Teen Life Coach in Greenbrae, California

You have given your teenager every advantage, and you are still watching them quietly come apart. They are bright. They are capable. Their teachers say good things. And yet something is missing — a sense of who they are, where they fit, what they actually want — and you cannot seem to find the adult who can reach them. If your family lives in Greenbrae, there is a reason the usual answers have not worked: your teen’s school is in one town, their sports are in another, their friends scatter across multiple ZIP codes, and every specialist you have tried is always somewhere else. You want your teen not just to be ready for the next level of school — but the next stage of life. You are in the right place.

Jeffrey Leiken, MA, provides teen life coaching for Greenbrae families — including those navigating the Kentfield School District pipeline and the high school decision fork that defines adolescence in this community. He is not a therapist and does not position himself as one. He is a life coach and mentor: someone whose depth of knowledge and skills gives teens the tools to navigate a complex, high-achieving world with confidence and clarity. Evolution Mentoring™ is not academic tutoring, executive function coaching, or clinical psychotherapy. It is a sustained coaching and mentoring relationship built on honesty, skill-building, and real results.

Jeff holds a Master’s degree in Educational Counseling and has completed more than 50,000 hours of one-on-one work with teenagers and young adults over three decades. Though he works with adolescents globally, his local office is in Mill Valley — approximately ten minutes from Greenbrae — and his depth of experience across the entire Central Marin school network means he already understands whichever community your teen is entering. He also works with families in neighboring Kentfield, Larkspur, and Ross — all within fifteen minutes of Greenbrae.

Jeff works with families throughout Greenbrae and the surrounding communities that share the 94904 ZIP code. Note that 94904 is shared with Kentfield — the two communities are served by the same Kentfield School District and overlap significantly in school and social networks:

• Bon Air / Bon Air Hill — 94904 (Sir Francis Drake Blvd corridor; Bacich / Kent MS district)
• Spyglass Hill — 94904 (hillside condos above Sir Francis Drake; Bacich / Kent MS district)
• Via Casitas / Upper Via Casitas — 94904 (central residential; Bacich / Kent MS district)
• South Eliseo Drive area — 94904 (established single-family homes; Bacich / Kent MS district)
• Greenbrae Boardwalk — 94904 (waterfront residences along Corte Madera Creek)
• Almenar Drive / North Greenbrae hillside — 94904 (hillside homes with bay views; Bacich / Kent MS district)
• Corte Oriental / Corte Cayuga — 94904 (quiet cul-de-sac family streets; Bacich / Kent MS district)

He also works with families in neighboring Kentfield (94904), Larkspur (94939), and Ross (94957) — communities that share school systems and social networks with Greenbrae families.

Greenbrae does not have a downtown. It does not have a middle school. It does not have a high school. What it has is approximately 7,700 residents, a median household income above $269,000, a waterfront path along Corte Madera Creek, the Bon Air Center as its closest approximation of a community hub, and Sir Francis Drake Boulevard running through the middle of it toward MarinHealth Medical Center. It is a residential enclave positioned between Larkspur, Kentfield, and San Rafael — a place where families live and send their children — and it asks more of its teenagers than most communities its size.

What makes teen mentoring in Greenbrae distinct is this: every major developmental threshold a teenager crosses here happens — physically and socially — in another town. Elementary school at Bacich is in Kentfield. Middle school at Kent is in Kentfield. High school is in Larkspur, Ross, San Rafael, or wherever the family decides. The social world that a Greenbrae teen inhabits is always borrowed from a neighboring community. As kids move into their teen years, that dynamic intensifies at precisely the moment when adolescent identity is being formed.

A 2024 youth-led survey through the Marin County AIM Ideas Lab found that nearly 90% of local teens report anxiety among their peers, more than 86% report high stress or burnout, and over 70% report depression or low self-esteem. For Greenbrae teens, those numbers do not exist in isolation. They exist inside a community structure that never fully anchors its young people to a single place. Teen coaching in Marin County addresses that need directly, and Jeff has worked with families navigating exactly this dynamic for more than two decades.

The families Jeff works with in Greenbrae are not struggling because of a lack of resources. They are struggling because their teenager moves through multiple community identities without being fully claimed by any of them — and because the question of who I am is impossible to answer when where I belong changes every two years. Youth mentoring in Greenbrae, CA, addresses that question directly, before it compounds into something harder to resolve.

You have invested in your child’s education deliberately, choosing high-performing Central Marin schools including Bacich Elementary and Kent Middle School in Kentfield. Jeff has worked with families navigating this exact landscape for more than two decades. His understanding of each school’s internal culture — the social dynamics, the transition points where confidence erodes — comes from sustained, direct experience with students and families across all of these communities.

The four most common high school destinations for Greenbrae teens are Redwood High School in Larkspur (approximately 1,785 students, ranked #399 nationally and #50 in California), Marin Catholic in Kentfield (approximately 725 students, faith-based), The Branson School in nearby Ross (approximately 420 students, college-preparatory), and Marin Academy in San Rafael. Kent Middle School (800 College Avenue, Kentfield, CA 94904, approximately 522 students) is where Greenbrae teens spend their middle school years before dispersing across these four very different school communities. Jeff helps teens and families navigate that transition before the challenges become crises, and helps parents make the high school decision based on their teenager’s actual personality and needs — not rankings or peer pressure.

