Denise and Louis Joseph are tan, svelte, and naturally blessed with the kind of delicate bone structure plastic surgeons strive and fail to imitate. Heads turn when they enter a room. They could easily be mistaken for luxury brand influencers but for the strange air of kindness, simplicity, and detachment they exude.

Denise and Louis have a way of communicating with you that leaves you feeling genuinely lighter and freer without knowing exactly why. When asked what they think of the effect they have on others, Denise says, “We are not practicing some novelty ASMR. We are living, breathing examples of the OSI-type life. We are our own patient zero.”
What is Open Sea Institute (OSI):
Denise and Louis Joseph are the founders of Open Sea Institute (OSI), the bespoke psychiatry, executive coaching and wellness organization using proprietary, founder-innovated theory and practice to serve a growing elite class of the international business community.
Characterized by invention, expert psychiatry, solid leadership experience, and a facility with sophisticated industry and its players, Open Sea Institute is known to bridge the gap between individual and group psychology and overall corporate performance.
Open Sea Institute has partnered with professional individuals, families, and communities worldwide, from start-ups to mature multinational corporations, on all aspects of high-level organizational management.
Recently, Open Sea Institute’s partnership with the Rolls-Royce RREC was memorialized at an international celebration of the release of “120 Years of Rolls-Royce,” authored by London Press Club Lifetime Achievement Award Winner Ray Massey, commemorating the Rolls-Royce journey of undisputed market domination and all-electric future with the release of the super coupe, Spectre.
Richard Freed, St. James’s House founder and “120 Years of Rolls-Royce” publisher, says: “The committee has selected Open Sea Institute as a partner for the publication marking the 120th anniversary of Rolls-Royce due to the company’s innovative approach. The values and style that characterise OSI’s approach to coaching, psychiatry and health highlight its commitment to excellence, and it will undoubtedly be a major part of this project’s ongoing success.”
Founders’ Stories:
Though founded during the COVID-19 pandemic, Open Sea Institute has rapidly gained a reputation as psychiatry, mental healthcare and executive coaching par excellence. While Open Sea Institute’s debut and acceptance into the international business community have been relatively seamless, the reality is that OSI and its founders, Denise and Louis Joseph, are anything but Denise says, “Open Sea is the culmination of our combined journeys—a patchwork quilt of our rigorous educations, our hard-won experiences, our staggering wake-up calls, even our worldviews and ancient bloodlines. Our own distinct histories and multidimensional oeuvres afford us the ability to co-create with leaders in the upper echelons of finance, tech, government and academia who themselves are often highly complex individuals. For instance, on the most basic level, if you were to ask either one of us where we are from, we’d have a very hard time answering you.”
Open Sea Institute was born from Louis and Denise’s shared disillusion with the financialization and corporatization of mental healthcare. Both Denise and Louis bring shockingly impressive resumes to practice.
Dr. Louis Joseph is a decorated medical doctor and psychiatrist who has worked in leadership positions at some of the world’s premier medical institutions. As his biography will attest, Louis spent his professional years in an array of sectors from finance and leadership to research, public health and medicine.
Dr. Joseph is uniquely equipped to understand the needs of his patients. He has spent years forming care relationships with indigent patients in inner cities, members of the elite, and communities of the differently-abled in rural America.
Whether performing TMS and other somatic procedures on the neuropsychiatry ward, teaching medical students and resident physicians in the academic arena, working Emergency Rooms in disaster zones and underserved areas, providing expert testimony in courts of law, administering novel, life-altering pharmacotherapy to those struggling with substance use, checking in with elderly patients at the nursing home, or manning informational booths at county fairs, Dr. Joseph has enjoyed practicing psychiatry across a multitude of settings with an incredibly diverse patient population.
Just before co-founding OSI, Louis was serving the dual roles of Chairman of Psychiatry and Chairman of Policy and External Affairs within the Mayo Clinic Care Network. As dual Chairman, Dr. Joseph assisted in optimizing underperforming clinical enterprises and assets within the health network in his role as an acting operating partner/interim executive.
Dr. Joseph has even co-founded an insurance company, serving as its Board Chairman and investment committee member. In his spare time as a fine art connoisseur, Dr. Joseph, together with Denise Joseph, served as partner in an art advisory firm where he developed a novel fine art acquisition strategy that has seen successful implementation.
