Dr. Silas Sheridan
Dr. Silas Sheridan is an Executive Coach & Clinical Psychologist who helps ambitious leaders think clearly, lead steadily, and remain inwardly strong under pressure. His coaching rests on a framework that is informed by his clinical training: precise assessment of your emotional and leadership patterns, a clear explanation of what actually drives you, and a tailored plan to change the habits, decisions, and internal narratives that shape your work.
High performers rarely fail from lack of intelligence or drive. They fail when anxiety, shame, and old fears drown out their own judgment. Dr. Sheridan helps you see those patterns plainly, then equips you to regulate emotion when it matters most, handle conflict deftly, communicate with authority, and decide from a steady mind instead of a fearful one. The result is clarity about who you are and the grounded excellence that comes with it.
This is coaching for high performers who want rigorous, psychologically-informed work. No hype, no platitudes, just the mental architecture required for sustained, repeatable success.

Dr. Chrystal Marte
Dr. Chrystal Marte is a Clinical Psychologist and Executive Coach who works with high-performing executives, entrepreneurs, and founders across industries operating in high-stakes, high-visibility roles. With deep expertise in clinical psychology and executive development, Dr. Marte integrates psychological awareness with practical, results-oriented coaching. Her work focuses on the internal demands of leadership – emotional control, decision-making under pressure, executive presence, and interpersonal influence.
Dr. Marte partners with accomplished leaders navigating complexity, sustained pressure, team dynamics, career transitions, and the often unspoken isolation that accompanies senior roles. While her clients are already successful, they recognize that unseen internal patterns, blind spots, or workplace dynamics can quietly cap influence and effectiveness. Dr. Marte helps surface and recalibrate these dynamics with precision and discretion.
At senior levels, hard skills fade as the advantage. What distinguishes great leaders is self-awareness, how they lead and influence others, and their capacity to adapt and stay grounded under pressure. Dr. Marte offers highly personalized, confidential coaching designed to create sustainable behavioral change, sharpen leadership development, and support both professional excellence while enhancing well being.