Jeff does not provide academic tutoring, executive function coaching, or ADHD support for any of these school communities or anyone else. What he provides is a sustained mentoring relationship focused on identity formation, personal direction, and the confidence that carries a teenager through whichever high school they enter — and whoever they find themselves becoming inside it.

Greenbrae families navigate a uniquely fragmented landscape. Their teenager’s school, social life, and support resources are located in neighboring towns. The search for consistent teen support in this community is itself an exercise in going elsewhere. Mentor Counseling® provides what the community’s geography cannot: a single trusted relationship that follows the teenager across whichever school system they are part of and remains constant through every community transition they navigate.

Teen life coaching through Evolution Mentoring begins with a minimum six-month commitment — long enough to build genuine trust and create lasting change. Sessions are virtual, giving Greenbrae families flexibility and privacy without requiring another trip to another town. Jeff’s model includes 24/7 access: when a Greenbrae teen at Redwood HS is navigating a social crisis, or when a Greenbrae family is agonizing over the Marin Catholic vs. Branson decision at 11 p.m., Jeff is available directly by text or phone. Because he is based in Mill Valley and has worked across the entire Central Marin network for 25+ years, his knowledge of each school community is not secondhand.

Jeff’s programs address the specific pressures Greenbrae teens face at each transition point. For teen boys entering the competitive social environment of a new high school — Redwood, Branson, or Marin Catholic — Boys To Mensch® provides the identity framework for navigating a peer culture they did not grow up inside. HeroPath® guides older teens through the life-direction questions that accumulate when a teenager has passed through multiple community identities without a clear sense of which one is theirs. Adolescent coaching for Greenbrae teens includes personal growth coaching, focus and motivation work, emotional regulation, and confidence-building for young people who are capable but unmoored.

Jeff also provides parent coaching for Greenbrae families — particularly during the high school decision period, when parents and teenagers often disagree about the right choice. Explore Jeff’s teen coaching approach in detail. Online teen life coaching and virtual teen coaching are available for all Greenbrae families.

More than two-thirds of the families Jeff works with across Marin County came to him after conventional approaches did not produce the change they hoped for. For Greenbrae families — where teen support infrastructure is located in neighboring Kentfield and Larkspur — having a mentor who already knows the entire Central Marin ecosystem eliminates the fragmentation problem rather than adding to it.

Greenbrae’s teen support resources — therapists, academic coaches, ADHD specialists — are located primarily in neighboring Kentfield and Larkspur. Families seeking help for their teenager are already accustomed to going elsewhere. What they describe finding there is a fragmented landscape of specialists, each addressing one dimension of a teenager’s struggle, with no single relationship holding the whole picture. Teen mentoring in Greenbrae, CA, is built around a different premise: one consistent mentor who knows the teenager, the family, and the community across multiple years.

When a teen’s struggles are clinical — when they need diagnosis, treatment, or medication management — Jeff refers families to qualified therapists and psychologists. He does not diagnose. He does not treat pathology. His work begins where clinical need ends. Two-thirds of Jeff’s clients across Marin County come to him after conventional therapy did not achieve the results the family hoped for. These are not families who rejected clinical support — they tried it, and found that their teenager needed something different: a sustained relationship focused on development rather than treatment.

Teen mentoring vs. therapy in Greenbrae is not a binary choice. For the teenager who is clinically fine but directionless — bright but stuck, capable but struggling to articulate what they want or who they are becoming — mentoring provides what therapy structurally cannot: a guide, not a clinician. An alternative to teen therapy for struggling teens in Greenbrae is not a compromise. For the right teenager, it is the more appropriate path.

Jeff does not replace academic specialists. When ADHD assessment, executive function coaching, or learning disability support is needed, he complements those services — he does not compete with them.

Jeff is based in Mill Valley, California — approximately ten minutes from Greenbrae — and has served Marin County families from within this community for more than 25 years. He holds a Master’s degree in Educational Counseling. He holds a Pupil Personnel Services (PPS) Credential from the State of California. He served as Adjunct Faculty at the University of San Francisco. He has guest lectured at Stanford University. He is a Master Practitioner of Neuro-Linguistic Programming and co-creator of the HeroPath® program.

Jeff has presented at more than 200 professional conferences across 17 countries and 4 continents. He has trained more than 60,000 parents, teens, and professionals. He has delivered a TED talk on adolescent development. He is the author of Adolescence Is Not A Disease. He has completed more than 50,000 hours of one-on-one mentoring with teenagers and young adults.

For Greenbrae families who are navigating a fragmented landscape of specialists and neighboring-town resources, Jeff’s depth of experience across the entire Central Marin school network — Bacich, Kent MS, Redwood HS, Marin Catholic, Branson, Marin Academy — means he is not a provider who needs to be briefed on the community. He already knows it. Learn more about Jeffrey Leiken’s background.
