About Dr. Ruth

Expertise Meets Empathy

I am a dual-continent trained dentist with over 21 years of experience. After earning my degree in Amsterdam (ACTA) and completing an advanced 3-year post-graduate program at Columbia University, I practiced in Manhattan for 12 years before bringing my expertise to Harrison, Westchester.

I focus on trust, comfort, and education with every patient. Beyond dentistry, I am the founding president of GiGi’s Playhouse Westchester.

Testimonials

Transforming Lives, One Smile at a Time

★★★★★

“For the last six years my husband and I have been patients of Dr. Ruth Dieleman-Levine. She is highly reliable, honest, precise, and pursues the highest standards. Even more convenient (for us) she is Dutch! We couldn’t be more pleased.”

Lucas and Addy

★★★★★

“We have come twice a year to Dr.Dieleman-Levine for the past 5 years. She is very thorough, and professional. But more importantly, especially with our kids, she is very calm and nice to them. She has built such a good relationship with our 6 year-old daughters that each time, they are excited to go to the dentist!

We definitely recommend her for the whole family.”

“We’ve been seeing Dr. Ruth for at least 5 years now and we are very happy. We’re so happy with her that we even choose to pay more dental insurance rather than switching to someone else.

She’s very attentive, gentle, and honest with us. Highly recommended!”

★★★★★

“Ruth is the most professional dentist I have encountered. She makes you very relaxed and she takes pride in what she does. I really enjoy coming to this dental office.

Ruth is very understanding of the patient’s needs, she also makes you relaxed. She truly is an asset to the dental profession here in NYC, I wish other dentists were like her. I am glad I picked this dental office to work on me.

I have told others if they need dental work to come to Ruth, they won’t be sorry.”

I would recommend her without hesitation.”
