Teen Life Coach in Kentfield, California

Your teenager is doing everything right. They show up for practice. They make their grades. They carry the weight of your family’s values with a seriousness that once made you proud — and now quietly worries you. Somewhere between the varsity roster, the honors courseload, and the Sunday expectations, the person inside the performance has started to disappear. You cannot name exactly what is wrong, because nothing is technically wrong. But a parent knows the difference between a teen who is thriving and a teen who is holding it together, and you are watching the second one. You want your teen not just to be ready for the next level of education  — but the next stage of life.

Jeffrey Leiken, MA, provides teen life coaching for Kentfield families — including those whose teens attend Marin Catholic High School and Adaline E. Kent Middle School. 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 the collision of faith, academics, and athletics 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 Kentfield — and he has served Marin County families in this community for more than 25 years. He is not another appointment on an already-full calendar, and he is not another system asking your teen to perform. He is the guide who helps bright, pressured kids find the person underneath the performance — and helps families like yours stop waiting for the collapse they quietly fear.

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

• Kent Woodlands — 94904 (hillside estates toward Mt. Tamalpais; Bacich / Kent MS district)
• College of Marin area / College Avenue — 94904 (central Kentfield; Bacich / Kent MS district)
• Greenbrae border / Bon Air — 94904 (Sir Francis Drake corridor; Bacich / Kent MS district; shared with Greenbrae)
• Sir Francis Drake corridor — 94904 (main commercial and residential spine of Kentfield)
• McAllister / Fay Drive area — 94904 (established single-family residential; Bacich / Kent MS district)
• Tamalpais Road / Upper Kentfield hillside — 94904 (larger hillside homes; Bacich / Kent MS district)

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

Kentfield is a community of approximately 6,800 residents that occupies a distinctive position in Marin County’s geography and culture. The College of Marin’s main campus anchors one end of town. The hillside estates of Kent Woodlands rise toward Mount Tamalpais at the other. Hal Brown Park at Creekside provides a gathering point between them. This is a community where median home values exceed $3 million, where the resources available to families are extraordinary, and where two very different school cultures coexist within the same few square miles.

That dual identity is what makes growing up here distinct from every other community in Marin County. Marin Catholic High School, a private Roman Catholic institution, serves families whose values are shaped by faith alongside academic ambition. Kent Middle School, part of the Kentfield School District, serves public school families whose teens will soon face the most consequential choice of their adolescence: Redwood High School in Larkspur, Marin Catholic, The Branson School in nearby Ross, or Marin Academy. In a community this connected, every family knows which path every other family chose — and that visibility turns a school decision into an identity statement.

The median household income in Kentfield exceeds $200,000 (U.S. Census Bureau). 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. As kids move into their teen years, the particular pressure of this community — where faith, academics, athletics, and social expectation collide — continues to intensify. Jeff has worked as a teen coach and youth life coach here for more than 25 years, and the patterns he sees are shaped by that collision.

You have invested in your child’s education deliberately, choosing high-performing Kentfield schools including Adaline E. Kent Middle School and Marin Catholic High School. Jeff has worked with families in these specific school communities for more than two decades. His understanding of each school’s internal culture — the social hierarchies, the identity pressures, the moments where teens most often lose their footing — comes from sustained, direct experience with students and families across both institutions.

Marin Catholic High School (675 Sir Francis Drake Boulevard, Kentfield) is a private, Roman Catholic, co-educational college-preparatory school enrolling approximately 750 students in grades 9 through 12, offering honors and AP coursework alongside 28 competitive sports teams (Niche, Marin Catholic). The student Jeff works with most often at Marin Catholic is not failing in any one area. They are performing across academics, athletics, and faith-community expectations simultaneously — while quietly carrying an identity tension that none of those systems is designed to address.

