"I was provided a list of coaches. . . . Jyllian’s resume immediately stuck out. I was impressed by her authenticity, passion, interpersonal skills, and adaptability. She struck me as someone who would not only meet me where I was but also guide me to where I wanted to go. So, I chose her. . . and I am so glad I did! 

I’m surprised by how much we were able to accomplish over such a short period of time: Producing quality and timely deliverables despite resource constraints; Navigating shifting priorities and unclear expectations from leadership; Juggling both front line supervisory duties and middle management duties at the same time; How to make immediate inroads as a new manager with your team; Empowering and building capacity in staff, especially with my Team Lead; How to appropriately, tactfully, and respectfully push back against directives from leadership that you disagree with 

It was truly a privilege and a joy to be coached by Jyllian. I walk away from this experience with a much deeper understanding of myself and what motivates me, a renewed appreciation of public service, a more optimistic outlook on how to navigate challenges and ultimately a better leader. I highly recommend Jyllian as a coach—she will meet you where you are and help guide you to where you want to go!”

L. Davis Flagg

“Working with Jyllian has been a great experience for my professional growth. Before our sessions, I struggled with clarity and focus on my work goals, often feeling overwhelmed by day-to-day tasks. Jyllian helped me break down my goals into actionable steps and guided me in creating a clear roadmap to achieve them. Through insightful questions and supportive coaching, she helped me build the confidence to take decisive action on key projects that had been stuck in limbo. As a result, I’ve become more proactive, strategic, and effective in my role. I highly recommend Jyllian to anyone looking to elevate their professional impact and unlock their full potential.”

“While participating in a coaching program with Mrs. Jyllian Clarke, she helped me identify areas that needed improvement and encouraged me, when necessary. Her coaching and development methods were very proactive and positive which helped me improve in areas of communication, mentorship and collaboration. While identifying some relevant competency areas, she provided alternative perspectives when viewing situations which allowed me to see things differently. Learning how to become an effective leader and mentor requires various skillsets and she provided ways to develop measurable success goals to improve on those skills. During our coaching sessions, Mrs. Clarke’s approach helped me to delve deeper into who I am and I will forever be grateful for the ways she was able to help me improve.”

Renee Williams

 "Working with Jyllian was an eye-opening experience. Prior to our leadership coaching, I thought I was a strategic 'out-side of the box' thinker who had goals and was unwilling to focus attention on anything outside of what I thought was the pathway to achieve my goals (i.e., tunnel vision). She opened my eyes to leadership skills and opportunities that I had been suppressing and keeping myself 'inside of the box'. I always thought of myself as a technical professional, now I understand that I am a utility player and have the insight and skillsets to influence my organization beyond technical skills."

Richard Dillahunt

"Working with Jyllian has been one of the most transformative experiences of my life! As a young woman who had little guidance in truly understanding myself, her coaching has helped me embrace my authenticity and step into my confidence with purpose and clarity. Through her warm, intuitive, and insightful approach, I’ve learned to recognize my passion, strengths, weaknesses, and triggers, and to use each of them as tools for growth. What stands out most about Jyllian is her incredible attentiveness—she notices the subtle things, like my body language or emotional reactions, that even I wasn’t aware of. Those moments made me feel seen, understood, and genuinely supported throughout our sessions. She creates a safe, empowering space where you feel both understood and challenged to grow. Her coaching has impacted both my personal and professional life, empowering me to walk into every room with certainty about who I am."

Dayna Durrant
