Trusted teacher: I am an Italian native speaker and I am fluent in English, having lived a decade in a few different places in the UK. Furthermore I speak Spanish to a beginner-to-intermediate level. I’ve got two passions in life: music and cultures and they both relate to languages. Music is known to be a universal language and different cultures connect with, and influence each other, through the use of spoken language. My formal education lays in music, holding a Bachelor’s degree in Jazz from the Royal Conservatoire of Scotland in Glasgow, and a five-year diploma as a Jazz bass player from the Civica Scuola di Musica Claudio Abbado in Milan. I’ve been teaching music for fifteen years and during the last one I've decided to expand over to languages, by taking up the challenge to combine my passion for teaching with the love for languages. I’ve developed the latter during my many years abroad, where I shared my everyday life with people from all over te world. My method is essentially based on grammar and conversation, alternating the two based on the student’s level of fluency. Once the basics are mastered I focus on conversation, especially providing thorough explanation about typical words and expressions and their various acceptations within different contexts. At times I may also add the odd etymology side note when relevant. I also like to use readings upon subjects that are of the student’s interest, as this aids in nurturing their motivation. Given the transformative and fluid nature of speech, my aim is to deliver an organic learning experience, able to be put to fruition from the start and in everyday life, but that also won’t fail to address the differences between formal and informal interactions. Hence, avoiding inhibit a swift communication in favour of grammatical accuracy. A second level of my teaching focuses on expanding the student's writing skills and this is aimed to individuals who may have achieved a solid grasp of the basis and a wider knowledge on vocabulary. This is because writing is an art on its own and its objective is to convey one's true thoughts and feelings, therefore it requires a dedicated effort. I can teach in English, Italian and Spanish and lessons can be either in person at your place or mine, or via Zoom. Get in touch for more information!

ONE ON ONE PRIVATE YOGA SESSION (California City)
Yogesh
rating star
rating green star
I highly recommend my yoga teacher, Yogesh. He is patient, attentive, and extremely kind. His seriousness and professionalism create an atmosphere of trust and well-being, making each session a true moment of balance and peace. Since I began practicing yoga with him, I have experienced profound changes in myself. Physically, my body has become more flexible, stronger, and more balanced. My tensions have eased, and I feel a new flow of energy in my daily life. On a deeper level, I have learned to breathe better, calm my mind, and discover a serenity I never knew before. His classes have helped me release stress, improve focus, and feel more in harmony with myself. For me, Yoga with Yogesh has become much more than just physical exercise—it is a true life practice that nurtures balance, strength, and inner peace.

PRIVATE COURSES OF FRENCH-FLE ALL LEVELS GIVEN BY PROF PARTICULIER IN BORDEAUX (Bordeaux)
Madeira
rating star
rating green star
I started classes with Madeira in preparation for an interview to a French Medical School. While I had a fairly okay level of French already, Madeira really helped me polish my language skills and achieve the level of refinement and ease in my formal conversational skills which I needed for my interview. She was able to expertly identify what areas I needed to improve upon, and through her exercises and feedback I was able to greatly improve my oral skills. Madeira was also incredibly receptive to any requests that I had regarding things which I wanted to work on, and she went above and beyond in helping me understand technical portions of French grammar with which I have always had issues. Overall, I strongly recommend Madeira as a French teacher to anyone attempting to improve on their French skills.

Private lessons to learn French language and culture (Nice)
Lorette
rating star
rating green star
Lorette was great! In Nice with my daughter who is taking AP French in Seattle. Lorette met us at a local cafe and quickly narrowed in on my daughter (and my) level of French competency. She struck a nice balance of correcting mistakes and allowing the conversation to flow naturally. By the end of the day she had followed up via email with some exercises and grammar resources that were relevant to our lesson. Highly recommend Lorette if you're in Nice (or looking for a great French tutor online). We would likely continue with her online were it not for the 9 hour timezone difference. Merci beaucoup Lorette!
