Care worth flying for 🛫 While we always have patients traveling from all corners of the DMV to experience our level of patient care, we also welcome patients from out of state (and sometimes overseas!) who travel hundreds of miles because of trust. 🥹

Whether you walk over, battle the inner loop, or earn frequent flyer miles to see us — know that our team is here to always put your unique goals, needs and values first. Your health and comfort are our number one priority.

Over the years we have seen how shifts in health and dental care have become insurance-driven and overtaken by corporate-owned clinics — leading to practices shortening appointment times, double booking patients to meet quotas, and compromising patient care. We have seen how this decline in quality leads to greater patient suffering.

We refuse to fall in line. BECAUSE YOU DESERVE BETTER. 🫶🏽

When you walk through our doors, your care is never rushed. You can trust that we are putting your health first — taking time to understand your concerns, educating you on options, and utilizing the best materials and technology to best suit your needs. And to top it all off? Our team is super nice!

So, if you are looking for a new dental home, we would love to meet you. Give us a call at 703-406-8600 to experience the Team Claustro difference and smile easy knowing you are in great hands. 💕

As a faculty member with , my role is to help elevate and educate fellow clinicians… but I always find myself experiencing my own growth at each of these weekend courses. This community of docs — students and instructors alike — is comprised of the most supportive, genuine, and energetic group of humans. 🫶🏽

This weekend I am returning home being reminded why us dentists do what we do… to share our expertise and joy with the world. Inspiring and healing smiles. Changing lives with our artistry. ✨

Because of my investment in advanced dental education and team development, I have been able to bring my vision of a comprehensive, relationship-based dental practice to life. And my patients are healthier and more confident under my team’s care. As always, I look forward to returning back to my practice on Monday knowing that I am providing a higher level of dental care and human connection than other dental clinics.

These Olympic athletes have me leaning into being my most authentic self ( you are a queen!!), so here’s my unpolished announcement from my kitchen… Due to the snowy weather, we will be opening the practice to patient care on a 2-hour delay on Monday February 23rd to allow patients and team members ample time to get to their appointments safely. I will continue to monitor road conditions throughout the evening and into the morning. My fingers are crossed that roads will clear up — because small business owners and moms across the region can handle another snow storm! 😅🫠

My team and I will be monitoring phones/texts/emails starting at 7am and we hope to be in the office for our 10am appointments. If you are currently scheduled or need to schedule, please call or text at 703-406-8600. And circle back to this account for updates! 💗

Lunch with the gals! During the day we are always on the go — moving together in a coordinated effort to care for our patients and support each other. So it’s nice to slow down, share good food, and catch up on each other’s lives. I’m always thankful for my team and the work they put in. 🫶🏽 Work-life balance isn’t just for after-hours. 🍲

Shout out to for a terrific lunch!

Wishing everyone a happy Valentines Day! A special shout out to this guy, who has been by my side since we were 18. 💗 When we met I wanted to be a screenplay writer. I’m thankful for him standing with me through the many pivots since 1998.

Tonight we are spending time with our son at the in DC! How are you celebrating love and friendship this Valentine’s Day?

Another year around the sun and I’m feeling so lucky and blessed to be surrounded by amazing people day in and day out. 🩷 A huge “thank you” to my team for making me feel special today! And for this beautiful charcuterie board made by hand by one of our hygienists’ husbands. It’s stunning!

Thankful for a beautiful life filled with beautiful humans. 🫶🏽 Happy birthday to me!! 🙋🏻‍♀️

Whether you spent this weekend enjoying the great outdoors with your kiddos ☃️, cozying up by a fire with a cup of coffee ☕️, or rewatched your favorite hockey romance (if you know you know! 🔥) — we hope you embraced the chance to slow down and enjoy the moment.

Today (January 27), we will be back in the office to inspire smiles. Due to weather and school closures, we will be operating on a condensed schedule with limited team coverage from 10am-2pm.

It is our highest priority to make sure our patients and team members feel safe on the roads. If you have requested to be rescheduled a member of our team will be in touch in the upcoming days to make sure you don’t fall off track with your dental health.

As always, we will continue to monitor weather and road conditions as this winter unfolds. Stay warm. Stay safe. And don’t forget to floss! 🥰

How did you spend your snowy weekend? ❄️🏒🏂🛷

And that’s a wrap on patient care for 2025! 🫶🏽 We are always so thankful for the trust our patients have in us to care for their smiles. This team of amazing women are always inspiring and motivating patients to meet and exceed their healthy goals — and always having fun in the process!

As an educator and clinician, I am always learning and leaning into opportunities to grow. Dental technology is ever-changing and I love investing in the latest gadgets — but sometimes putting the technology into use can be daunting! And, honestly, some technology has been sitting on my desk starting at me with longing eyes waiting to be put to good use. 🫠

I am so thankful for the folks at for putting together courses that help me gain greater understanding and confidence in implementing an even greater digital workflow in my private practice. I’m excited to put my education to work on Monday and to see how my team and patients are positively impacted by my strengthened knowledge! 🙌🏽