Both Denise and Louis, with their shared backgrounds and passion for fine art, continue their artistic pursuits as avid collectors for the Joseph Family Collection and as sitting council members at the Norton Museum of Art in West Palm Beach, Florida. Though the details are kept private, the Joseph Family Collection is rumored to hold works from Baxter to Rembrandt. At the Norton, Denise and Louis focus their attentions on the acquisition of emerging contemporary artists, often from underprivileged and underrepresented backgrounds.

Meanwhile, Open Sea Institute’s prime mover, Denise Joseph, took unanticipated professional turns in law, high-dollar fundraising, and fine art. She arrived at OSI as an experienced Lawyer, Executive, and Master Certified Professional Coach educated by various elite institutions at home and abroad including The George Washington University, New York University, and Oxford University.
Denise has authored academic works in peer-reviewed publications on the topics of mental health and public policy. As primary founder of Open Sea Institute and chief innovator of proprietary OSI-type technology including OSI-type Coaching and OSI-type Eco Medicine at OSI Sanctuary Sites, she has, in her words, “reimagined and re-executed the science and art of mentality as it has never before been conceptualized.”
Designed for Easy Access, Intended for an International Audience:
Convenient to an intended international audience, OSI-type programming was designed from the start to be, “accessed, privately, anywhere on Earth through secure teleplatform technology.” OSI-type psychiatry, OSI-type coaching and in particular, OSI-type eco-medicine, are practiced at the Open Sea Lodge at Nantahala Water Mountain on the Precambrian Blue Ridge Mountains in the Western Carolinas, and at anchor sites in South Florida, New Orleans and London.
While Denise and Louis happily rotate between OSI-type sites throughout the year, West Palm Beach, home of the infamous Mar-a-Lago Accord, is decidedly home for the Josephs.
The pair reside, private beachfront, on West Palm’s toniest street. Denise, who considers the ocean, “both my neighbor and my mentor,” named OSI for the sea she so loves. “With doctoral and post-graduate degrees in international relations and law, I founded Open Sea Institute to connect people across oceans of difference—physical, cultural, and political,” says Denise. “There is no aspect of my education, training or experience that does not inform my practice at OSI.”
Denise continues, “At Open Sea Institute, Dr. Joseph and I seek to engineer a reality that respects and loves the human individual as the bedrock of civilization. The work I generate is primarily foundational because I know that investment in self is not only investment in the individual, family or community, but investment in nation, in state, in economy and GDP, and in our collective future. I know that societies will truly flourish when mental health is adequately prioritized and incentivized in populations. I designed Open Sea Institute to be a force for good in this world.”
The Future is Bright for Open Sea Institute:
Regarded locally as thought leaders, one Palm Beach source this writer interviewed, notably offered the following: “During the 2024 election cycle, when both parties were between candidates, I heard Louis Joseph’s name mentioned more than once around town as exactly the kind of person we need to lead the country… to restore sanity in America. There’s just something about the guy that seems to appeal to everyone. And you’ve got to admit, he looks Presidential. He just looks and feels like the man for the job.”
Denise, Louis’ partner in life and purpose, is thoughtful when she reads her fellow Palm Beacher’s words saying, “I know that people were talking about him (Louis) during the race because quite a few people made similar statements in front of me. People were disillusioned with the current field of candidates. Many still are. The election went one way and people were devastated. Had the election gone another way, an entirely different set of people would be devastated. Open Sea Institute is fiercely nonpartisan and Louis has never been a political animal. We both registered as Independents at 18, but who knows? I certainly agree with community sentiments about Louis’ potential fitness for presidential office. Louis is a wise and decent and beautiful human in every way that counts. America would be lucky to have him. I know I am.”
Whether on-site or online, Open Sea Institute supports all psychological ailments, including addiction, anxiety, depression, stress, mood and developmental disorders. Clients may also take advantage of OSI-type Coaching in wellness and beauty, addictions and dependencies, executive and corporate development, and family, couples and life transitions.
While Louis and Denise emphasize that all are welcome, Louis cautions, “We are not for the faint of heart. We are for those who truly desire transformational change. It’s best to set expectations upfront.”
And as she is known to do, Denise elegantly concludes our discussion, telling us, “We are committed to nothing less than the elevation of global consciousness.”
