My Story and Services

Jenn Monahan McDonald is a Financial Advisor and partner of The Horn Group. She has over a decade of experience in the field of finance and has been with Morgan Stanley since 2020.

Jenn is focused on helping families achieve meaningful transfers of values and wealth. She helps craft personalized financial plans that are flexible enough to adapt to life's unexpected challenges while potentially building enduring legacies that extend beyond the next generation. Her rare approach to tax-efficient investment planning stems from years of collaborating with her father, a seasoned entrepreneur and CPA (not practicing at Morgan Stanley). Within The Horn Group, Jenn is a bridge between seasoned investment management and the exceptional service provided by her partners, helping ensure clients benefit from the industry-leading resources of the firm.

Jenn’s journey in wealth management began over 15 years ago, in the aftermath of the Great Financial Crisis—a pivotal time that emphasized the importance of managing market risks. Her career as a regulatory and hedge fund professional in New York City, with roles at Barclays Wealth Management, the National Futures Association, and Alphadyne Asset Management, fueled her passion for client advocacy from within the financial industry.

In 2018, Jenn embraced an entrepreneurial opportunity by joining The Financial Gym, a women-led FinTech start-up, as one of its early-stage hires. Starting as a Level III Certified Financial Trainer, she coached hundreds of clients, helping them navigate their financial journeys. Her role soon expanded to spearheading corporate partnerships, promoting financial wellness and education on a broader scale.

Jenn is a graduate of St. Anthony’s High School in South Huntington, NY and obtained her B.B.A. in Finance from Loyola University Maryland. She completed the prestigious Financial Advisory Associate program at Morgan Stanley. Jenn holds Series 7 and 66 licenses as well as Life, Accident & Health Insurance licenses.

After a decade of living and working in Manhattan, Jenn returned to her Eastern Long Island roots, and currently resides with her husband Kevin on The Great South Bay. Between balancing competitive couples-pickleball with practicing yoga, Jenn proudly supports many local farms (both land & sea) and small businesses, to encourage an environmentally sustainable future for our Island.
