Dipl.-Ing. Matthias Beyer

Matthias Beyer is a graduate engineer in landscape planning (specialising in sustainable tourism) and a trained hotel manager. He has been working as an international consultant for sustainable tourism in Europe, Asia, Africa, Latin America and the Caribbean since 2002 and co-founded mascontour in 2005. Since 2013, he has been the sole owner and managing director of the company. His professional focus in tourism includes in particular strategy & planning, governance & management as well as evaluation & monitoring. Matthias regularly publishes specialist articles and publications on sustainable tourism and has been a lecturer at Bremen University of Applied Sciences since 2008. He speaks German (mother tongue), English and Spanish.

For me, mascontour is the daily chance to think realities differently in order to set new impulses in global tourism.

  • Certification as sustainability manager (2021-2024) with TÜV Rheinland recognised qualification
  • Certified quality coach “ServiceQualität Deutschland”, German Seminar for Tourism
  • Qualification with “Certificate in Sustainable Tourism” and accreditation as GSTC trainer, Global Sustainable Tourism Council

He likes tourism so much that he often forgets to go on holiday himself. But when he travels, he likes to try out local dishes and finds it exciting to interact closely with local people. He only got his driver’s licence at the age of 32, but manages well without his own car. Matthias loves mixing cocktails, dancing salsa and having long breakfasts in cafés at weekends.

Dipl.-Geogr. Thomas Frommhold

Consultant (Freelance)

Thomas Frommhold holds a degree in geography (specialising in spatial development and tourism). After graduating, he initially worked for the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH in the field of tourism. Since 2008 he has been working as an international consultant for sustainable tourism and as part of the mascontour team he has managed and implemented various projects at home and abroad. His regional focus is on Eastern and South Eastern Europe. His professional focus in tourism includes in particular strategy & planning, governance & management as well as evaluation & monitoring. Thomas speaks German (mother tongue) and English.

For me, mascontour is the opportunity to implement my personal values in my job as well. In addition, the team that works here is by far the friendliest and most competent that I have ever had the privilege of being part of.

Thomas is an active volunteer on the board of GATE – Netzwerk, Tourismus, Kultur e.V. and a member of the German Association for Applied Geography (DVAG).

Thomas caught the travel bug early on. As a teenager, he travelled all over Europe by train every summer to discover new countries. His desire for authentic travel experiences continues to this day – whether it’s staying in small guesthouses and holiday homes typical of the country or shopping at local markets. Thomas also has a soft spot for lists, be they Excel, to-do or shopping lists. Flexibility and spontaneity are not neglected, however, not least thanks to his young son.

Diana Körner M.Sc.

Consultant (Freelance), East Africa Representative Office

Diana Körner studied Tourism Management and holds a Master's degree in Strategic Tourism Management. After various positions in the hotel industry, she worked in the coordination office of the Global Partnership for Sustainable Tourism (UNEP). Diana has been working as an international consultant for sustainable tourism since 2012 and was responsible for various projects in Eastern Europe, Latin America and Africa as part of the mascontour team. Her professional focus in tourism includes in particular marketing & PR, strategy & planning (especially in island states and protected areas) as well as training & qualification. Diana speaks German (mother tongue), English, French and Spanish.

For me, mascontour is a network of like-minded team players who are professionally committed to sustainable tourism.

  • Official trainer on the “Global Sustainable Tourism Criteria” of the GSTC Sustainable Tourism Training Program

Diana is a co-founder of the Seychelles Sustainable Tourism Foundation (SSTF) and an active board member of Linking Tourism & Conservation (LT&C). She also supports the private marine reserve and ecolodge Chumbe Island Coral Park in Zanzibar.

Diana thinks it’s better to work with a sea view! So it’s no coincidence that she currently lives in the Seychelles, where she loves to spend her weekends snorkelling and hiking. Her small organic garden is now thriving so well that she will probably soon be able to supply the entire neighbourhood with her own fruit and vegetables. So it doesn’t bother anyone when Diana likes to sing along loudly to good music, even though she can rarely remember the exact lyrics.

Maeve O'Brien MBA

Consultant, Asia/Pacific Representative Office

Maeve O'Brien holds an MBA in International Hospitality Management from Cornell University/ESSEC Business School (IMHI) in Paris. She has been living in Asia since 2006 and works not only in projects in the ASEAN, China and Sri Lanka regions, but also in Africa. Her core competences in tourism are policy, strategy and marketing as well as employee activation and entrepreneurship. She has worked with a wide range of international organisations including GIZ, AusAID, MDF, USAID, Irish Aid, New Zealand Aid, LuxDev, ILO, Asia Foundation, UNWTO and WTTC. Maeve speaks English and French.

