IMPACT COACHING
At Optimum Impact Coaching, we believe effective leadership development starts with understanding people. Our collective expertise brings together seasoned leaders and experienced coaches with diverse perspectives to tailor coaching to the unique needs of each leader, team, and organization.

Our Story
Optimum Impact Coaching began in 2000 when consulting partners Roberta Fiore-Kittell and Dr. Bonnie Maitlen came together around a shared belief: great coaching is personal, practical, and helps people achieve meaningful results. Roberta brought deep executive coaching and human resources experience, while Bonnie contributed expertise in life planning, leadership development and team coaching, working with leaders and teams around the world.
In 2019, Kevin Logeman joined the team to expand the offering and grow the business, bringing global human resources leadership experience and a passion for helping people and teams perform at their best.
Over time, we've continued to grow our team to better serve the needs of our clients. Sarah Callihan brings expertise in strategy, culture, and organizational change. Megan Davies adds extensive experience in leadership development and career transitions. And Dallas Auvil brings a unique perspective as a physician, psychiatrist, and former healthcare executive.
Today, our collective expertise allows us to work with leaders at different levels, across industries and organizational structures, and through a wide range of challenges and growth opportunities. We take the time to understand each client's needs and connect them with the coach and approach that's the best fit for them.
Vision and Values
Our Vision
We recognize how organizations value their leaders. Our goal is to increase that value exponentially. We believe every leader has strengths and potential worth developing. Our goal is to help leaders recognize those strengths, build on them, and make intentional, sometimes subtle, changes that improve how they lead, work with others, and achieve results.
Through personalized coaching, leadership development, and team effectiveness coaching, we help leaders gain confidence, strengthen their influence, make better decisions, navigate challenges, and contribute greater value to their teams and organizations. By turning personal insights into purposeful action, we help leaders grow in ways that advance their careers, strengthen organizational performance, and create meaningful, lasting impact with powerful positive results.
Our Values
Our work is grounded in trust, integrity, intentionality, and a genuine commitment to helping people succeed. We value the trust and confidence our clients place in our people and our processes and believe that great coaching requires curiosity, mindful and active listening, understanding, healthy boundaries, and respect for each person's unique experiences and perspectives.
Our Coaches
Shared Commitment. Personalized Coaching. Meaningful Impact.
Great coaching starts with the right connection. Our team brings together seasoned executives, credentialed coaches, and diverse industry perspectives to help leaders and organizations navigate complexity, grow with confidence, and achieve meaningful results.
We believe coaching should be as individual as the people we serve. Through our collective expertise and people-first approach, we take the time to understand your goals, challenges, and culture—connecting you with the coach whose experience, perspective, and style best fit your needs.
Together, we help leaders create clarity, strengthen trust and influence, build alignment, and take purposeful action that drives lasting impact.
“I am always amazed at the greatness that is found in every individual I coach. Often, they don't see it until it is brought out through the coaching process. Subtle moves make a difference and I often hear that coaching has been transformational.”
