Long before their media exposure, the family had already laid the foundations of a strong aesthetic and narrative universe. A signature that, over the years, has evolved into a true brand.<\/p>\n<p>&nbsp;<\/p>\n<h2>The family before the spotlight<\/h2>\n<p>&nbsp;<\/p>\n<p>It all began with <strong>Sandrine and Olivier Kretz<\/strong>, <strong>a couple with no background in real estate<\/strong>. <strong>She was a teacher who also took on interior design projects, while he worked as a sales director in a telecommunications company<\/strong>. Nothing seemed to predestine them to become figures in luxury real estate. In the late 2000s, while searching for their own home near Paris, in Boulogne-Billancourt, they decided to change direction and launched <strong>Kretz &amp; Partners<\/strong>, with a rather bold intuition: to<strong> position themselves directly in the high-end segment<\/strong>, without going through intermediate markets. The company<strong> initially focused on castles before expanding its portfolio to include private mansions, exceptional apartments, and villas.<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p>At the same time, Sandrine played a key role in<strong> international development<\/strong>. Being multilingual, she built <strong>a network of foreign clients, including expatriates, investors, and high-net-worth individuals<\/strong>. Kretz &amp; Partners\u2019 reputation was built discreetly, almost confidentially, within a circle where word of mouth carried more weight than visibility.<\/p>\n<p>&nbsp;<\/p>\n<p>In the <strong>2010s<\/strong>, a turning point came with the <strong>gradual arrival of their four sons &#8211; Martin, Valentin, Louis, and Rapha\u00ebl<\/strong>\u00a0<strong>&#8211; into the business<\/strong>. This integration deeply transformed the structure. Each brought <strong>different skills: business development, strategy, communication, and digital.<\/strong><\/p>\n<p>&nbsp;<\/p>\n<figure id=\"attachment_41553\" aria-describedby=\"caption-attachment-41553\" style=\"width: 1003px\" class=\"wp-caption alignnone\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-41553\" src=\"https:\/\/magazine.luxus-plus.com\/wp-content\/uploads\/2026\/04\/1444x920_entre-challenges-professionnelles-et-vie-professionnelles.webp\" alt=\"\" width=\"1003\" height=\"639\" \/><figcaption id=\"caption-attachment-41553\" class=\"wp-caption-text\"><span style=\"font-weight: 400;\">\u00a9 <\/span>R\u00e9servoir Prod.<\/figcaption><\/figure>\n<p>&nbsp;<\/p>\n<p><a href=\"https:\/\/magazine.luxus-plus.com\/en\/the-agency-the-kretz-family-at-the-heart-of-luxury-real-estate\/\">Click here to read the full article<\/a> on Luxus Magazine.<\/p>\n<p>&nbsp;<\/p>\n<p>Featured photo : DR<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In just a few years, the Kretz family has grown from a low-key agency founded in France in 2007 in Boulogne-Billancourt to a major player in the luxury real estate market, propelled by television exposure and a well-established family strategy.<\/p>\n","protected":false},"author":674,"featured_media":193665,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_titles_title":"%%post_title%% %%sep%% %%sitetitle%%","_seopress_titles_desc":"In just a few years, the Kretz family has gone from a discreet agency to a key player in high-end real estate, driven by television exposure and a well-honed family strategy.","_seopress_robots_index":"","_seopress_robots_follow":"","_seopress_robots_imageindex":"","_seopress_robots_snippet":"","_seopress_robots_primary_cat":"none","_seopress_robots_breadcrumbs":"","_seopress_robots_freeze_modified_date":"","_seopress_robots_custom_modified_date":"","_seopress_robots_canonical":"","_seopress_social_fb_title":"","_seopress_social_fb_desc":"","_seopress_social_fb_img":"","_seopress_social_fb_img_attachment_id":0,"_seopress_social_fb_img_width":0,"_seopress_social_fb_img_height":0,"_seopress_social_twitter_title":"","_seopress_social_twitter_desc":"","_seopress_social_twitter_img":"","_seopress_social_twitter_img_attachment_id":0,"_seopress_social_twitter_img_width":0,"_seopress_social_twitter_img_height":0,"_seopress_redirections_value":"","_seopress_redirections_enabled":"","_seopress_redirections_enabled_regex":"","_seopress_redirections_logged_status":"both","_seopress_redirections_param":"","_seopress_redirections_type":301,"_seopress_analysis_target_kw":"","footnotes":""},"categories":[22488],"tags":[24133,25190,24191],"class_list":["post-193667","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-lifestyle-en","tag-divertissement-en","tag-immobilier-de-prestige-en","tag-luxus-plus-mag-en-2"],"_links":{"self":[{"href":"https:\/\/luxus-plus.com\/en\/wp-json\/wp\/v2\/posts\/193667","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/luxus-plus.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/luxus-plus.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/luxus-plus.com\/en\/wp-json\/wp\/v2\/users\/674"}],"replies":[{"embeddable":true,"href":"https:\/\/luxus-plus.com\/en\/wp-json\/wp\/v2\/comments?post=193667"}],"version-history":[{"count":8,"href":"https:\/\/luxus-plus.com\/en\/wp-json\/wp\/v2\/posts\/193667\/revisions"}],"predecessor-version":[{"id":193760,"href":"https:\/\/luxus-plus.com\/en\/wp-json\/wp\/v2\/posts\/193667\/revisions\/193760"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/luxus-plus.com\/en\/wp-json\/wp\/v2\/media\/193665"}],"wp:attachment":[{"href":"https:\/\/luxus-plus.com\/en\/wp-json\/wp\/v2\/media?parent=193667"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/luxus-plus.com\/en\/wp-json\/wp\/v2\/categories?post=193667"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/luxus-plus.com\/en\/wp-json\/wp\/v2\/tags?post=193667"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
