Coaching Team

I’m Christa Doty (she/her), and my coaching is rooted in the belief that every person carries a story that shapes their hopes, actions and sense of possibility. I’m endlessly fascinated by the complexity of being human and the meaning we make along the way—the quiet truths, the hopes, the challenges and the moments that shape who we become. I consider it a profound honor to sit with someone, hear their truth and explore what’s emerging for them. Connection, presence and curiosity guide my work. These values led me to earn a master’s degree in social work from the University of Denver in 1997—though my mom would say I’ve been a social worker in spirit for as long as she can remember. 

My career began in child welfare, where I supported children and families through some of their most vulnerable moments. Over time, I moved into supervision and eventually into training the child welfare workforce, discovering how growth and healing are nurtured when people feel seen, respected and trusted to lead their own path. Today, I serve as a senior program associate at Butler, where I also co-direct the Butler Coaching Collaborative and am a faculty member of the Foundations of Coaching and the Academy of Professional Coaching.  

I completed my coaching training with the Co‑Active Training Institute in 2018 and earned the Co-Active Professional Coaching Certification (CPCC). I also hold a Professional Certified Coach (PCC) credential through the International Coaching Federation, am a Certified NeuroTransformational Coach through BEabove Leadership and am a Qualified Administrator of the Intercultural Development Inventory. 

As a coach, I create a warm, grounded space where people can slow down, reconnect with themselves and explore what’s possible. I believe clients hold deep wisdom—sometimes they just need the right questions, reflections or quiet moments of presence to hear it. My approach is rooted in curiosity, respect and honoring the whole person. Outside of work, I live in Denver, just ten miles from my childhood home, with my partner (a first‑grade teacher) and our four‑legged family member. While I love the comfort of my roots, I’m continually energized by travel and new experiences that expand my perspective and deepen my appreciation for how people all over the world live, connect and make meaning. 

Hello, I’m Brenda Lockwood (she/her). My vision as a coach is to be a catalyst for transformation. This means I guide individuals to rediscover hope, embrace possibility and illuminate the path to their fullest, most authentic selves. I believe every person holds a light within, and through compassionate partnership, I help people uncover it, nurture it and let it shine boldly into the world. I value relationships that uplift others through meaningful contribution and champion fairness and kindness as guiding lights in every aspect of life.  

I earned my master’s degree in psychology from St. Mary’s University in Minneapolis, Minnesota. I have a genuine and lifelong curiosity about what motivates and inspires individuals across the lifespan. I have over 35 years of experience working with adults, caregivers, youth and children in a range of advocacy and helping roles, as well as partnering with organizations to build strong, resilient workforces. 

I am a senior program associate at Butler, where I provide coaching, training and learning experience design. I am co-creator, co-director and faculty member of the Academy of Professional Coaching, Butler’s coach education program accredited through the International Coaching Federation. I am a Professional Certified Coach (PCC), as well as a Qualified Administrator (QA) of the Intercultural Development Inventory (IDI®). 

I’m Sommer Purdom (she/her), a senior program associate at Butler and a trauma‑informed professional coach specializing in leadership development, workforce well‑being and systems change. With more than 20 years of experience across state, county and Tribal child welfare systems, I have a deep understanding of how leadership, organizational culture and system conditions shape people’s capacity to lead with integrity and care. A citizen of the Cherokee Nation, I approach my work grounded in relationship, trust and respect for culture, history and lived experience as essential foundations for healing and change. 

My coaching is guided by values of hope, resilience, safety, connection and self‑determination. I partner with leaders and professionals working in complex, high‑stress environments to support leadership that is both effective and humane. Through trauma‑responsive and neuroscience‑informed coaching, I help clients notice how stress and system pressures show up in their leadership, bodies and relationships, and I support them in strengthening their regulation, clarity and choice. Through my coaching I create spaces where autonomy is honored, trust can grow and people feel supported to reconnect with their purpose, build sustainable practices and lead in ways that foster well‑being for themselves, their teams and the systems they serve. 

Hello, I’m Jenn Turvey (she/her). I’m passionate about helping employees and leaders thrive and follow their calling in today’s complex and demanding workplace.  

I came to coaching from working as an organizational development practitioner, supporting teams and cross-functional work groups. To me, coaching felt like an essential next step in deepening the impact of that work.  

As a coach, I bring a big-picture perspective on how organizations function, inviting clients to consider the dynamics within their own organizations as they think about the opportunities and challenges that are emerging for them. 

I am a Certified Integral Coach through New Ventures West and a Professional Certified Coach (PCC) through the International Coaching Federation. I hold a master’s degree in spiritual and religious experience from the University of Chicago Divinity School.  

I live in central Philadelphia. Among my favorite pastimes are dancing and listening to live music, especially jazz.

Hi, I’m Michael Holcombe (he/him). My coaching philosophy is rooted in the belief that the more we know about ourselves, the easier it is to find our path. We each live complex lives with deep, rich histories, and it is easy to get stuck in the challenges we face. As a coach, I strive to create a space for people to show up authentically, share their stories and explore the values and beliefs that inform who they are. I approach coaching with curiosity, compassion and the belief that every person is creative, resourceful and whole.  

My passion for social justice and creating meaningful change motivated me to earn my master’s degree in social work from the University of Denver. Understanding the values and beliefs driving that passion led me to coaching. I completed my coaching training through Butler’s Academy of Professional Coaching, where I became a Trained Professional Coach (TPC). Today, I am a research associate I at Butler. In this role, I provide research and evaluation services, coach through the Butler Coaching Collaborative, facilitate Foundations of Coaching training and provide individual and group debriefs focused on developing intercultural competence as a Qualified Administrator (QA) of the Intercultural Developmental Inventory.

I’m an associate professor at the University of Denver Graduate School of Social Work and a faculty affiliate at Butler. My approach to coaching is grounded in the belief that everyone has a fundamental right to workplace well‑being, meaningful growth and a sense of agency in their work. I love stories and see coaching as a collaborative, strengths‑based process, one where we honor your unique story while also recognizing our shared humanity.  

I have over 15 years of clinical experience, including as a child welfare caseworker with the Los Angeles County Department of Children and Family Services, and I hold an MSW and PhD in social work. I’m a licensed clinical social worker and a Certified Professional Coach through the International Coaching Federation. As a Butler coach, I combine my background in clinical practice, research and workforce development to support reflective, practical learning. Since 2020, I’ve also served as a Faculty Success Program coach with the National Center for Faculty Development & Diversity, where I primarily coach Black, Indigenous and People of Color faculty; I was honored to receive the Faculty Success Program Coach Excellence Award in 2021. 

When you work with me, you can expect thoughtful partnership, honest reflection and tools that support clarity, sustainability and self‑advocacy, whether you’re navigating leadership, career transitions, burnout or institutional challenges. I draw on my experience as a clinician, researcher and leader to help coachees’ build their capacity, amplify their voice and move toward goals that feel both achievable and aligned with their values.
