Can someone help me! I am clueless

Hi!
Does anyone know how and where do I need to go to renew my dominican passport, it is more than 40 years old last time I visited DR was a long time ago. I have been a permanent resident all of my life. I have a renewed resident card (5 years old). I need to go and visit and become familiar with the island but can't find out how to go about it. I am not familiar with anyone that speaks spanish let alone a dominican native. As I mentioned I have a permanent resident card.I need a new passport to travel have no interest in becoming a US citizen, almost did during my stint in the Army but for some reason I just rather stay as I was born a Dominican Republic proud citizen, never a USA patriot.I just don't want to alter the status quo of my birth. My parent were both dominican citizens, though my father became a citizen as a young adult. My mom never did, Irespect her for it. Any help will be appreciated and any local help once i get there will also be welcome and handsomely rewarded if need be. thx:surprised

thank you for your help, but is the nearest Consulate in DC or Chicago I am in Columbus, Ohio. Will need to travel, unfortunately I do not have the my parents passports available are they indispensable? do I really need them. I just want to make sure I have everything I need before the trip. I need to go to DR so settle a case of inheritance and will need lawyer and power of attorney, ect., where should I stay in Sto. Dgo without breaking the bank, say for a week. Could you recommend a good lawyer. thank for answering my plight.
