“…In summary, my colleague is outstanding in change management and relationship management. His expertise in these areas has had a positive impact on our team and the organization as a whole. I am confident that his ability to navigate through change and build strong relationships will continue to be an invaluable asset in the future. He is truly an inspiration to us all.”
Porya Khorshid - Business Development, Swedish Public Employment Service
Mats and I worked together on the Leadership Team in his capacity as Global Change Manager (OEM). I was impressed by his leadership knowledge, transferable skills and depth of experience with change and process management. Mats knows all of the pitfalls and challenges to drive a successful change management programme and, most importantly, how to make it stick. More than that, though, his strategic view of leadership and holistic approach to business prioritisation makes him stand out, as does his capability to deliver in a fast-paced, distributed global business undergoing exponential growth. Aside from his professional qualities, Mats is a great guy, smart, personable and assured. I am grateful for our conversations and his insight during our time working together. I hope to have an opportunity to work with him again in the future and have no hesitation in recommending him.
Mark Welland - Key Account Manager UK, Niteco

Mats is a true professional through and through. He brings deep expertise on how organisations work and how they can be improved. On top of that, he is a really nice guy. It was very easy to work with Mats, and we had many rewarding discussions around leadership, change management and other business-related topics.
Knowledgeable, dependable, self-managed and will get stuff done. I can recommend Mats wholeheartedly to anyone considering working with him in any situation.

Mikael Nordenstjerna - CEO SE, Niteco

I know Mats as my manager in a development team at the Swedish Public Employment Service during 2019-2021. He has excellent people skills and is able to see the big picture as well as dig deep into specifics when asked. Mats trusted me to get my work done yet I never felt left to my own devices. Trust but verify I suppose would fit the description nicely. I would gladly work with Mats again and can absolutely recommend him in a management and development position.

Mats is a competent, devoted, and inspiring Manager at Ericsson. I have worked with him and his different teams several times, and I am always surprised by the positive and useful feedback he gets from his subordinates. If you get the option of employing him or working together with him, don´t hesitate… go for it!!!

Mats is also a great mentor in both career and life aspects. He always generously shares new ideas about life and career and how we can manage those from different perspectives.

If I ever should have the possibility to work with him again, I shouldn’t hesitate to join his team! I recommend Mats at the warmest!

He is good at making the right decisions at the right time. He is very interested in providing a good working environment for his team, which has led to good results over time. He’s a very motivating person with a good sense of humour and excellent knowledge within the financial field.

As a business colleague to Mats in Saudi Arabia and the United Arab Emirates, I have seen him dealing extremely professionally with many difficult issues in a multicultural and insecure environment. He is sharp and highly competent in processes and financial day-to-day work, to the point in discussions, and he is very human in his approach to the people he manages and towards his colleagues.

Mats is not like a Manager; he is like your best friend when you work with him. He always follows the cooperative process and is one of the process people who must keep the company policy and core values and always think about the company’s benefit first. Apart from this, as a person, he is a good father as he keeps his personal life separate and takes care of his family even though with his busy schedule. I strongly recommend Mats to anyone looking for a manager to run the organization, such as financial control, SSC, or any service-providing organization. I wish him good luck and await another opportunity to work with him to learn more about his leadership & management skills from Mats.

Mats is a driven person who is enthusiastic about work and achieving results on time, every time. He is structured and very good at and interested in motivating personnel. These characteristics make him a good manager who is easy and fun to work with.

Susan Kreivi - Process Expert, Ericsson AB
Mats managed the global implementation of Ericsson’s invoice scanning and workflow solution for local companies and market units. He performed the task with determination and stamina and delivered according to our customer’s expectations and demands. Needless to say, the results increased administrative efficiency while decreasing the total cost for our local companies and Market Units.
Marco-Antonio Morales - Implementation Area Manager, Ericsson AB
Mats is a very experienced guy in Finance, both from his career within Ericsson and earlier within SAAB. He also possesses the international aspect as he has been working as an expat for Ericsson in Saudi Arabia. As a person, Mats is very straightforward with no room for “bullshit” but keeps a very professional attitude about his work relations. I would definitely recommend Mats as a big asset for any organization.

– is a skilled presenter and loves to be on stage; communication with individuals and large groups is a definite strong point
– is a visionary and shaper: an inspires groups and people to meet long-term goals

