Welcome to the dental office of Craig D. Cheng, DDS and Bethany M. Kum, DDS. We welcome open communication and transparency in what we do.

Our Mission is to provide the highest quality of care and education, personalized to each individual’s needs. We treat everyone (patients and team members) in our safe space with kindness, compassion, patience, humility, and respect. At our office, we take an educational approach to dental care because our goal is to empower patients of all ages to maintain optimal oral health. We offer more than just single-tooth dentistry, and if you have a dental issue we treat the underlying cause rather than just the symptoms.

✨ Farewell & Best Wishes ✨

Today we say goodbye (for now) to one of our beloved families 💕. Mom has been part of our dental family since childhood, cared for by Dr. Malouf at our Altadena location. Over the years, they remained with us as Dr. Cheng carried on Dr. Malouf’s legacy — and even journeyed with us through the challenges of the fires and our temporary space.

Now, this wonderful family is off to start a new chapter in North Carolina! We are so grateful for your trust, loyalty, and the joy you’ve brought to our office through the years. You’ll always have a dental home here with us, and we wish you nothing but the best in this exciting new season.

Love always, Your Dental Family 🦷✨

🌟Finally! Last week we had two days together for team learning and bonding! 🌟

Dr. Bethany usually spends just one day a week with a team member for procedures at another office, while the rest of the crew supports Dr. Craig and hygiene team at Dr. Abe’s office. So, having everyone together was such a treat!

Day one was all about growth at Finance Camp—learning how to set ourselves up for personal and professional success.

Day two with was incredibly meaningful, especially as we reflected on how far we’ve come since losing everything at our Altadena office from the fires. From finding a multiple temporary locations to starting from scratch, it’s been a challenging road.

Despite the emotional rollercoaster, we’ve been blessed with so much support. This time together helped us focus on gratitude, planning for an exciting future, and improving systems to make patient care in our temporary space seamless. We even ended it with a calming sound bath! Thank you ❤️

Those two days reminded us how thankful we are for our incredible team, our loyal patients, and the chance to continue doing what we love—even during this temporary season. Your trust means everything to us, and we can’t wait for what’s ahead! ❤️

DUE TO THE FIRES AT EATON CANYON, TWENTY28 DENTISTRY WILL BE CLOSED UNTIL FURTHER NOTICE. Our area has been evacuated and our team is safe.

Unfortunately, our office is currently without power, which prevents us from accessing our system to contact patients directly about appointments. We deeply apologize for any inconvenience this may cause.
Once it is safe to return to the office, we will reach out to reschedule all affected appointments.

We appreciate your patience and understanding during this challenging time. Our thoughts and prayers are with the first responders working tirelessly to contain the fires and with everyone affected.

Stay safe, and thank you for your continued support.
