Periodontal Associates Team

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!

The 3D scan of my mouth and inner bone structure was a pleasant experience realizing we found other things needing to be done to keep my teeth and gums even healthier! Thank you for this recent consultation and let's keep things moving forward Periodintal Associates staff and Dr. Brett.

I was referred to Dr Thousand by another dentist for a consultation for a full arch replacement. He was very thorough and knowledgeable. This type of treatment is a huge disruption in life so I am waiting for the best time to move forward. Dr Thousand also treated me for a salivary gland blockage. He was very familiar with the problem and performed flawless surgery that completely resolved the problem. I am very confident in Dr Thousand’s oral surgery skill.

I go to Dr. Thousand for periodontal cleanings. He hasn’t really done any other dental work for me, but I really like this practice. He did refer me to a really good dentist for a crown that I needed to have done
