The first time I thought about being an orthodontist was at age 17. My sister needed braces and orthodontic treatment for her crooked teeth. This had a big impact on her life because she was extremely self-conscious about smiling and sometimes even talking. As my sister went through her treatment with braces, I witnessed her whole personality change and ultimately so did her life; this was amazing! It is truly a profound experience to witness someone you care about go through such an awesome transformation. I believe this is where my passion for braces and orthodontics stems from.

I have a friendly and fun loving team at Simply Orthodontics; they are like family to me. I also take pride and enjoy the relationships that I build with each of my patients and their families.

The ability to create beautiful, confident smiles and the  possibility of transforming someone’s life for the better is what put me here and keeps me going in the amazing world of orthodontics!

  • “I just wanted to take the time to give some praise to this office and all the staff. My daughter got braces today and everything went great. The staff and all the doctors are very friendly and helpful. My daughter was a little bit nervous about getting her braces and the staff made her feel so comfortable. A+'s in my book.”

  • I like the service we receive during my son's appointments. I love the fact that when we are early, 99% of the time we are taken early. Most appointments are very quick. This last appointment was bitter sweet. Usually his Dad brings him to his appointments but he had passed away three weeks previous. I was going to mention it while we were there but they had already known and everyone made a point to extent their condolences to my son. It was very thoughtful and I appreciated it very much. Thank you!
