Joachim of the Queen of Peace was born in Sassello, Province of Savona, Italy, on February 12, 1890, to Giacomo Ramognino and Caterina Badano. He was baptized with the name of James Peter. The father preferred to call him Leo and as such was he registered in the Municipality, in honour of Pope Leo XIII.

After elementary school, his father quickly put him in a workshop to learn the trade of carpenter.  At the age of 17 he was already working in the workshop as the owner. At the age of 25 he took part in the First World War, among the pontieri (bridge maintenance men) of the V Company. He initiated among the soldiers devotion to the Holy Child Jesus of Prague, already known by the Ligurians. In 1918, regardless of the danger from the Piave in flood, Corporal Nino (as he was called, from the ending of his surname and a reference to his devotion to the nino Jesus) with his good pontieri, set to work to give a ride to the troops of the XXII Army Corps who, on the night of October 26, passed over the bridge he had fortified, the only one left viable after the flood. The Child Jesus had passed through their minds, he was carried by "Nino" and his group of "ardent followers". Nino later received the honour of Knight of Vittorio Veneto.

In memory of the gift of peace, our Leo Ramognino, collaborating with the indefatigable Msgr. Pirotto (later bishop of Troy in Foggia) built the Monte Beigua sanctuary in honour of Mary Queen of Peace. A veteran from 1919 onwards, he gave himself body and soul to the building up of his parish. It can be said that he founded the St. Louis Catholic Youth Group. He lived intensely the life of an associate of the Confraternities to which he belonged and of the St. Alfonso Mary de' Liguori Catholic Workers' Society of Mutual Aid. He also cooperated in establishing the Catholic Explorers in Sassello.

The 1950 Holy Year became for Nino a great turning point, the year in which he entered Carmel in the Varazze desert monastery, at the age of 61. He was helped, in particular, by Father Anastasio Ballestrero, then Provincial, who immediately formed a deep friendship with him, based on esteem for his pure soul as a "child of God". In 1967, after ten years as a regular tertiary, from the direct interest of the then Superior General, Fr A. Ballestrero, Br Joachim (religious name he chose), was admitted to Solemn Profession, directly in the First Order, without the canonical year of Novitiate.

Having become a Discalced Carmelite religious, he was put in charge of the Sanctuary of Regina Pacis, in the meantime entrusted to the care of the Discalced Carmelites. He called himself good-naturedly "a poor old sack of flour". The people of Sassello (Acqui Terme), called him and still remember him as "Ninu u santu", that is, Nino the saint. His hope was a characteristic trait. It communicated a luminous certainty. God's love then expressed it in a special way through prayer. He identified himself with God, detached himself from everything, and returned to everyone with more love. It could be said that it was a continuous "thank you" to God and also a thank you to the brothers. Brother Joachim had a smile that we no longer have, and we can no longer have. In him the sky and the beauty and tenderness of the Virgin Mother Mary could be seen to shine through.

He died in the Desert of Varazze on August 25, 1985.

The diocesan inquiry into his "life, virtue and reputation for holiness" closed on January 6, 2015. On 13 May 2016 the decree of validity was granted.
