Trainers have produced and published a number of materials and courses that are offered in addition to the Coach Training. Many of these materials are not required for SUN certification. They are offered as additional resources that may be of value to a SUN coach. These are also sold to other coaches and other professionals.

Trainers assume a number of roles in  Success Unlimited Network, LLC

SUN Global Ambassadors form a global network of at least 30 SUN coach volunteers who choose to play a special role in SUN by being involved in the expanding presence of SUN globally as we find ways to be of greater service with our very high-quality, spiritually focused coaching, coach training and mentoring. Examples of Ambassador outreach activities might be to promote the SUN uniqueness by networking with SUN Coaches and Trainers, coordinating presentations at ICF chapters, organizing professional development activities and partnering with regional teams of SUN Coaches for event planning. Each SUN Global Ambassador is linked with a SUN Coach Trainer as a mentor and support.
