Since 1994, our mission has been to create a vibrant, inclusive community on Treasure Island.

One Treasure Island is committed to fostering and stewarding an equitable, inclusive, and thriving community for all Treasure Island residents, employees, businesses, and visitors. Lower-income households and those who have experienced homelessness are at the center of our mission.

With core values such as community, collaboration, and equality, One Treasure Island partners with those that live and work here to create room for every voice to be heard.

Together, as the Island develops, we will champion integration and access to opportunities within the broader, mixed-income neighborhood. From our community center to our signature education programs, we help our residents achieve stability and new opportunity through our integrated programs.


New Name, Same Passion

One Treasure Island, formerly known as The Treasure Island Homeless Development Initiative (TIHDI, pronounced “tie-dye”), launched its new name in 2018 and continues to work as an advocate for all people. 

One Treasure Island's over arching goal is to build a new San Francisco neighborhood that includes formerly homeless and low income people from the ground up and to develop an integrated & healthy community comprised of people from all socioeconomic backgrounds. This has been true for today and is the plan for tomorrow.

I’m ready to learn, do new things, and reach my goals. I’ve learned to appreciate life, people and my freedom.
— Paul Winters, Sanitation Training Pilot Program Graduate

Paul’s Story: Paul is one of six One Treasure Island’s recent STP Commercial B License Training graduates. Paul, formally incarcerated, is ready to begin his new life out the system and ready to achieve his goals. An opportunity rose as he found the Commercial B License Training Program. This new direction has allowed him to focus on his goals and enact them. In his words, “I’m ready to learn, do new things, and reach my goals. I’ve learned to appreciate life, people and my freedom. [One Treasure Island] has made me aware of my finances, how to be financially stable and made me enthusiastic in managing my money. [One TI] staff taught us [STP] to persevere and cooperate in any situation, which I appreciate.” Paul is currently studying for his Class B License exam and ready to continue his journey in the workforce.

 I don’t know how I could have successfully completed any of these things on my own.  
— Mike, formerly homeless veteran and now permanent TI resident

In His Own Words:  I am forever grateful for the patience, understanding, support and encouragement that has embraced me here on Treasure Island since I began this journey.  I work extremely close with TIHDI and their staff to accomplish goals I had no idea were achievable. Some of those goals include getting my credit back up to par, addressing my child support arrears,  engaging more within the society;  which helped restore my hope and faith in life’s possibilities,  and just my whole outlook on life in general. I am a former US Marine Corp Service Member, who found himself homeless after a period of time home. Without much hope or contacts, I was introduced to Swords to Plowshares. The introduction could not have come at a more crucial time in my in life, having already been homeless for 5 years.  Through Swords, I was placed in veteran’s supportive housing on Treasure Island and I have been here for the past three years. Every community agency that has been introduced to me, I have benefited from.


I was formerly incarcerated. Now I’m cleaning up my life, became clean and sober. Finally I have some hope in my life to be able to support my family, rather than going from dead end job to dead end job.”  
— Adam, Construction Training Pilot Program Graduate

In His Own Words: I was formerly incarcerated…now I’m cleaning up my life, became clean and sober…I’m learning a new trade. I have a wife and a three year old daughter so finally have some hope in my life to be able to support my family, rather than going from dead end job to dead end job.”  


I was putting an effort into using drugs, today, I’m putting an effort into working a permanent job.
— Gary, Construction Program Participant and TI resident

In His Own Words: I was putting an effort into using drugs, today, I’m putting an effort into working a permanent job. TIHDI taught me how to save money, get a bank account, do interviews, how to dress for an interview…they taught me computer skills, now I can do almost anything on the computer…They have given me the strength to be a better parent. They have given me the tools to be a better parent. 


After struggling with addiction, homelessness and abuse, LaJuana is now living in stable supportive housing on Treasure Island with her family. She also went from knowing very little about using a computer to learning MS Word, MS Excel, emailing and more. After graduating from the ESSI, LaJuana continues to thrive and to further her education.
— LaJuana Tucker, Treasure Island Resident

LuJuana's Story: As a result of her home catching fire, LaJuana lived in “some of the worst places in San Francisco”, until, after 3 and half years of being on wait list, a unit on Treasure Island opened up for her.

After struggling with addiction, homelessness and abuse, LaJuana is now living in stable supportive housing on Treasure Island with her family. With the encouragement of her case manager, LaJuana started using all the resources on the island to help her get her life back in order. One of the biggest challenges she had was addressing identity theft. She enrolled in One Treasure Island’s Economic Self Sufficiency Institute (ESSI) and was able to resolve the identity theft and protect herself from it happening again.

She also went from knowing very little about using a computer to learning MS Word, MS Excel, emailing and more. After graduating from the ESSI, LaJuana continues to thrive and to further her education. And she is going to be a key note speaker at our next ESSI orientation to inspire others with her achievements!
