    Proudly Greek, European & Jewish

    Founded by Dr. Marius Lazar in Greece because he had found the love of his life there, LCG was later acquired and has become a part of the Jewish Seideman(n) family dynasty, with Marius and his own team still on board. The HQ is in central Athen, regional offices are to be found in Luxembourg, Bucharest and Madrid: LCG is a proud Jewish-Greek institution in the European Union.

    Educating the next generation

    Teaching medicine on three continents in many different fields and settings. The focus is on 'rare diseases', an area for which we care passionately. Some member of LCG and the Seideman Group are active supporters of the Jewish University (JUC), the only higher messianic Jewish educational institution globally.

    Rare disease experts

    We are running the only international network practice, LAZAR | SEIDEMAN | SMITH, for the treatment of rare neurologic, neuroendocrinologic, and neurometabolic conditions. The international network practice offers 51 longterm treatment places in cooperation with local partners worldwide. In addition, it helps an average of another 400 to 600 colleagues worldwide with the treatment of rare diseases through medical consultations.

    The Seideman Medical Group

    A global network

    The Seidemann(s), the second "n" is a transliteration issue caused by the authorities of some countries, are a cosmopolitan family, small but with a long tradition line in the fields medicine, art, and patronage. We are liberal Jews, messianic Jews, some converted to other religions, or became agnostics. However, we believe in behavior and results only, not labels or politics.

     

    We are connected by heritage and love, with relatives on every continent except Antarctica. But even that can change, because a true Seideman knows only the limits of ethics and morality. The rest can and should be explored. This website is for contacting those Seidemans who have found their mission in medicine.

     

    It was prompted by the 2022 takeover of the Lazar Medical Consortium Group by the Seideman Group and some long-time partners, some of whom wish to introduce themselves publicly, others not.

     

    "Being a Seideman means never leaving someone behind."

  • Proud to endorse

    The Jewish University


    The Jewish University (JUC) in Denver, CO, is the only messianic Jewish institution of higher education. It's been a proud and fully independent institution since 1980. However, LCG Seideman grants JUC to use the international Lazar | Seideman | Smith network-practice as its clinical teaching center.

    isn't it true?

     

     

    “He who has health has hope; and he who has hope, has everything.”

    – Thomas Carlyle

  • Health @ LCG

    for the forgotten ones with rare diseases.

     

     

    The Lazar Medical Consortium Group (LCG) run by the Seideman family and Dr. Marius Lazar is an association (Art. 78 GR CV) which coordinates the activities of its members and represents them to the outside world. It serves as a "single point of contact" that facilitates contact with the ramified network of projects run by Dr. Marius Lazar and/or the Seideman family. Unlike its members, the LCG association itself is not active in any form of medical, teaching and/or entrepreneurial activities.

    Network

     

    The digital world has greatly changed medicine, as well as teaching, research, etc. - Dr. Marius Lazar recognized this at an early stage and has since acted more quickly and flexibly in medicine, social commitment, but also in research and teaching through his networks. In addition, he has always included other colleagues in his consortium who would not have dared to take the step into the digital world without his digital expertise.

    Why a reorganization?

     

    A reorganization did never take place, and none is planned. What will be changed in the fall of 2022 is the external presentation, so that everyone can understand more easily and quickly what the LCG members do and how to reach them. Since all LCG members are medical professionals, this is managed by PlusOne Media as the communications service provider of LCG.

  • Welcome to LCG Research

    LCG Research is the grassroots research department of the Seideman Medical Group

  • Why LCG Research is needed

     From Clinicians for clinicians.

    Fast spread of new findings using latest technology

     

    We believe that important discoveries in medicine progress far too slowly from the researcher to everyday life of clinicians around the globe. Therefore, LCG Research was established under the leadership of Dr. Carolina Diamandis and Professor Dr. Seideman. The main difference to other research institutions, besides the lack of pursuit of profit, is the focus on publications on digital academic channels and collaborations with independent researchers worldwide.

     

    Peer-to-peer learning is a mutual learning and training strategy that involves participants of the same level engaging in collaborative learning. It can provide an opportunity for learners to share and discuss diverse perspectives, leading to a more well-rounded understanding of the topic. Benefits of peer-to-peer learning include increased engagement and performance, as well as the ability to learn new skills and knowledge.
