| Factors Affecting Performance [Text Block] | How did the Fund perform in the last year? During the period from July 2023 to June 2024, the DF Dent Premier Growth Fund underperformed its benchmark, the S&P 500. This underperformance was influenced by both sector allocation and stock selection. Notably, the Consumer Discretionary sector contributed positively to the portfolio's performance while the Health Care sector and Information Technology sector detracted significantly from performance. The Fund experienced fluctuating performance relative to the S&P 500, starting with a decline in the third quarter of 2023, followed by a gain in the fourth quarter of 2023, and then facing consecutive declines in the first and second quarters of 2024. Initially, the underperformance in the third quarter of 2023 was driven by negative stock selection and sector allocation effects, but the Fund rebounded in the fourth quarter with positive contributions from both stock selection and sector allocation. However, this recovery was short-lived as both stock selection and sector allocation continued to detract from performance in 2024. The Communication Services sector and Information Technology sector were the largest contributors to the benchmark’s return. In the Fund, the Communication Services sector underperformed driven by a negative sector allocation impact partially offset by positive stock selection in the sector. Similarly, the Information Technology sector also underperformed in the portfolio, where both sector allocation and stock selection negatively impacted the performance. Despite all sectors contributing positively to the benchmark's performance, Real Estate and Utilities were the relative laggards. Top Contributors Amazon.com, Inc. TransDigm Group, Inc.

| Factors Affecting Performance [Text Block] | How did the Fund perform in the last year? During the period from July 2023 to June 2024, the DF Dent Midcap Growth Fund underperformed both of its benchmarks, the Russell 2500 Index and the Russell Midcap Growth Index. The underperformance relative to the Russell 2500 Index was primarily driven by a negative sector allocation effect and to a lesser extent, a negative stock selection effect. Notably, the Information Technology sector and Materials sector positively contributed to the portfolio's performance. This was offset by performance in the Consumer Discretionary sector, Financials sector, and Health Care sector. Energy was the top performing sector for the Russell 2500 benchmark. The Fund's lack of exposure to the Energy sector, resulted in a negative total effect on the portfolio. The sectors that detracted most from the benchmark's performance were Communication Services and Health Care. In contrast, the Fund's allocation to Communication Services positively contributed to the portfolio, unlike the Fund's exposure to the Health Care sector, a laggard in the benchmark, which adversely affected its performance, both with negative allocation and stock selection effects. The underperformance relative to the Russell Midcap Growth Index was primarily driven by both stock selection and sector allocation. The largest detractors from performance were the Financials sector and Consumer Discretionary sector. Utilities and Financials were the top performing sectors of the Russell Midcap Growth Index. The Fund's lack of exposure to the Utilities sector was a minor detractor, while stock selection in the Financials sector had a more significant impact on performance. Consumer Staples and Health Care sectors were the worst performing sectors for the benchmark. While the Fund had positive returns in Consumer Staples, both Consumer Staples and Health Care also detracted from the Fund’s performance. Top Contributors Guidewire Software, Inc.

| Factors Affecting Performance [Text Block] | How did the Fund perform in the last year? During the period from July 2023 to June 2024, the DF Dent Midcap Growth Fund underperformed both of its benchmarks, the Russell 2500 Index and the Russell Midcap Growth Index. The underperformance relative to the Russell 2500 Index was primarily driven by a negative sector allocation effect and to a lesser extent, a negative stock selection effect. Notably, the Information Technology sector and Materials sector positively contributed to the portfolio's performance. This was offset by performance in the Consumer Discretionary sector, Financials sector, and Health Care sector. Energy was the top performing sector for the Russell 2500 benchmark. The Fund's lack of exposure to the Energy sector, resulted in a negative total effect on the portfolio. The sectors that detracted most from the benchmark's performance were Communication Services and Health Care. In contrast, the Fund's allocation to Communication Services positively contributed to the portfolio, unlike the Fund's exposure to the Health Care sector, a laggard in the benchmark, which adversely affected its performance, both with negative allocation and stock selection effects. The underperformance relative to the Russell Midcap Growth Index was primarily driven by both stock selection and sector allocation. The largest detractors from performance were the Financials sector and Consumer Discretionary sector. Utilities and Financials were the top performing sectors of the Russell Midcap Growth Index. The Fund's lack of exposure to the Utilities sector was a minor detractor, while stock selection in the Financials sector had a more significant impact on performance. Consumer Staples and Health Care sectors were the worst performing sectors for the benchmark. While the Fund had positive returns in Consumer Staples, both Consumer Staples and Health Care also detracted from the Fund’s performance. Top Contributors Guidewire Software, Inc.

The sectors that detracted most from the benchmark's performance were Utilities and Health Care. In the Fund’s portfolio, Utilities had a positive total effect benefiting from the absence of portfolio allocation in this underperforming sector. Health Care, on the other hand, contributed positively to returns both in stock selection and favorable sector allocation. Top Contributors Guidewire Software, Inc.
