    Dr. Straffon and his team are the absolute best in the business! They have helped both of my children with braces/Invisalign as well as my wife and I with our Invisalign. My dentist told me that I would need to wear a bite guard as the misalignment of my teeth was leading to gum decay, which would ultimately lead to major long-term problems. My middle-school aged daughter had such a great experience with 303 smiles that she actually booked my first appointment for me to get me going on my Invisalign journey! Dr. Straffon and his team made every step of the process comfortable, clearly understood, and personal. The entire team at 303 Smiles is friendly, patient, and very thorough and professional. The relief of having my bite fixed, and knowing that I have long-term dental health, is very comforting. Plus, I now smile every chance I get to show off my perfect teeth! Thank you to Dr. Straffon and his wonderful team!

    I’ve been a patient at 303 Smiles for about a decade. During these years, Dr. Straffon and the team have spent significant time and consideration towards custom building the perfect smile for me. They consistently make sure I understand each procedure, how it will help my smile, and then execute. Lastly, the entire staff has shown me nothing but genuine kindness and always ask about my life. I couldn’t be happier with how far my teeth and smile have come.

    From the second we walked in Dr. Straffon and the whole team treated us like family. We just moved from IL and my husband just died of brain cancer. We were starting over and they all made the process easy and had endless empathy for us from payment plans to flexibility on scheduling. Dr. Straffon is incredibly meticulous and managed to make my daughters dreams come true by wrapping up right before her birthday and prom this year. Her smile is gorgeous and her confidence has improved too. As a parent, it’s great because he makes the kids part of the process and be accountable. He is honest about timing and expectations. Dad jokes are abundant and his memory for each patient and their needs is impressively detailed. 303 Smiles also has the latest technology which really provides an amazing tool to perfect the outcome.

    I’m so impressed with how my daughter’s teeth turned out, I’m now a patient too. This place is like finding a lottery ticket. We walked in and didn’t have a lot to smile about yet left with a beautiful new smile as we start over. I can’t recommend them enough.

    I can't give enough praise to Dr. Straffon and the 303 smiles team.
    The office is inviting and warm and everyone there is happy and supportive to their patients.
    From my consultation to getting braces, I was blown away at the level of customer service, thoughtful education and explanation of services and options, and exceptional communication when I call the office. Dr Straffon is thoughtful, honest and kind.

    Anyone needing orthodontics should consult 303 Smiles.

    I am proof that what Dr. Straffon and his capable crew can do for youngsters also works beautifully on folks in their later 70's. I highly recommend 303 Smiles. Jerrie Eckelberger

    Dr. Straffon and his team took excellent care of me. I came in for Invisalign to correct some misaligned teeth and the results are incredible. Even after years and years of braces and retainers as a kid, my teeth have never looked or felt this good as they have since seeing Dr. Straffon. He worked with me to be able to dial in not only my alignment, but also my bite. I never knew what a proper bite felt like until after getting Invisalign. Dr. Straffon really took the time to get to know me and my teeth and you can tell he pours his heart into all of his patients. 10/10 would recommend his services to anyone looking for a better smile.
