About Gladbrook

Invest today. Change tomorrow.

Warren Blesofsky launched Gladbrook Investment Group in 2017 in Long Beach, CA. With extensive experience in real estate brokerage, pharmaceutical science, and multiple successful business endeavors, he started Gladbrook with a unique vision: invest in science-led human health and wellbeing solutions.

Gladbrook is building a new paradigm for clients in the medical cannabis sector and an impactful investment strategy for the future.

Investing is changing.
The way we invest is changing faster than ever as global innovation is evolving rapidly.

And yet, what you want hasn’t changed.
You still want security for your future. You still want to feel in control of your investments – now, more than ever. But you also want your investment choices to drive positive change for you and the planet.

The problem: old systems have their own priorities
The sponsors of traditional investing models prioritize their returns ahead of your future. They don’t prioritize your needs like self-direction and positive impact.

The problem: old systems don’t prioritize putting you in control
You have never been the priority in this “old-school” traditional investing system of stocks, bonds, and mutual funds. You’ve never had control. You weren’t able to equally prioritize your values and future security.

The problem: you’re not secure, and you’re not in control
Layers of complexity in the traditional investing infrastructure make it nearly impossible to understand or control your investments without a graduate degree in Economics. This means that venturing into emerging markets exposes you to unnecessary risk.

You might be missing out on the best new investment opportunities!
Traditional investing models can’t leverage the best new opportunities. The people who benefit from the latest opportunities for big returns are professional insiders. You are left picking over the remaining investment “scraps.”

Yes, even in your 401Ks & IRAs.
Today, most funds offered in your retirement plan are diversified in a way that precludes focused attention and single industry expertise. Without awareness and expertise, you can’t navigate emerging markets or manage the risk of investing in trending markets.

If you stick with tradition, you will miss out on promising investments, give up control and involvement, and accept that your money at best is building a world you don’t care about, or at worst, one you don’t want to live in.

The Gladbrook Solution

You need a fresh approach to investing that puts you in control, protects your future, and produces returns while being good for the planet.

With Gladbrook, you aren’t only investing. You are building a legacy.
You are not a professional investor. You don’t have time to watch the stock market by the hour and read the tea leaves to make trades at just the right moment.

You care about long-term results – not short-term gains. You’re not a gambler.

You’re a savvy steward of your retirement!

You are here because you care about building a great future for yourself, your family, and the world around you.

  • You want to be healthy
  • You want to be safe
  • You want to invest in a brighter future

And today, there is a better way.

You no longer have to limit yourself to old-school traditional investing models. The equities market includes stocks, bonds, and mutual funds, which invest in companies that are most likely not aligned with your values.

To build a better future for yourself, your family, it is possible to find investments aligned with what is most important to you.

Gladbrook solves the most critical issue facing the medical cannabis and ESG (environmental, social, and governance Investing) markets. Gladbrook helps these sectors grow, thrive, and positively impact our world by providing investment in these markets.

Warren Blesofsky, Co-Founder & President, Gladbrook Investment Group

Warren has spent his life and career on a mission to improve human health and wellbeing, values he learned from an early age from his parents, both medical professionals.

Warren received a Master’s Degree from UC San Diego in Biochemistry and Cell Biology. At school, he co-authored a published peer-reviewed journal article in biochemistry and cell signal titled Cell Oncogene.

After graduation, he worked in the pharmaceutical industry on research and development for various companies, including Tanabe Research Laboratories and La Jolla Pharmaceuticals. At this time, Warren became interested in cannabis as pharmaceutical medicine, which was early on in scientific development.

Warren was disillusioned working in pharmaceutical medicine and the direction of the scientific community for optimal health. Also, his friendly nature led him out of the lab and into the real estate industry. He helped start a midsize real estate appraisal firm in 2000. Later, Warren became a principal buyer of real estate throughout Southern California.

In 2017, he earned a California Real Estate Broker and Mortgage Originator License passing extensive background checks by the state. Investors have relied on his expertise to seek a return on investment in alternative assets not available in traditional markets. Although he loved working directly with people in real estate, he wasn’t fulfilling his mission of improving our health and wellbeing.

While building his real estate investment business, Warren co-founded the Sklar Center for Restorative Medicine with his mother, Susan Sklar MD, a Harvard-trained OB/GYN surgeon. The Sklar Center for Restorative Medicine, established in 2007, is a premier medical center for anti-aging, hormone balance, brain function, and optimal health in California.

In 2017, Warren set his sight on a new vision – to invest in science-led solutions to improve human health and wellbeing. He launched Gladbrook Investment Group with his real estate and science-led advantage. He created the first product, the Gladbrook Cannabis Holding Fund, a leading vertically integrated investment fund for private investors owned and led by the Gladbrook Management Team.

Susan Sklar, MD

Susan Sklar, MD, opened the Sklar Center for Restorative Medicine in response to the unmet medical needs of men and women in the Long Beach, California, area. When conventional medicine did not address her own and many of her patients’ concerns, she turned to functional medicine and found the answer. As a functional medicine practitioner, Dr. Sklar takes a holistic approach to the body and how its systems work together.

Dr. Sklar is a Harvard-trained gynecologist who spent more than 20 years as a practicing OB/GYN. She started her medical training at the Boston University School of Medicine and served an internship at Boston City Hospital. She completed her obstetrics and gynecology residency at Harvard’s Beth Israel Hospital.

Using the Sklar Center Protocols she designed, she solved her medical problems. Dr. Sklar’s discovery and her personal experience with functional and anti-aging medicine drive her to share this new approach with her community.

Dr. Sklar has joined the Gladbrook team to research and develop new cannabinoid-based therapeutics and formulations utilizing her past 15 years of functional and anti-aging medicine expertise.

Dr. Sklar, MD

“I am honored to join Warren, Ryan, and their pharmaceutical team to develop new cannabinoid-based therapeutics that can help people feel great again and maintain optimal health.”
– Susan Sklar, MD.
