Prospects and insights: Welcome to Siller Immobilien!

REAL ESTATE

On a solid foundation: Our history

Is it the grandfather who’s to blame? Rebecca Siller might have founded a completely different kind of company, had her grandfather not been a successful building contractor. Albeit unknowingly, he significantly contributed to the creation of Siller Immobilien. His entrepreneurial spirit is still present – as much as his sense of social responsibility.

In 2013, Siller Immobilien was founded by the 23-year-old Rebecca Siller. Soon after, the first staff member joined her.

In the following years, the company continuously grew, covering more and more aspects of the real estate sector. Today, Siller Immobilien GmbH offers specialists and contacts for any questions and issues surrounding real estate.

In 2020, we surpassed ourselves: In the course of just one eventful year, Siller Immobilien CH GmbH was founded with several offices across Switzerland.

What about the future? You can stop by any time again and see for yourself how our story continues!

CLARITY

To us, transparency means that each step is crystal clear for you.

The second matter dear to our hearts

A wise person once said: “You never lose by being too generous.” True to this motto, we regularly host events in order to help others, and we donate money to support people and organisations – especially around Christmas. We simply want to share some of the success we have. And what’s better than bringing joy to other people?

Founder, owner, and your point of contact for all matters relating to real estate in Germany, Switzerland, and France.
With her sharp business acumen and social commitment, she leads the company. She is always seeking new challenges while keeping an open ear for her clients and team members. Let her enthusiasm inspire you!

Ronja Holz

Ronja Holz gives properties personality. During her three-year degree program with us, she earned her qualification as a Certified Real Estate Manager (Diplom Immobilienwirtin) as well as a Bachelor of Arts (B.A.) in Management, and today works as a real estate agent with in-depth expertise and a special instinct for people and impact.

Her passion for photography and marketing is evident in every detail. She sees not only what a property is, but what it could be — and how it should feel. That is precisely what makes the difference.

With great sensitivity, a trained eye, and genuine dedication, she has a talent for presenting properties and people in an authentic light. She gives every property a stage and ensures that emotions are created that truly connect.

Ronja is a central part of our team because she makes visible what others often overlook. She brings together heart, creativity, and expression — turning properties into real stories.

David Laniado

When it comes to special properties such as farmsteads, equestrian facilities, and agricultural estates, David Laniado is right in his element. As a qualified equestrian farm manager and trained real estate agent, he knows this world from first-hand experience and combines practical expertise with in-depth professional knowledge.

He does not simply sell properties — he recognizes their potential, understands how they are used, and sees what they could become. That is precisely what makes him so valuable to his clients.

With his open and positive nature, he builds trust immediately. He listens attentively, understands individual needs, and does everything in his power to find the right solution for every situation.

David does not just guide sales processes — he connects people with places that truly suit them. With professional expertise, sensitivity, and genuine passion.

Leni Thomas

Leni Thomas stands for ambition, reliability, and a clear focus on the real estate industry. Already after successfully completing her Abitur, she knew exactly which path she wanted to take — and has been pursuing her goals with impressive determination ever since.

As a trainee real estate specialist, she brings not only a strong professional interest but also a high level of conscientiousness to all property-related tasks. She gets up to speed on new topics quickly, thinks proactively, and stays with a task until it is completed thoroughly and to a high standard.

When it comes to real estate, she demonstrates a strong understanding of processes, details, and interconnections. She is continuously developing and building solid expertise step by step.

For her young age, she is a true gem with great potential — and a valuable asset to our team on real estate projects.

Janina Jahn

Janina Jahn combines expertise, structure, and creativity with a keen sense for people and properties. With her background in International Management with a focus on HR as well as her qualification as a certified business coach, she brings clarity to processes and development.

Within the team, she ensures organization and oversight — and knows exactly where to step in to keep real estate projects running efficiently and successfully.

As the head of our Real Estate Academy, she loves sharing knowledge and supporting people in their growth. At the same time, she understands how to position properties effectively and reach the right audience through the right marketing.

Janina creates structure, distills ideas to their essence, and turns potential into visible results.

Kim Laura Wisotzki

Kim Laura Wisotzki is our strong connection to Switzerland — and much more than just a point of contact. With her training as a dental administrative assistant, her experience as a practice manager, and her qualification as a real estate agent in Switzerland, she combines professional expertise with exceptional organizational talent.

She works with impressive speed, yet never loses sight of what truly matters. Kim knows exactly what she wants, thinks ahead, and manages to handle even complex topics with clarity and structure.

Particularly in the demanding Swiss market, she brings the composure, reliability, and precision that build trust. At the same time, she meets people at eye level, listens carefully, and ensures that clients feel understood and exceptionally well looked after.

Kim is an indispensable part of our team because she does not just organize — she connects. With heart, clarity, and a high standard of quality, she turns collaboration into genuine reliability.
