His family name was Koutsoyiannis (he signed as the Dimos Skaltsas). Dimos Koutsoyiannis later took the surname Kaltsas or Skaltsas, perhaps from the profession of his father who was a sock maker.
From an early age, the insubordinate and tough Skaltsodimos joined the Klepht body of the famous Kontogiannianis of Ypati. Then, he became the main henchman of Tsam-Kalogiros with Goulas and Diakos. When Tsam-Kalogiros fled the area, he became chieftain of the corps. After strengthening his armoured corps, he envisioned to take the Lidoriki armatoliki by force, igniting the reaction of the Κodjabashis. In order to blackmail the armatoliki of Lidoriki, without bowing to Ferhat Bay, he kidnapped and held Crystallo, daughter of Kodjabashi of Kostaritsa, Anagnostis Babalis, for two weeks. He wanted Babalis to mediate between him and the Turkish Administration, in order to give him the Armatoliki, which he finally succeeded. A well-known folk song says:
“In the heart of the fir tree sits Skaltsodimos………..”
Taking the armatoliki, Skaltsodimos shared it with Diakos, taking the “lower area” to Lidoriki for himself and giving Diakos the “upper area” to Artotina, Vardoussia. After a period of 7-8 years, around 1819-1820, there was a definitive rupture between the two, resulting in the departure of Diakos.
With the outbreak of the revolution, Skaltsodimos liberated Lidoriki on March 20, 1821. He then carried out conscription and created a permanent army in the Makrykampos position. He was involved with his armoured corps in all the important battles that took place in Roumeli, such as the operations against Ypati, Vassilika, Kastalia in Delphi, Ambliani, Mousounitsa, Pentagiou, Siege of Messolonghi, Giannitsa. The Battle of Granitsa was also the last battle he fought. Due to the capitulation and declaration of allegiance to Reşid Mehmed Pasha Kiutahi of all the chieftains of Roumeli, Skaltsodimos, in order not to be subjugated, dissolved his armoured corps and passed to Kerpini, Aegion where he died in September 1821.