– delivers results
On a more personal note, Mats qualifies as perhaps the best manager I have had during my 13 years at Ericsson. He has been a fantastic support to me and my development.
I wish to give him my absolute warmest recommendations!
George Grabecz - Project Manager, Ericsson AB
Mats has an eye for the “big picture” and is loyal to the overall mission and strategy of the Group. He is keen on methods and tools to improve the operation at hand, and seems to enjoy especially project-oriented assignments.
Anders Beckius - Global management of Ericsson's Shared Services Centers, Ericsson AB
Mats is a Manager you can trust. He is the kind of person you really look up to. He has an extremely high educational level and strong leadership skills—a perfect manager to inspire you!
Jones Hedlund - Contact Center agent, Ericsson AB
Mats is a very good manager as he really cares about his employees and really encourages people to come up with new ideas for improvements.
Another very positive thing is that he wants people to develop personally and professionally. He also is very dedicated to building a strong team that has a high-performance
capacity.
Carl Niss-Fahlander - Controller, Ericsson AB
Mats was my manager for about two years at Contact Center Stockholm. It was really challenging to be a part of Mats’ team, in a good way! He really focuses on the individual and the team. This means that you need to work with yourself a lot, work with giving and receiving feedback (positive/“negative”), how you express yourself, your feelings, from your point of view, no matter what anybody else thinks. No one can say what you feel is wrong. 🙂
I have received feedback from people saying they think I have been more confident, more tolerant (listen to people and have time for them), etc. This is very nice to hear, and I think it was thanks to Mats. Now, when I don’t work with him anymore, I need to continue this work on my own because I want to keep developing the skills I have. Thank you, Mats, and good luck in the future. I’m sure we’ll meet again!
Sanna Hill - Global Contact Center, Ericsson AB
Mats was a key person during the work to make a global network of internal Contact Centers. As manager of the “template” Contact Center, he was developing all the best practices in processes, tools, and organizational set-up. And all that with a remarkable people-oriented management style. Personally, I knew Mats was a social and always passionate personality – very energetic and inspirational to be around. With a diverse set of experiences, I believe Mats is a person to engage in anything that takes this “extra passion” to get done.
Jesper Pedersen - Manager of Global Financial Support & Process Management, Ericsson AB
I would like to thank you for our contact. I appreciate our conversation when you told me about your job and your view of leadership. It actually gave me a boost and direction! I found it most interesting. I am looking forward to working in an organization like ST, multinational and with great opportunities for growth and development. I look forward to doing a similar “journey” like you have! Once again, thank you. I look forward to meeting again!
Kristi Ekelöw - Consultant Manager, Ericsson AB
I worked with Mats on the STM side in implementing ST-Ericsson’s centralization of account payable activity to the STM ESAS group of Swedish companies.
Thanks to our hard work and the big experience of Mats, a strong team has been created, and after the first phase of the start-up in which we faced a lot of difficulties, the job has been well completed, and now it is going quite well. Thank you very much, Mats
Pierpaolo Poli - COO AP, Ericsson AB
Mats is the kind of leader who gives his employees the opportunity to grow in their roles and responsibilities so that they can be the right person in the right place. With his tremendous amount of experience in leading and coaching people, he ensures that goals are met, recognizes the successes and provides feedback with the sole purpose of learning and improving, realizing that their internal motivation is increasing. In the period that I reported to him, I got to know him as an open, honest and direct person. A person with whom you at any time could reflect your ideas and visions. In times when our surroundings are demanding for each individual, leaders like Mats are needed to keep a team motivated, focused and empowered. It has been really a pleasure to work with Mats. I would recommend him at any time, and if I am given the opportunity to work with him again, I would do that without any doubt
Steve Hehanussa - Project Manager, Ericsson AB
During the 12 years that I have known Mats, I have seen him in various roles: manager, colleague, partner, and supplier/consultant to my own company, “Live Systems Sweden AB.” Mats has been extremely professional and equally proficient in all of these roles.
Mats is an inspirational leader who spreads a positive spirit and can get the group to achieve the same goals, empower staff and get them to burn for their duties. Mats shared his knowledge unselfishly as a colleague, supported his colleagues in their projects and contributed to the “we-feeling”, which was strengthened in the group. In our relationship, the customer-supplier/consultant (to my own company, “Live Systems Sweden AB”) professionally performed Mats assignments, delivered with exceptional quality within the agreed time. The presentation that he created for our company and presented to more than three hundred customers became a real success! He demonstrates exceptional communication skills and is a talented orator. Mats creates more value in every project he works on, solves problems easily, apply analytical thinking. Mats has great drive and accomplishes his tasks and responsibilities best. I would like to endorse Mats and give him my best recommendations.
Lola Vukicevic Rytkönen - CEO, Ericsson AB

Mats is a very seasoned and effective senior manager that really goes for the real goal and delivers. Mats experience makes him a very effective change leader.

Mikael Björn - Business Unit Director, Subset AB
I’ve worked with Mats within the line organization of ITTE Hub Stockholm for 1 year. I’ve seen Mats as a very professional and innovative manager who supported the working group and created a very healthy working environment. My recommendation is for the dedication and motivation shown during the project activities that he has been working with.
Hani Hamdi - ICT Operational Manager, Ericsson AB

Mats have been very easy to work as a line manager, he enjoys in the role and is very clear in the distribution of duties and responsibilities. Mats have a unique ability to simply but clearly demonstrate the significant elements so that all participants understand, he is also sensitive to the views that show up and take NECESSARY into account these.

Luz Lopez - Project Manager, Ericsson AB
Mats put energy into building up our team and letting us think, change, and act independently or within the team. He “plants a seed” in our minds and allows us to work with the idea at an individual pace.
At first, you feel that nothing happened, but after a while, you understand that ideas/changes/problems are something you, as a team member, can handle yourself or within the team. Mats are in the background and support/coach you when needed.
Robert Gouffrich - Project Manager, Ericsson AB
Mats has made a great contribution to the organization with dedication and innovation. As a manager, he is very kind and considerate, encouraging and supporting his staff. It has been a great pleasure to work with Mats from both a professional and a personal perspective!
Bing Lu Runesson - Project Manager, Ericsson AB
Mats has adopted the new leadership model as a coach and mentor. He gives the employees a lot of feedback on getting results and has a clear strategic vision. Proactiveness and support are two cornerstones that can summarize his work right now.
Göran Owe - Program Manager, Ericsson AB
Mats was my manager for 1 year at Ericsson. During this time, I got to know Mats as a manager who was very supportive; he made sure that his team always had what was needed to get their work done on time with the right quality and cost. But more than being just a good manager, I found Mats to be that rare type of person who focuses on what is best for the overall business and the company, even if it means sacrificing his own goals. Integrity is probably the best word I would use to describe him, as he wasn’t afraid to say what needed to be said and do what needed to be done. Working with a manager who didn’t mind going against “big company politics” for the overall business to succeed was extremely refreshing. I would highly recommend Mats as an asset to any business and would be glad to work alongside him again. Please feel free to contact me if you have any questions about Mats.
