Rosemary began her coaching journey in 2017, when she initiated the idea of an in-house coaching program in the regional office of a federal agency.  The program trained 8 coaches who each coached 2-3 employees.  During the 12 weeks of the pilot program, the culture of the office was visibly changing with improved communication and collaboration.  Rosemary was completely sold on the concept of coaching.  Almost immediately after establishing her practice, Rosemary turned to coaching professionals with ADHD because this is where she saw the greatest need and, let’s face it, Neuro-Atypicals are more fun!  

Rosemary is the parent of two sons with ADHD. As soon as they were diagnosed, she read everything she could on ADHD and was amazed to learn that what she always accepted as “normal” wasn’t considered “normal,” and that her world was full of people dealing with the challenges of ADHD.  Despite what the experts were saying at the time, she realized that ADHD challenges didn’t end upon high school graduation and that many of the lawyers she was supervising were struggling with the same issues.  She started by adapting the strategies teachers were using in the classroom to the workplace and got good results. She originally started her ADDCA training to improve her skills and got hooked on the ADDCA approach. Using the knowledge she gained at ADDCA, she encourages her clients to experiment with strategies custom designed to deal with their challenges while building on their strengths.  

Rosemary supports her clients to:

• Learn to recognize and accept how their unique brain works.  Using a skiing analogy, she points out that skis (and snowboards) are designed to turn in a certain way.  If you fight your skis, it’s ugly (and you could get hurt).  But if you work with your skis, it’s amazing.  Same thing with the ADHD brain.  It’s designed to work in a certain way, stop fighting it, work with it, and do amazing things.  
• Build executive function skills that support all areas of life including planning, prioritizing, procrastination, social skills, time management and emotional regulation.
• Align their personal values and strengths to their professional and personal life. A career path that doesn’t align with the client’s values is like wearing a pair of shoes that don’t fit.  No matter how good it looks from the outside, you’re always in pain. 

Rosemary facilitates a group for Lawyers with ADHD which uses group coaching techniques combined with mentoring and mutual support.    

She is a member of the following organizations:

• Attention Deficit Disorder Association (ADDA)
• Children and Adults with Attention-Deficit/Hyperactivity Disorder (CHADD)
• International Coaching Federation (ICF)
• ADHD Coaches Organization (ACO)
• Rotary International 

Rosemary lives with her husband, a dog and a cat on Bainbridge Island, Washington, except during ski season when they all become snowbirds and migrate to Utah for sunshine and snow. Over the years, the Hollingers have hosted 15 exchange students from 10 countries.  This experience has given her a close-up view of the challenges of adapting to US culture. She is a graduate of Loyola University of Chicago (BA), Georgetown University Law Center (JD) and DePaul University (MS).  When she practiced law, she saw herself as a trial lawyer, mentor and an educator.  Now she is embracing her new identity as a coach, mentor and educator.

Kristen Denney, ACCG, PCAC, PCC

ADDCA Assessor

Washington, United States

Kristen’s journey into ADHD coaching began when she sought a career change. She began working with a career coach who understood ADHD, which helped her clarify her goals and values and inspired her to become a coach herself.

Later, working with her own ADHD coach gave her the support she had long needed, deepening her understanding of how coaching could transform her approach to life and work. These experiences shaped her passion for helping others find the insight that leads to lasting change.

Kristen’s mission is to help ADHD clients live authentically and to guide future coaches in creating meaningful growth and understanding for the ADHD community.

Kristen has expanded into mentor coaching to support other ADHD coaches in their professional growth and ICF accreditation. She once found the ICF competencies and PAAC Essentials daunting, but now genuinely values the structure, clarity, and the way they highlight the distinction between coaching and other helping professions.

She mentors with empathy, patience, and perspective, helping coaches connect the competencies and essentials to their own coaching style.

As a coach, Kristen works with clients ready for change, open to trying new approaches and tailoring strategies to their lives rather than forcing methods that aren’t a good fit.

Her ideal clients are curious ADHDers who want to align their choices with what matters most to them, whether pursuing new career opportunities, building businesses, or creating more ease in daily life, by focusing on strengths, celebrating progress, and fostering self-compassion.

Before coaching, Kristen’s need for freedom and flexibility led her to work as a freelancer, a natural fit for her ADHD. She balanced freelancing with raising her daughter as a single parent, making parenting a priority.

Receiving an ADHD diagnosis later in life gave Kristen clarity about how she had managed her work and family responsibilities. She now appreciates that her ADHD wiring not only presented challenges but also enabled her to innovate, adapt, and juggle competing demands, strengths she now brings to her coaching and mentor coaching.

Kristen splits her time between Seattle, where her roots run deep, and San Diego, where the sun and sense of well-being have become her refuge.
