As responsible hospitals and clinics across the country look for ways to reduce their environmental impact, it has made sense to start with the departments that have the largest environmental footprints. The operating room (OR) is one of the largest users of supplies within hospitals and outpatient centers, as well as one of the largest producers of waste. Case studies have demonstrated that between 20-30% of the total waste generated by facilities comes from the OR. A number of leading healthcare institutions like ORA® Oral Surgery & Implant Studio have begun to tackle this problem by identifying a set of best practices – the Greening the Operating Room Initiative.  Greening the OR is a collaborative effort lead by Practice Greenhealth, and it consists of thought leaders from across the health care sector, including representatives of major hospital systems and individual hospitals, health care professional organizations, and pioneering “green” surgeons.

As an extension of Greening the OR, Practice Greenhealth established the Council for Environmentally Responsible Surgery, which is made up of a growing number of forward-thinking surgeons, such as Dr. Steven Koos, who wish to contribute their innovating efforts and ideas to work on greening ORs throughout the country.


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.

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.

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.
