The office is beautiful and clean and everyone is very professional and kind. My son was nervous since it was his first time, but they made sure he had a good experience and finish the cleaning. We will be going here for many years to come!"- Noelle "We love treehouse pediatric dentistry. My daughter is 5 and is always so excited for her visits. Last time she was there she asked if she could schedule another appointment next week because she didn't want to wait 6 months. Everyone is extremely friendly and most importantly they explain everything they are doing to my daughter so she knows what to expect."‍- Cara

I will sum up my experience as follows: My rather high needs 15 month old kicked and cried when we had to leave Treehouse because he was so happy there! I had been dreading this appointment because my little guy let’s NO ONE in his mouth, but Dr. Nasem and her super sweet assistant Sadie (I believe was her name), were so kind, fun, patient, and absolutely incredible with children, that he let them do their thing with extremely minimal fuss. This is also notable because he had juuuust fallen asleep for his nap of the day 10 minutes before we arrived, and even being woken up for it he sailed through. This office is gorgeous, sparkling new, immaculately clean, completely state of the art, and has flat screens adhered to the ceiling so your little one can watch during exams. Gorgeous murals have been painted on the walls, and overall it just feels like this very warm, beautiful, magical Disneyland-like place that feels incredibly upscale and not tacky. They are also so nice and bring “treasures” for your wee one to make it fun and enticing to be there (balloon! Rubber ducky! More!). Dr. Nasem is as brilliant and thorough as she is kind. I am thrilled to have my son in her care.

This dentist is amazing especially if you have kids who get anxious and freak out at the dentist. They are so patient and just amazing with kids. My son still gets anxiety going to the dentist but looks forward to coming here and they are so good at taking him through the appointment!

Dr Nasem and her staff are beyond. Beyond amazing. They are truly the kindest people. So gentle with the kids. They make everyone comfortable. Going in with my 3 is a piece of cake (ages 7, 4, and 3). Nothing but praise for this group!

Long story, short, my 5 year old nephew was visiting from the Midwest for the month and needed to go to the dentist. I do not know the first thing about where to take a 5 year for dental work, having never had a kid. Then I remembered meeting Dr Nasem through a mutual friend and gave Treehouse pediatric a ring. They were super friendly helping setup an appointment and get my nephew in the door. Upon arriving, I was blown away by the decor and the kid friendly atmosphere. Everything went so smoothly and the entire experience couldn't have been better. If you have a child in the area I would 100% recommend making an appointment. You won't regret it. Thanks Dr Nasem! You rock!

I love this place. I have a 4 year old autistic girl who is afraid of people, and specially people getting inside her mouth. And everyone in here is so patient. They take all the time needed to create a safe connection with her. There was one time she wasn’t cooperating and even after about an hour or trying to clean her teeth, she wouldn’t let them, so they offered me to split the appointment in 2 appointments, so they could continue later, when she was more emotionally regulated. I don’t think most places would do this.
