Compensation Actually Paid vs. Total Shareholder Return [Text Block] | The following graph illustrates the level the Total Shareholder return of a $100 investment made in both the Company’s stock and in a proportionately allocated investment in the common stock of the peer group over the five-year time horizon. Additionally, the graph includes the CAP of both the Company’s CEO and the average of the non-CEO NEOs over the five year time horizon. The Company’s TSR compared to the Peer Group TSR. Assuming the theoretical investment of $100 in the Company’s common stock versus a proportionately allocated investment in the common stock of the Peer Group on December 31, 2017 the TSR of the Company’s Common Stock underperformed the TSR of the peer group over the five-year time horizon ending December 31, 2022. However, the TSR on the theoretical investment in the Company’s common stock out-performed that of the peer group over the initial three years, before underperforming the peer group TSR in the final two years of the five-year time-horizon. Management speculates that the outperformance of the Company’s TSR in the initial three-year period may reflect the value investors placed on the Company’s growth in earnings and overall profitability in addition to balance sheet growth in the years leading up to December 31, 2020. Management speculates that the underperformance of the Company’s TSR in 2021 and 2022 is a result of volatility in loan growth and an increase in charge-offs and related provision for credit losses and an increase to the level of non-performing loans in 2022 as a result of the deterioration of a single credit relationship. The PEO and Other NEO’s Compensation Actually Paid to Company’s TSR. Reported, performance-based compensation for the Company’s Named Executive Officers is limited to the Company’s Cash Incentive Plan and Performance Based Restricted Stock, which have no direct link to the Company’s TSR but are indirectly linked to TSR as they are dependent upon financial performance. However, due to the Company’s equity-based compensation of its executive officers, each Named Executive Officer has a substantial amount of unvested restricted stock outstanding at any point in time. Additionally, in 2020 the Company transitioned from the use of stock-options as its primary equity-based compensation vehicle to restricted stock. Each of the NEOs, with the exception of Mr. Boyle, also had unexercised stock options outstanding as of December 31, 2022, as a result of option awards made in 2020 and earlier. Due to significant amounts of outstanding restricted stock and unexercised stock options CAP to each of the NEOs is impacted directly by the changes in fair value of the Company’s common stock. Between 2018 and 2019, CAP to the Company’s CEO and Other NEOs increased, largely as a result of hitting established performance targets and improved TSR experienced by the Company’s common stock in 2019, and the resulting increase in value of unexercised options. In 2020, CAP to both the Company’s CEO and other NEOs increased relative to 2019, despite a negative TSR recognized in 2020. The 2020 increase in CAP despite the negative TSR was a reflection of the Company’s transition from stock options to restricted stock as its primary equity-based compensation vehicle. Upon this transition, the Company provided initial grants for both retention as well as to better align executive interests with those of shareholders. These initial restricted stock grants were made to each of the named executive officers in August 2020 in an amount approximately equal to one year of base compensation with a 5-year vesting period. The decline in CAP in 2021 to both the CEO and other NEOs, despite positive TSR was largely a result of smaller restricted stock awards made in 2021 relative to 2020 although following Mr. Boyle’s hiring in December 2020, he was awarded a restricted stock grant of similar size in March 2021 as the other NEOs received in August 2020. The decline in CAP in 2022 to both the CEO and other NEOs was primarily a result of the decline in the value of the Company’s common stock as reflected in the TSR. As noted above, the Company’s TSR in 2022 underperformed the Peer Group, but in general, valuations of the common stock of publicly traded Banks declined in 2022. The decline in the valuations of bank stocks in 2022 reflected the uncertain economic environment characterized by the general increase in interest rates and the inversion of the yield curve. |  |  |  |
