Periodontal Associates

Periodontal Associates was founded in 1974 by Dr. Ken Versman in Aurora, Colorado. Over the decades, the practice became one of the region’s most respected centers for periodontal and implant care.

Dr. Doug Heller joined the Aurora office in 1991, followed by Dr. Eric Beckman in 2012, continuing the founders’ commitment to excellence and patient-centered care. In 2018, Dr. Daniel Thousand joined the team and helped expand the practice by acquiring a well respected periodontal practice of Dr. Paul Glick in Littleton, CO. We later relocated the Littleton office to its present location in a larger, state-of-the-art space in Centennial, CO.

Our Mission and Philosophy

At Periodontal Associates, we partner with patients to achieve optimal oral health through personalized, collaborative, and compassionate care.

We believe every patient plays the leading role in their health journey. Our doctors guide each individual with expertise, transparency, and respect, never rushing treatment decisions or compromising on quality.

As a privately owned practice, we remain independent to ensure that care decisions are always made in the best interest of our patients.

I’ve been working with Dr. Heller regularly for a couple years maybe a few years now. When I first met Dr. Heller, I had gingivitis. My regular dentist referred me to whom he referred to as a “specialist”. My mouth was in such bad shape. I thought I was going to end up with dentures. My gums were purple. They would bleed when I brushed. It would get loose. Dr. Heller said that my teeth were savable. Honestly, I didn’t believe him. I wish I had before and after pictures. I hope they do at Periodontal Associates. Because there’s been a complete transformation of my oral health. My gums used to be purple they’re pink now my gums used to bleed every time I brush my teeth before and now they don’t. I am also a lot happier because I’m not in pain. Also, just a couple days ago I noticed my bank account received $888 for Periodontal rewards. This amount was added to my account by Dr. Heller and everybody at Periodontal Associates. All of the people that work with him are very pleasant and I am very grateful that I met these kind of people. If you ever read this, Dr. Heller, I just wanna say thanks a lot man, you’re awesome, trustworthy, and good at what you do. I couldn’t ask for a better dentist! Because there isn’t a better dentist.

I love my smile! Dr. Beckman is an artist :-). I didn't even know what was possible, but Dr. Beckman did a beautiful job with the crown lengthening, and I healed quickly with no issue. On top of it all, he and his team are warm, personable, and always put me at ease. I also love the beautiful succulent they sent in the mail as a thank you. So thoughtful. I recommend Dr. Beckman and his team without hesitation.

I had an amazing experience with Dr. Thousand and his whole team! After having a pin tuck surgery only 2 years prior with a different periodontist. I was in need of gum surgery again and was absolutely devastated to have to go through another surgery. I found Periodontal Associates through my dentist. I am now 4 weeks post surgery and can’t believe how easy the pre-procedure process went, the actual surgery and recovery was so smooth and my recovery was seamless! They even sent me a cute succulent! 😉 absolutely recommend this team!

    Great checkup experience! Very thorough and pleasant, despite the fact that the hygienist was armed with sharp objects. Easy check in too.

    I had such a great experience with Dr. Beckman! From the moment I walked in, everyone was so kind, welcoming, and professional. I felt comfortable and well taken care of throughout my appointment. Dr. Beckman took the time to listen to my concerns and explain everything in a way that was easy to understand. I really appreciate the care and attention I received. I’m very happy I found Peridontal Associates and would definitely recommend them to family and friends!

    The procedure was clearly went through, answered all of my questions, and laid out cost completely. Procedure went great and there were no surprises. The team was very supportive though out the entire process. I also appreciate the dependability of the team and if they say an appointment will take 5 min, they mean it.