For me, mascontour is one of the few authentic global companies that offers its customers a sustainable competitive advantage for the benefit of all.

  • Teaching in Higher Education Certificate – Temasek Polytechnic, Singapore including Competency-based Learning / Problem-based Learning / Pedagogy / Curriculum Design
  • Cornell Professional Development Programme (PDP) an der School of Hotel Administration, Cornell University, Ithaca, New York
  • PDP Certificate in Relationship and Frequency Marketing
  • PDP Certificate in Marketing Management

Maeve is passionate about hospitality and tourism education and training, as evidenced by her ongoing advisory role with teachers at the Lao National Institute of Tourism and Hospitality, Vientiane. She has also been a guest lecturer for various organisations throughout the Asia-Pacific region.

When Maeve moved to Asia in 2006, it felt like coming home. Spending time with the locals is her favourite activity. She didn’t think she would end up as the lead singer of the local rock band “The Frogs” in Laos during a project in Hainan or as a singer with a busy pianist in the city centre there.

Anette Seidel M.A.

Consultant (Freelance)

Anette Seidel passed the state examination in geography and sport for secondary schools and has been working as a tourism consultant since 1996. She was employed, among others, at dwif Deutsches Wirtschaftswissenschaftliches Institut für Fremdenverkehr e.V. (now dwif Consulting GmbH) and at ift Freizeit- und Tourismusberatung GmbH. Since 2013, she has managed and implemented various consulting projects in Germany as part of the mascontour team. Her professional focus in tourism includes in particular development & planning, governance & management as well as marketing & PR with a specialisation in sales. She has also been a lecturer at the University for Sustainable Development Eberswalde since 2008. Anette speaks German (mother tongue) and English.

For me, mascontour is a fascinating network of creative and open-minded people who, through their work in tourism, can make a contribution to preserving a world worth living in for future generations.

  • Qualification with certificate “Tourism Management and Tourism Planning”, Scharnow Institute for Tourism, FU Berlin
  • Abschluss mit Zertifikat “Tourismusmanagement und Tourismusplanung”, Scharnow-Institut für Tourismus, FU Berlin

Anette is the chairperson of the parents’ association of the Waldschule Gerdes e.V. in Berlin-Zehlendorf. She initiates, organises and coordinates important tasks there at the interface between the school management, the board and the parents. She is also the treasurer of the kindergarten EKT Schlachtensee e.V.

Anette has also found an essential part of her vocation with her profession and her work. She wrote “Eternal traveller” as her career aspiration in her final school newspaper. Although the radius for her projects and private travels has become somewhat smaller since she started a family with three girls, her curiosity and desire to experience new things and actively shape change have grown even more with her children. Anette is postponing the topics of rest and relaxation for now.

Hendrik Wintjen

Consultant (Freelance)

After completing a commercial apprenticeship, Hendrik Wintjen began his career in tourism in Costa Rica and managed an incoming agency there for several years. This is where his interest in sustainable tourism arose early on, which he was able to develop concretely in his next professional stage in a development policy context (CIM/GIZ) as the managing director of a tourism association. After several years focusing on destination marketing in a public-private partnership, he worked as a tourism consultant for the Dutch Development Cooperation (SNV) in Peru. Back in Germany, since 2010 his consulting work at mascontour has focused not only on Latin America but also on other regions of the world, in particular Eastern and Southern Europe, Africa and Asia. He is particularly interested in the topic of market access, which includes governance and market research in addition to classic destination management and marketing/PR. Besides his mother tongue German, Hendrik speaks English and Spanish.

For me, mascontour means working in an interdisciplinary team that can meet the diverse requirements of a multicultural clientele in a globalized world in a flexible and differentiated manner.

  • Trained assessor and coach for the sustainability seal TourCert
  • Graduate of the EKS management course (Energo-Cybernetic Strategy)
  • Additional qualifications in project management

Hendrik is a member of GATE – Netzwerk, Tourismus, Kultur e.V. and of StrategieForum e.V. – Netzwerk für Erfolg und Wachstum.

Several long-term stays abroad – in the USA, Costa Rica and Peru – were formative stations, as was the cooperation with other world regions from Germany. His intensive involvement with different cultures has strengthened his conviction that every culture and every person creates a subjective image of reality in order to construct their own “reality” from it. The best way to philosophise about this with Hendrik is to stroll through a local market.
