Professional Advisory Services operates as a specialized registered investment advisor focused on providing unbiased research and commentary on specific securities for individual investors and entities formed by them. Founded by Phillip Van Buren, Professional Advisory Services does not manage portfolios, hold custody of client funds, make investment trades, or recommend brokerages. Instead, the firm examines records, financial statements, white papers, and past performance to evaluate growth equities, mutual funds, precious metals, futures, and other assets requested by clients. The firm is strictly a research-based advisory practice designed for small investors who lack the time or knowledge base to conduct deep due diligence on their own investments. Professional Advisory Services does not serve institutional organizations such as insurance companies, pension funds, investment companies, or banks.
