Eco-friendly limousines? An earth-loving dental spa?
Meet six Chicago businesses you’d never think of as green.

These days in Chicago, everyone from salon owners to limo company VPs — luxury-based business leaders you would never expect to launch headfirst into the pro-environment movement — are taking the stand: Go green, stay glam. And it’s working like a charm (made of metaphorical recycled metals of course)…

Steven Koos, co-founder of the new ORA® Dental Studio, pauses as he walks down the mint-and-tan hallways of his South Loop practice — which, too glamorous for a dentist’s office, boasts features like Energy Star HDTVs in every treatment room. But Dr. Koos is more eager to show off the Demolizer II, a machine that uses dry heat to dispose of medical waste, eliminating the hazardous fumes of incineration. The Northwestern grad has inCorporated countless other green aspects into ORA®, including digital, lead-free X-rays…

Dr. Koos and Kralj will open a Wicker Park studio by early 2010. For Chicago at least, it seems like there are greener days ahead.


  • Dr. Koos was caring and professional.

    Great experience from start to finish. Dr. Koos was caring and professional, making an otherwise uncomfortable experience as pleasant at possible.

  • Pleasantly surprised by post-surgery follow up

    It was a pleasure to have straight forward information provided and constant follow up after my surgery. I was pleasantly surprised to receive a call from Dr. Steven Koos late at night to make sure I was having a healthy recovery. And the cherry on top of the ice cream was how updated the office was. State of the art equipment that I had no doubt I was in good hands.

  • Great place and great staff.

    Great place and great staff. I was well informed about the entire procedure and the follow up process. I also felt very at ease knowing the doctor called me later in the day and him providing me his number in case anything happens.

  • Earns my trust for comfort and care

    I had two implants, a sinus lift and one other procedure within the last year or so. I can’t speak highly enough of Dr. Koos and his staff. I was well informed about my needs and next steps. And more importantly, all went well with very little discomfort. I’m usually a little skiddish when it comes to dental surgery and any associated pain. ORA Oral Surgery & Implant Studio earns my trust for comfort and care.

  • They took great care of me.

    I had an amazing experience. I went in scared and in pain and honestly they took great care of me. I would definitely be going back for any dental need. They are friendly and make you feel at ease.
