About Us

Trisian-Global Consulting LLC was established in 1999 by Ada Gresko and has quickly grown to become a highly respected and successful Leadership Coaching and HR Consulting company.  Ada built this consultancy based on one simple belief.  She felt passionately that TGC could stand out from the competition by delivering a positive client experience 100% of the time based on the quality of our services and the power of our results.

We believe that our ability to deliver measurable solutions which exceed expectations is unique in our industry.  Our intense focus on client deliverables is the primary reason why clients return to TGC, year after year.  Human Capital is the single greatest asset that organizations possess, which is why our approach is grounded in understanding our clients' people challenges, and then delivering custom-tailored solutions to solve those challenges.  Our client relationships are predicated on the notion that the better we understand our clients' business - their challenges and goals - the better we can deliver the right solution each and every time.  Many of our clients have been with us since Ada first launched TGC in 1999, because they know we've invested in their success.