Compensation Actually Paid vs. Net Income [Text Block] | The following graph illustrates the level of the Company’s net income over the five-year time horizon in comparison to the CAP of both the Company’s CEO and the average of the non-CEO NEOs. PEO and Other NEOs’ CAP and the Company’s Net Income. As noted above, CAP of the Company’s NEOs is influenced by the valuation of the Company’s common stock, as a result of each Named Executive Officer having a substantial amount of unvested restricted stock outstanding in addition to unexercised stock options at any point in time. Additionally, the Company has two established mechanisms for compensating executives based on the Company’s financial performance: (i) the cash incentive plan and (ii) performance-based restricted stock grants. The Company’s bonuses paid in March 2023 tied to the 2022 Cash Incentive Plan were tied to established goals for Net Income (70% weighting) Community Reinvestment Act Rating (10% weighting), Return on Average Equity relative to peer (10% weighting) and Return on Average Assets relative to peer (10% weighting). Historically, there has been a strong weighting assigned to the achievement of targeted net income in the payment of bonuses under the cash incentive plan for any given year. Vesting in shares of performance-based restricted stock is based on the Company’s Return on Average Equity relative to peer levels, which is heavily influenced by net income. CAP to the CEO and other NEOs grew in 2019, directionally consistent with growth in income, but this growth in CAP was more of result in the improved valuation of the Company’s common stock as of December 31, 2019 relative to December 31, 2018 than it was a result of growth in net income. CAP of the CEO and other NEOs grew in 2020, despite a slight decline in net income. As noted above the growth in 2020 CAP was primarily a result of the significant restricted stock awards made to the NEOs in August of 2020, as the Company moved from stock options to restricted stock to better align interests of executives with those of shareholders. The decline in CAP in 2021 to the CEO and to other NEOs, relative to 2020, despite record earnings in 2021, was a result of a decline in the size of the restricted stock grants made in 2021, relative to 2020 as outlined earlier. The decline in CAP in 2022 to both the CEO and the other NEOs was primarily a result of a decline in the value of the Company’s common stock as reflected in the TSR for 2022, this decline in the TSR during 2022 was impacted by broad economic conditions but may have also been influenced by a decline in the Company’s earnings, primarily as result of charge-offs and requisite provision expense resulting from the deterioration of a single loan relationship. |  |  |  |
Compensation Actually Paid vs. Company Selected Measure [Text Block] | The following graph illustrates the level of the Company’s ROAE over the five-year time horizon in comparison to the CAP of both the Company’s CEO and the average of the non-CEO NEOs. PEO and Other NEOs’ CAP and the Company’s ROAE. As noted above the fluctuations in the CAP between 2018 and 2022 are largely a result of the valuation of the Company’s common stock as reflected in the TSR, with the spike in 2020 a result of a significant grant of restricted stock in August 2020. However, Management does see a relationship between stock performance and financial performance as reflected in ROAE and maintains that as a result a relationship, albeit indirect, exists between ROAE and CAP. The increase in CAP in 2019 was directionally consistent with the growth in ROAE we reported in 2019. While the growth in CAP was more attributable to the improved valuation of the Company’s common stock as of December 31, 2019 compared to December 31, 2018 that valuation may have been influenced by positive investor sentiment following the improvement in reported ROAE during 2019. During 2020, the Company’s ROAE declined relative to 2019 primarily due to increased provision expense following the onset of the COVID-19 pandemic. The growth in loan balances in 2020 and the related increase to net interest income were not enough to offset the increased provision expense brought about by COVID and 2020 ROAE declined relative to 2019. However, due to the significant initial grant of restricted stock awards made in 2020, as described above to better align executive’s interests with those of shareholders, growth in CAP did not correlate with the decline in ROAE. As economic conditions improved in 2021 and we saw continued strength in the credit of our loan portfolio we released reserves, which benefited earnings and ROAE. At the same time, the valuation of the Company’s stock improved, which influenced CAP. This improved valuation may have been influenced by the Company’s profitability as reflected in the growth in ROAE, but may have also reflected broad investor sentiment due to relatively stable economic conditions. The decline in CAP in 2022 reflects the deterioration in the value of the Company’s stock, which was likely the result of various investor concerns, including; the prospect of reduced future earnings following a series of accelerated Federal Reserve rate hikes in response to historically high inflation levels and the impact of the deterioration of a single significant loan relationship on the Company’s asset quality and earnings. |  |  |  |
