The Six Pillars of TMS Solutions

The following strengths support the foundation our company was built upon.

Executive Team

Chris Website Circle

Christopher M. Blackburn
Co-Founder & Chief Executive Officer

While charting an innovative business development path with Dr. Sammons, Chris' path quickly turned into a super highway of advocacy for their TMS patients.  

Chris graduated from Gonzaga University where he was a NCAA Division I athlete and was in the US Men's Soccer National Team pool from 1988-1991. Both while at Gonzaga, and following graduation, he worked for the US Government, eventually becoming a front-line, intelligence source during the Balkan wars, for which he received several commendations and International accolades. Chris is currently participating in the Wharton Entrepreneur program.

Chris' mission in life is public awareness about depression and getting relief for depression sufferers. He is a fierce patient advocate, championing for TMS treatment coverage with insurance companies. The driving force behind his work is seeing patients' lives transformed in front of his eyes, despite years and even decades of suffering with depression. He is diligently working to offer TMS Therapy to as many forward thinking doctors and clinics as possible. 

His greatest accomplishments and loves are his kids.

Tim Circle

Tim Denniston
Chief Operating Officer

Tim Denniston attended Gonzaga University from 1989 -1993. He was a scholarship athlete and four-year starter on the men’s soccer team. While working toward his degree, Tim worked as an undergraduate research assistant, studying the effects of extra-cellular conditions on cytoplasmic streaming in amoeba proteus. He graduated as a member of the Honor’s Program, cum laude, with a BS in Biology and a minor in Psychology.

Following graduation, Tim moved to Salt Lake City, UT where he accepted a job at the University of Utah’s Biology Department. There he worked on a cancer research project, studying a vacuole inheritance gene defect in the yeast strain saccharomyces cerevisiae.

Life changes took him back to Spokane in 1995 and in a new career direction. He worked in the hospitality industry, managing several local establishments, including the iconic Steam Plant, where he served as the General Manager for over a decade.

A desire for a new, more meaningful career, led Tim to TMS Solutions.

Dr. Sammons has been added as an adjunct research professor at Colorado Mesa University to develop and publish research and clinical trial information using TMS and Neurostar technology. He is hopeful that TMS will be approved for treating other conditions.

In 2014, Dr. Sammons and Christopher Blackburn co-founded TMS Solutions with the goal of expanding the availability of transcranial magnetic stimulation for the treatment of depression. They are actively seeking strategic partnerships with like-minded doctors and clinics to work with them in this life-changing process.
