J’ai été soigné par Madame Selz pour un lumbago aigu. Le résultat a été très positif en 9 séances . Je remercie cette thérapeute pour la qualité et l’excellence des soins reçus ainsi que pour son écoute vis à vis du patient .

Approche à l'humain tout en finesse et douceur, des massages qui nous laissent en grand bien-être autant le corps que l'esprit. Son expérience et savoir faire en fait un thérapeute que je conseille vivement !!

Professionnelle, bienveillante, à l’écoute, je ne peux que recommander Madame Keltoum Desbeaumes, qui nous accueille dans un cocon apaisant.