Total Shareholder Return Vs Peer Group [Text Block] | The following graph illustrates the level the Total Shareholder return of a $100 investment made in both the Company’s stock and in a proportionately allocated investment in the common stock of the peer group over the five-year time horizon. Additionally, the graph includes the CAP of both the Company’s CEO and the average of the non-CEO NEOs over the five year time horizon. The Company’s TSR compared to the Peer Group TSR. Assuming the theoretical investment of $100 in the Company’s common stock versus a proportionately allocated investment in the common stock of the Peer Group on December 31, 2017 the TSR of the Company’s Common Stock underperformed the TSR of the peer group over the five-year time horizon ending December 31, 2022. However, the TSR on the theoretical investment in the Company’s common stock out-performed that of the peer group over the initial three years, before underperforming the peer group TSR in the final two years of the five-year time-horizon. Management speculates that the outperformance of the Company’s TSR in the initial three-year period may reflect the value investors placed on the Company’s growth in earnings and overall profitability in addition to balance sheet growth in the years leading up to December 31, 2020. Management speculates that the underperformance of the Company’s TSR in 2021 and 2022 is a result of volatility in loan growth and an increase in charge-offs and related provision for credit losses and an increase to the level of non-performing loans in 2022 as a result of the deterioration of a single credit relationship. The PEO and Other NEO’s Compensation Actually Paid to Company’s TSR. Reported, performance-based compensation for the Company’s Named Executive Officers is limited to the Company’s Cash Incentive Plan and Performance Based Restricted Stock, which have no direct link to the Company’s TSR but are indirectly linked to TSR as they are dependent upon financial performance. However, due to the Company’s equity-based compensation of its executive officers, each Named Executive Officer has a substantial amount of unvested restricted stock outstanding at any point in time. Additionally, in 2020 the Company transitioned from the use of stock-options as its primary equity-based compensation vehicle to restricted stock. Each of the NEOs, with the exception of Mr. Boyle, also had unexercised stock options outstanding as of December 31, 2022, as a result of option awards made in 2020 and earlier. Due to significant amounts of outstanding restricted stock and unexercised stock options CAP to each of the NEOs is impacted directly by the changes in fair value of the Company’s common stock. Between 2018 and 2019, CAP to the Company’s CEO and Other NEOs increased, largely as a result of hitting established performance targets and improved TSR experienced by the Company’s common stock in 2019, and the resulting increase in value of unexercised options. In 2020, CAP to both the Company’s CEO and other NEOs increased relative to 2019, despite a negative TSR recognized in 2020. The 2020 increase in CAP despite the negative TSR was a reflection of the Company’s transition from stock options to restricted stock as its primary equity-based compensation vehicle. Upon this transition, the Company provided initial grants for both retention as well as to better align executive interests with those of shareholders. These initial restricted stock grants were made to each of the named executive officers in August 2020 in an amount approximately equal to one year of base compensation with a 5-year vesting period. The decline in CAP in 2021 to both the CEO and other NEOs, despite positive TSR was largely a result of smaller restricted stock awards made in 2021 relative to 2020 although following Mr. Boyle’s hiring in December 2020, he was awarded a restricted stock grant of similar size in March 2021 as the other NEOs received in August 2020. The decline in CAP in 2022 to both the CEO and other NEOs was primarily a result of the decline in the value of the Company’s common stock as reflected in the TSR. As noted above, the Company’s TSR in 2022 underperformed the Peer Group, but in general, valuations of the common stock of publicly traded Banks declined in 2022. The decline in the valuations of bank stocks in 2022 reflected the uncertain economic environment characterized by the general increase in interest rates and the inversion of the yield curve. |  |  |  |
