Meet Dr. Catherine Smith

I come from a long line of dentists and was the seventh-generation in my family to graduate from Washington University. I started in the dental field when I was 12, helping my father in his practice. Then I became a dental assistant and finally a dentist. One could say it’s genetics that brought me into dentistry. I was a Marine Biologist before dental school, but when finding work became difficult, I went with what I knew and loved…teeth.

I enjoy working with patients of all ages, but especially with the children in our practice. I love children and love to see them develop great smiles and healthy jaw joints. It thrills me to watch their faces light up when they can close their mouths properly, breathe better, and fully enjoy their lives. Seeing a child smile and laugh, comfortably and with confidence, and knowing I made that happen, is fulfilling.

I love working with my husband, Dr. Michael Papademetriou. Ours is a true family practice. We discuss each patient’s treatment together and enjoy creating smiles that truly change lives.


Dr. Mike and I are both staunch advocates of continuing education. We enjoy learning about the latest research and treatment techniques. Knowing new theories and treatments helps us offer the best care and options to our patients, ensuring a functional and beautiful smile.

We have studied in many countries, throughout the world, and work with many different dental and orthodontic issues. I’ve spent a lot of time studying about caring for special needs patients, including people on the Autism spectrum, and those with Down’s Syndrome, ADHD, anxiety, and panic disorder. I’ve also studied airway and myofunctional treatments and CBCT (Cone Beam Computer Tomography), or 3-D radiographic imaging.

Personal Life

I grew up in Phoenix, AZ and graduated from Central High School. I’m proud to be a fourth-generation Phoenician. My family came here in the mid-1800s; Charlebois Springs in the Superstition Mountains is named for my great-great grandfather.

Dr. Mike and I have been married for 28 years. We spent the first 21 years of our lives together living in Cyprus. We have three children. Michelle has come to Phoenix, and is our office manager, Stephany is attending Northern Arizona University and is following in the family footsteps to become a dentist, and Christopher is also at NAU, but isn't sure what he wants to do yet. We share our lives with our Bolognese dogs, Chippy and Bella.

When I’m not working, I enjoy traveling around Arizona, especially visiting Flagstaff. Dr. Mike and I frequently travel to orthodontic meetings, too. I also enjoy time at my sewing machine, working on various quilting projects. One of my favorite pastimes is Temari, a form of Japanese embroidery that helps me focus and calm my very active brain.

Integrity.  Commitment.  Excellence.
