Thorough, and professional yet friendly team. Music genres of your choice are available in every dental room, for your procedures. Also available in the waiting room. Consultation was detailed and understandable, and goals were outlined clearly for treatment plans. Great two-way conversation exchange to fully capture issues and make assessments & recommendations. Very organized, personable, and responsive all around. Will be well worth the wait to have the doctor handle my procedures herself. Was referred by Dr. Kwok from another great team of professionals at Root Canal Specialists. I already feel I will be very well cared for. Finally.

From what I thought to be a simple tooth ache, I soon learned that the tooth decay under my crown was significant and ultimately either a root canal of the tooth or an implant was required. That was on a Friday. Oh boy! One week from the up coming Sunday I was to begin a one week vacation! They immediately manufactured a new crown in the office, set it temporarily in place and sent me off for a root canal of the tooth that was completed the following morning. And two days later I am to have the crown permanently installed! I will be forever thankful to Dr. Yuvika Raj Kumar and Ashley.

My usual hygienist was unavailable so I met Kirstin and was very impressed and pleased. I was having some back pain and she was very understanding and helpful. Also very professional and efficient. Since my previous hygienist is reducing her hours, I will be quite happy with Kirstin, as I truly am with this entire dental practice.

Today I faced my fear of going to the dentist after some very bad past experiences. The office staff were very kind, welcoming and professional! Jen and Dr. Hekkert were amazing and understanding! Thank you for all you do and for treating me with "kid gloves". This was a very good experience!
