I have known Callum for more than twenty years. He and I met and interacted on projects of mutual interest and he also offered his services to various business ventures I have been involved in. Callum is one of the most dedicated, hardworking and innovative people I’ve had the pleasure of working with in any capacity. He is also compassionate, kind and never misses the opportunity to help others. Callum is the type of person you can count on to keep a cool head in a stressful situation, and his positive attitude is contagious. For these reasons, I believe Callum would be a valuable asset to any organization or individual fortunate enough to work with him.

I’ve known Callum for several years now, including a time when I served as an Advisor to his company. What I liked best about working with and for Callum, is that he was always true to his word. He always followed-up on his commitments even when this meant upsetting some of the team. I have no hesitation in recommending him as a provider or as a partner. What Callum promises, he delivers.

Callum has acted in the capacity as my advisor and facilitator. His capability to execute on a range of different engagements allows him to have the versatility required to take on complex and challenging projects. Over the years he has been a reliable and knowledgeable source of information and is also one of my most trusted partners I work with. I seek his advice on any number of matters on a regular basis.

Throughout the time that I worked with Callum, he proved at all times to be a resourceful and dedicated team member. Often required to work in uncertain environments, for long periods of time on his own, he is a self-starter who was always able to get the job done, and was able to navigate sometimes 'intricate' political environments to achieve the desired result. Throughout my time working with Callum, he always conveyed himself in a professional manner, with the right amount of respect and drive to get the job done. I would without hesitation work with Callum again in the future.

Callum is the ideal tax client - he has a firm understanding of international tax and finance principles, and is able to relate those principles to the short, medium and long-term goals of his business, subsequently communicating his goals clearly. Due to his technical knowledge, understanding of different cultures, and his genial personality, working with Callum is an enjoyable experience and no doubt helps in producing innovative solutions to the wide range of issues local businesses face. Callum is a driven individual, remaining practically-minded and task-oriented without losing sight of the bigger picture.

I have known Callum for over 20 years. He has supported me with market and industry insight, along with facilitating the organization of advisory boards to provide industry intelligence for policy discussions around technology and crypto currency. He is highly adaptable and flexible to a multitude of requirements, and has a broad knowledge base allowing him to connect with people on a range of different levels.

I have known Callum for almost 10 years and have professionally worked with him for about 5 years through two start-up projects where Callum was the founder of one of them. Callum is a very strong entrepreneurial person with great vision and ambition in what he does. Callum would never give-up during the time we worked together, as we had faced many difficulties in human resources, change management and other situations. He would always stay positive at the highest level and successfully led through crisis until the business developed and grew to where they are now. Besides the professional world, I also admire his supportiveness and kindness to friends, and to people who are in need of help. He is very straightforward and is a compassionate leader who has a lot of ideas so everyone is successful together.

Callum is quite simply one of the most influential people I have ever met. It is an understatement that I’ve always been impressed with not only his life experience, but also his integrity, straightforwardness and adaptability. In only a few years he developed into a seasoned entrepreneur and leader with the kind of business savviness that’s only achievable through building success from scratch in difficult environments. He possesses a fundamental insight that the typical strategist will never acquire, and has the kind of character that you won’t find anywhere else. 

Callum is able to execute many roles and functions simultaneously. His skills cover the whole gamut of entrepreneurial and business topics. His worldly experience, coupled with an astute business acumen, gives Callum a unique, globalised edge as one who can excel in difficult-to-navigate markets and political environments.  I would gladly work with Callum again given the opportunity. I recommend you do so as well.

After knowing Callum for 15 years he now serves as my strategic advisor and mentor. Callum’s insight into all aspects of business is extensive, his experience in many different fields has made him indispensable for my business. I would not be where I am today without his knowledge, wisdom and kind heartedness. Callum will play the key role to scale up your business and is an absolute asset to have in your corner.

Without experiencing further year-on-year growth, Callum was able to reposition my vision and business plan from the top to down, whilst restructuring my team and developing strategy. In doing so I was able to free up my team’s time and refocus on cash flow and business growth activities. Callum has a global perspective and facilitated a trade mission to Sri Lanka to forge new alliances and to set-up our offshore team, which has streamlined our service delivery and taken our quality of work to the next level. We are now re-experiencing business growth with happy clients and new opportunities developing. I’d highly recommend Callum to anyone who is feeling stuck in their business or is ready for the next surge of growth.

I knew Callum for few years. He is a very competent and confident professional and has a very good understanding of a variety of cultures. On occasions we have worked on few projects. He is very enthusiastic and creative.

Callum is one of those managers who also naturally serves as an inspiring mentor for the staff. With his background in management, Callum exhibits strong interpersonal skills and a unique capacity for empathy. These qualities most notably translate in his ability to motivate a team to care about its project and be invested in the project’s success. Callum is the go-to person for conflict resolution and problem solving. Though he’s never one to draw attention to himself, Callum’s positive attitude and the respect others feel toward him are palpable.

Callum is a dynamic entrepreneur who can truly accomplish anything he sets his mind to. Having watched Callum grow businesses from their inception to growth stages, I can say that his work ethic, strategic capacity and vision are second to none.

Callum has always been involved with different projects simultaneously, developing & maintaining relationships with a range of people from all corners of the world. Due to his cultural awareness and general knowledge of the world, he has infinity with people from all walks of life. He is an honest, reliable and hard-working professional, which enables him to deliver a high standard of output. I would not hesitate in recommending Callum as a passionate & effective Businessman.

Callum has provided me with exemplary experience, knowledge and guidance at several critical times in my life. His extensive knowledge of Asia and the culture of international business in Asia has delivered him to a particular niche. His well-placed position has allowed him to leverage his network, experience, and knowledge to his client's greatest benefit.
