Get to Know Your Partners In Financial Planning

Our Seasoned Team

We're heavily invested in our team. It is our most valuable resource and is completely focused on delivering the highest quality services and results to our clients.

Castleview Partners was formed in 2015 by Douglas Gill, Umberto Perez, and Michael Mansur, three veteran independent financial advisors who pooled their deep investment, financial planning and technology systems knowledge, as well as their broad financial services industry experience. Key additions to the team include David Fajardo (Director of Capital Markets),  Scott Zachary (Director of Investment Management) and Matt Marquis (Chicago Office Director).  All are financial services veterans. 

By combining and integrating the skills, resources, contacts, knowledge bases and assets under management of all of these key players at the firm, we have been able to achieve three important objectives at Castleview. First, we have built economies of scale, driving costs down for our firm and our clients, and also giving us marketplace credibility and access to strategies that are not available to smaller firms. Second, we have put together an outstanding suite of back office/ support systems to provide a leading-edge technology and operations platform for the firm; and we have similarly assembled an attractive investment platform of best-of-breed strategies for our clients, using an open architecture approach to investing. Third, by organizing ourselves as an independent Registered Investment Adviser, we have ensured that we will continue to be able to advise our clients with integrity and objectivity, as fiduciaries, something which is very important to all of us.

Douglas Gill, CFP®

Partner & Chief Executive Officer 


Prior to forming Castleview Partners, LLC in 2015, Mr. Gill previously founded Argentus Partners, LLC in 2001. During Mr. Gill's 13 year tenure as CEO of Argentus, the firm grew to more than 30 staff members and delivered technology, back-office and asset management services to more than $2.0 billion of client assets for independent advisors across the U.S.

Doug began his professional career with a Dallas-based hedge fund and then moved to New York to pursue equities trading on an institutional trade desk and the floor of the NYSE. Mr. Gill later returned to Dallas and joined a full-service financial advisory firm, Perryman Financial Advisory, in 1990 as an associate, becoming a shareholder/principal in the firm in 1997. He then formed Gill Capital Management, Inc. in 1999 to focus exclusively on improving after-tax investment results for affluent individuals and institutional clients. Mr. Gill brings extensive portfolio management experience to his clients, including options trading strategies, technical analysis and broad knowledge of global macro investment trends.

Past president of the Dallas/Ft. Worth Society of Certified Financial Planners in 1998, Doug was then involved with the financial profession at the national level as a member of the Financial Planning Association's Ethics Committee and served on the Institute of Certified Financial Planners' Committee on Practice Standards. He has often been quoted in the national and local financial media.

A graduate of the U.S. Marine Corps Officer Candidates School, in 1990 Doug earned a B.S. degree in Economics and a B.A. degree in Philosophy from Southern Methodist University.  Continuing his professional education, he earned the mark of CERTIFIED FINANCIAL PLANNER™ (CFP®) in 1994. Doug has previously held several FINRA licenses, including Series 7, 24 and 63 licenses. A lifelong resident of Dallas, he is married with four children and serves as an elder in the Presbyterian Church. He is also a past president of the Rotary Club of Park Cities.

Founding Partner

Umberto Perez, CFP®

Founding partner


Umberto Perez brings over 19 years of experience in the financial planning industry to our firm and, with technical expertise, he utilizes his knowledge in investment, retirement and estate planning to connect with clients. Since the beginning of his career, he has undertaken extensive professional training and continues to develop his expertise in the industry. As a CERTIFIED FINANCIAL PLANNER™ (CFP®), Umberto dedicates his practice to the design and implementation of customized financial strategies for individuals, businesses and foundations. He is committed to delivering personalized service, cutting-edge solutions and comprehensive asset management to those he works with. Umberto is currently registered in 9 different states and holds FINRA Series 6, 7 and 66 certifications. He is also licensed and well-versed in the areas of Life, Health and Annuities.

Prior to entering the financial planning profession, Umberto worked at the Capital Bank of Florida. His experience there served as an introduction to the broader world of financial markets and helped form his interest in financial advisory services. Following his tenure at the bank, he was recruited by MassMutual Financial Group in 1999, where he assisted clients with their financial goals as an investment advisor. Umberto later joined Guardian Life and Park Avenue Securities in 2003 as a registered representative focusing exclusively on improving after-tax investment results for affluent individuals. 

Throughout his career, Umberto has maintained a philosophy of providing clients with objectivity and ethical financial advice. Over time and with experience, he has learned that this can only be accomplished as an independent financial planner, not compromised or limited to the platform and products of any one financial institution. With this in mind, Umberto founded his independent financial planning firm, with the purpose of creating an Open Architectural Platform for his investment and insurance strategies. This advantage has allowed him to remain in the forefront by introducing broad-based innovative investment solutions with a truly unbiased opinion. 

Umberto holds a bachelor’s degree in business administration with a double major in international business and marketing from Florida International University. He has been quoted in numerous articles and has lectured at local universities, as well as associations and charitable events. Umby, as he is known to his friends, and his wife, Neyda, reside in Coral Gables, Florida with their sons, Brandon and Brody, and daughter, Demi.
