Our Team

Founded in 2005 by Derek H. Suite, M.D., Full Circle Confidential is a culturally competent, spiritually sensitive, mental performance resource made up of board-certified and licensed mental health experts, executive coaches, and wellness professionals with significant expertise and experience in executive and leadership coaching, peak performance psychology, high stress and anxiety management, and cultural diversity. Our Full Circle team is especially good at helping top performers:

  • Peak under pressure
  • Manage stress and performance anxieties
  • Increase grit, confidence & mental toughness
  • Sustain positive motivation, attitude & energy
  • Master the use of visualization & mental imagery
  • Master focus, execution & decision-making skills
  • Master achieving the appropriate level of arousal
  • Master emotional reactivity and attitude control

Our Approach

Caring. Compassionate. Competent. Confidential. Although our work primarily involves the use of evidence-based treatments within the fields of neuroscience, psychopharmacology and performance psychology, our team is especially sensitive to the need to incorporate cultural and spiritual sensitivity and recognizes that respect for another’s culture and faith is of the utmost importance.

We use a holistic approach — examining the biological, psychological, social, and on occasion, spiritual dimensions of any situation. We are also qualified to provide medication management. In conjunction with traditional modalities, we offer Mindfulness-Based Interventions (MI), where applicable.

Our team is sensitive to the needs, dignity, and rights of our clients. As our name implies, confidentiality is at the heart of all of our work. We are able to travel and see clients at home or in other privacy settings.
