance skill sets is of the utmost importance, and a responsibility all healthcare practitioners should share. It is our responsibility to provide our patients with the optimal treatment to ensure long lasting oral health and smiles.

Early on in my career I spent many hours volunteering for the Florida National Guard, as well as many free dental days in which we provided free dentistry for those that were unable to afford care on their own.

At home I enjoy my time discussing dentistry and navigating parenthood with my husband who also practices dentistry. We have two beautiful daughters and a poodle. We are currently raising our girls to appreciate Pink Floyd, good southern BBQ, F1 racing and you guessed it, teeth!

I look forward to meeting and taking care of Dr. Mahan’s patients who are essentially, like family. I take this trust placed in me seriously and I look forward to having the chance to get to know each face.
