He completed a Rotating Internship at the Toronto East General (now Michael Garron) Hospital and returned to Vancouver to complete a General Surgery Residency (UBC ’93) followed by a Thoracic Surgery Residency (UBC ’95).

Dr Humer’s vision has been to improve access to thoracic surgical care throughout all of British Columbia. He provided General Surgical and solo Thoracic Surgical care to Prince George (1995-1998) and Kamloops (1998-2002). Dr Humer was a provincial leader in developing the British Columbia Programme of Thoracic Surgical Care where four Thoracic Surgical sites were organized: Vancouver, Victoria, Surrey, and Kelowna. In 2003, the Interior Health Thoracic Surgical group (IHTSG) began in Kelowna with Dr Bill Nelems (2003-2013), Dr Andrew Luoma (2003-2021), and Dr Humer (2003-present) providing Thoracic Surgical services to the interior and a significant portion of northern British Columbia. Since 2003, the IHTSG has been a national leader in providing a virtual consulting service that serves more than 75 different communities in the Interior and North of BC plus the Yukon, seeing more than 20,000 patients. Dr Humer has published and presented extensively on the IHTSG Telemedicine programme. This virtual care programme is an example of our IHTSG commitment to equitable access to thoracic surgical services throughout BC.


Dr Humer completed a MA (Professional Communication) from Royal Roads University (’12) with a thesis entitled – Personalized Compassionate Care: An Appreciative Inquiry Exploring the Positive Core of Canadian Health Care.


Dr Humer is currently (2017-to present) the Kelowna General Hospital Surgical Department Head and Perioperative Medical Director providing oversight and leadership to a rapidly growing surgical department of more than 60 surgeons from 10 surgical divisions. He was a founding member of the Canadian Association of Thoracic Surgeons (CATS) in 1997 and has served on the CATS executive. In 2020, Dr Humer received the CATS Distinguished Service Award – In recognition of outstanding contributions to Thoracic Surgery.

Please let me introduce myself as a proud member of the Thoracic surgical team here at Kelowna General Hospital. I grew up in small town Saskatchewan, and after graduation moved on to the University of Saskatchewan where I earned a BSc. (’92), M.D. (‘96), and completed a General surgery residency with an F.R.C.S.C. (2001).


Upon completion of my training in Saskatoon, I moved on to the University of Toronto where I completed my Thoracic surgery training with an extra year of Cardiac surgery, obtaining my F.R.C.S.C. in 2004. I then returned back to Saskatoon to begin a combined General and Thoracic surgical practice for 5 years.


In 2009 we had the opportunity to relocate to the Okanagan and join an exceptional team at KGH. My wife currently practices as a Pediatric Nephrologist, as we happily raise our 5 children in this wonderful community. I look forward to continue to grow and develop our Thoracic surgical service within Interior and Northern Health.
