History and Facility Update

The North St. John’s Swim and Tennis Club was established in 1964 at the end of Marydell Road in Ellicott City, Maryland. The eight acres of land was a gift by surrounding neighbors to start a local swim club.  NSJ celebrated its 50th Anniversary in 2014 and has continued to maintain the original appeal. We are honored to have some founding members and their younger generations as part of the NSJ family.

NSJ is run by volunteers that consist of the Board of Directors.  There are five Executive Board positions and eight Directors.  In 2011 we hired Continental Pools Inc., a pool management company, to oversee the facility maintenance, staffing and training of employees.  In Fall 2017 we changed pool management companies and will now be maintained and staffed by American Pool, Inc..

The club is a high-usage facility during the months of May through September. To retain membership and a wait list, we need to constantly maintain the pool, club house, tennis courts and grounds. We have consistent membership retention and primarily draw from the immediate Ellicott City area which includes 5 elementary schools (Hollifield, St. John’s Lane, Waverly, West Friendship and Manor Woods), 2 middle schools (Patapsco and Mount View), 2 high schools (Mt. Hebron and Marriott’s Ridge) and 2 private schools (Resurrection and St. John’s Parish Day School). 

Over the last eight years we have continued our initiative to build and retain a wait list.  We’ve partnered with Howard County to promote our club through the Recreation & Parks website; we’ve advertised through Howard Magazine to elevate our presence in the community and increase our visibility to those families moving to Howard County; and we continue to partner with our supporting schools through their fundraising efforts.

Over the last decade the pool and surrounding grounds have been maintained and upgraded as funding permits.  We first renovated the club house to include a full-service snack bar, ADA accessible restrooms, an office and front desk/check-in area.  Following the club house renovation, the pool and surrounding deck area were updated for the 2011 season.  Most of the renovations have been done in phases because a loan was necessary to fund the expenditures.


NSJ continues to maintain a five-year plan for necessary projects to improve our facility as well as utilize all available resources. We have applied once again for the Private Community Pool Grants for FY 19 (July 1, 2018 through June 30, 2019).

Grant Money Received

2013: The Grant money received from 2013 was instrumental in making NSJ ADA compliant.  We updated our Lifeguard Equipment and added an ADA Lift.  We were also able to purchase additional safety items that otherwise would not have been added. 

2014: The Grant money from 2014 was used to purchase pool covers for both the main and wading pools. 

2015: The Grant money from 2015 helped defer the costs of purchasing two new diving boards. 

2016: The Grant money from 2016 was used to upgrade the main pool and wading pool plumbing. 

2017: The Grant money from 2017 was used to paint the clubhouse and replace the roof on the shed and grilling gazebo.

Over the last eight months we’ve been busy behind the scenes.  In the fall we had white coats applied to both the main and wading pools.  During the process we uncovered some leaks in the skimmers and main drain of the main pool. When it rains, it pours, and we found additional leaks in the main pool.  The unexpected plumbing repairs to the main pool were addressed along with the leaks in both the main pool and wading pool pump rooms. We cleaned out the DE pit located in the lower area.  Our hope is that the pool is no longer leaking and the lower area is significantly drier this summer.


Credit Cards

NSJ accepts credit cards at the front desk and the snack bar. Members have the option of paying for guest fees, parties and events with check or credit.


Blue Marlin Grill

The Blue Marlin Grill will be operated by Ralph Santucci, owner of Vocelli’s, and managed by Zeeshan Uddin.  Information will be sent out before the pool opens so you can plan your meals accordingly.  Vocelli’s has been a strong supporter of NSJ and our events; they donate back to NSJ a percentage earned during the summer.
