Steven andNishida
Senior Consultant

A lifelong passion for learning and leadership brought me to Impact, and I couldn't be happier with my decision. As a designer, facilitator, and thought partner, I embrace a scholar-practitioner mindset, running to the issues and engaging others with clarity, empathy, and authenticity. My favorite activity of each day is laughing, playing, and making up bedtime stories with my kids. They're hilarious!

I have spent my career exploring, researching, teaching, coaching and practising leadership skills. I love working with individuals and groups to tackle hurdles and develop strategic initiatives. When I am not designing programs, I like to spend time with my son and my husband building forts out of driftwood or laughing with friends in the beautiful pacific northwest.

An adventurer, I was raised in the UK and have lived and worked in Eastern Europe, Spain and now (since 2012) Asia, where I head up Impact’s Singapore Office. A fierce supporter of the authentic self and advocate for individual growth, I care deeply for my team and clients, wanting them to shine for who they are. I have a keen sense of challenge and adventure, and away from work, you can find me with my young family (usually outdoors!).

Mario andGianAndrea
President and Founder

I’ve been many in my working life: an HR Director, an entrepreneur, a leader, a coach, a salesman, a visionary, a confidant, a manager. And a friend. And I am still excited (and sometimes anxious) when I meet a new group of people. I genuinely enjoy it! This is the reason I'll probably work for another decade! The only difference compared to the past: today I can afford to only work on projects and with people that I really like and that gives me the feeling that it will be great fun!

Senior Consultant

I like to do meaningful work, working together with clients to create something new and deeply valuable. The areas of change where I feel I contribute the most with my skills and strong business background are leadership development and agile transitions. I like to challenge myself in many ways, my favorite challenge is climbing high ice covered mountains.

Sam Rostas, Impact International

Samantha andRostas
Global Lead

After 10 years leading the UK, I am now in a global role focused on two areas: one leading a people project, the other focused on marketing. I grew up through Impact as a marketer and love the buzz of building business through brand and storytelling. My other passion is the people and culture here, so this is the ideal combination for me. When I’m not working, I love spending time with my family, enjoying the outdoors and practicing yoga.

Consultant and Facilitator

As a consultant, I hope to be a catalyst for change, helping others to discover what their real needs are. Empathy, curiosity, creativity, organisation and strong sense of duty are the things that most characterise me. I love the adventure and the discovery of travelling, organising outdoor trips with friends in close contact with nature… But also sharing a gin lemon or a barbecue at home is not so bad!

Senior Consultant, UK

My focus is on developing responsible leadership. I bring a warm combination of broad industry experience, academic rigour, Yorkshire humour and humility. My motivation and purpose is to help us mutually learn and create a more sustainable, compassionate and just world.  Fortunately, my spirited playful side, wilderness adventures and inclination toward anything shallow on a Friday night ensures people still invite me to parties despite all of that.

Senior Consultant

When asked, "What do you do for work?" it is not uncommon for me to respond, "Light Bulb Moment Technician". I have been fortunate to be filled with such energy through my talent, leadership, and organisational development work. When I am not working, I take my role as Aunt Cassie with my husband, Josh, very seriously! It is the greatest thrill to teach them to ride motorcycles, do yoga, and explore the world.
