Sam Dogen, a San Francisco father of two, says park rangers questioned him while he practiced tennis with his children at Golden Gate Heights Park. The encounter occurred after Dogen returned from a family trip to Hawaii and brought his 6-year-old daughter and 9-year-old son to an apparently available public court. Rangers asked whether he had a permit to teach tennis. No citation was issued, but Dogen said he was warned that unauthorized instruction could result in a $192 fine.
The interaction has prompted debate over how public park rules should distinguish between commercial coaching and parents teaching their own children. City officials said rangers routinely check whether instruction on public courts is paid or commercial. Dogen said he understands the need to regulate businesses but believes family activities should be handled differently.

Family tennis session draws ranger questions
The encounter took place at Golden Gate Heights Park after Dogen returned with his children from Hawaii. He said he brought them outdoors to help them adjust to the time difference and practice tennis. About 20 minutes into the session, two park rangers approached the family.
According to Dogen, the rangers asked whether he had a permit to teach tennis. He said the question surprised him because the players were his own children and he was not conducting a public or paid class. He also said no one was waiting to use the court.
I took the kids out for what I thought would be a nice afternoon, to get over the jet lag, be outside in the sun and go play some tennis like we have done many, many times.
Warning issued without a citation
Dogen said the discussion ended after his 9-year-old son identified him as his father. The family was not cited, and Dogen described the outcome as an educational warning. However, he said one ranger told him that teaching tennis without the required permit could lead to a $192 penalty.
The father said he focused on keeping the situation calm while his children stood nearby. He questioned why the family had been interrupted while using an available public court for a private activity.
City explains public-court enforcement
The parks department said rangers routinely determine whether people providing instruction on public courts are operating commercially. Paid tennis instruction is not permitted on public courts without a permit, so questions about the nature of an activity are part of routine enforcement.
Officials said rangers ask questions to distinguish commercial instruction from personal recreation or parents coaching their children. The interaction was characterized as routine. The department did not indicate that Dogen had been cited or that the family had violated a rule.
Father says the encounter unsettled his children
Dogen said he understands why San Francisco regulates professional tennis instruction on public courts. His objection is that similar scrutiny can appear to apply when a parent is helping children learn a sport. He said the encounter was difficult because it occurred in front of young children during a relaxed family outing.
He also connected the incident to the broader pressures of raising children in San Francisco. His immediate response, he said, was to de-escalate the situation and protect his children from becoming more distressed.
Incident fuels calls for family-friendly rules
Dogen said he may carry his children’s birth certificates in his tennis bag during future park visits, a joke intended to show how unusual the encounter felt. He said he would not seek a permit to teach his own children because he views the activity as family recreation rather than commercial instruction.
The episode raises a practical question for public-park enforcement: how can rangers identify paid coaching without unnecessarily disrupting parents and children? Dogen said he hopes officials will adopt a more family-friendly approach while continuing to address commercial use of public courts.

Summary
A routine check for unauthorized commercial instruction became a surprising encounter for a San Francisco father practicing tennis with his children. Although no citation was issued, the warning about a possible $192 fine led Dogen to question whether enforcement distinguishes paid coaching from family recreation. The parks department said its rangers were following a routine process designed to identify commercial use of public courts.