Kent Middle School (800 College Avenue, Kentfield, CA 94904) is a California Distinguished School and Gold Ribbon School enrolling approximately 522 students in grades 5 through 8, fed by Bacich Elementary (K–4). After eighth grade, Kent MS students face the fork that defines this community: Redwood High School in Larkspur (public), Marin Catholic (faith-based private), The Branson School in Ross (secular elite), or Marin Academy in San Rafael. This decision — and the pressure surrounding it — is one of the most common intervention points for families who contact Jeff. The choice is never just about academics. In a community where every family’s school decision is known, it becomes a statement about values, identity, and aspiration.

Jeff does not provide academic tutoring, executive function coaching, or ADHD support for Marin Catholic students or anyone else. What he provides is a sustained mentoring relationship focused on identity, confidence, and character development — the questions that sit at the intersection of faith, achievement, and selfhood.

When families here search for help with their teenager, they find academic tutors and executive function coaches. Jeff is neither. Mentor Counseling® addresses what those services cannot — the identity crisis that sits underneath the academic struggles, the social withdrawal, or the quiet loss of motivation. A Marin Catholic student earning straight A’s and starting on the varsity team but privately falling apart does not need a tutor. They need someone who can help them understand who they are becoming — and Jeff’s non-diagnostic, values-respecting approach is often what makes the difference for families in this community.

Teen life coaching through Evolution Mentoring begins with a commitment of three to six months — long enough to build the kind of trust that weekly tutoring sessions or occasional school counselor check-ins cannot create. Jeff’s model includes 24/7 access: when a Kent MS student has a social crisis at nine o’clock on a school night, or a Marin Catholic athlete is spiraling before a critical game, they can reach Jeff directly by text or phone. Life coaching in Kentfield is not an appointment. It is a sustained relationship with someone who understands the specific pressures your teen carries.

Within that relationship, Jeff draws on specific programs. For teen boys navigating Marin Catholic’s 28 competitive sports programs — where athletic identity, academic pressure, and faith-community expectations stack on top of each other — Boys To Mensch® addresses the layered identity confusion that this collision creates. For teen girls navigating the social dynamics of a faith-based community where expectations around behavior, relationships, and self-presentation carry additional moral weight, Clean Communication for Teen Girls™ provides frameworks for honest, self-respecting relationships. For juniors and seniors, HeroPath® offers structured guidance through college readiness and the deeper question it forces.

Jeff also provides private, one-on-one adolescent coaching focused on personal growth, emotional regulation, motivation, and deep self-knowledge. Explore Jeff’s teen coaching approach in detail. All sessions are virtual, giving families convenience and privacy. Jeff is based in Mill Valley, approximately ten minutes away. He also works with young adults from Kentfield navigating the college transition, and offers parent coaching for families working through the particular pressures of raising a teenager where faith, academics, and athletics collide.

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 faith-based families especially, Jeff’s non-clinical approach often resonates where secular models did not.

The decision between mentoring and therapy is not a competition — it is a question of fit. When a teenager’s struggles are clinical — when they need diagnosis, medication management, or therapeutic treatment — Jeff refers families to qualified therapists and psychologists. He does not diagnose. He does not treat pathology. His work begins where clinical need ends.

For the families Jeff works with here, the reality is that their teenager is not mentally ill. They are stuck. Bright but overwhelmed by the convergence of academic, athletic, social, and — for Marin Catholic families — faith-based expectations. Healthy enough that a clinical diagnosis does not fit, but struggling enough that doing nothing is no longer an option. An alternative to teen therapy in Kentfield that focuses on development rather than treatment, on character rather than compliance, is what these families are seeking.

Two-thirds of Jeff’s clients come to him after therapy did not achieve the results the family hoped for. For faith-based families in particular, Jeff’s non-diagnostic approach — working with the whole teen, including their values and beliefs, without pathologizing — often resonates where secular clinical models did not.

Jeff does not replace academic specialists either. When ADHD assessment, executive function coaching, or learning disability support is needed, he complements those services. Many families here use Jeff alongside the academic tutors and EF coaches that appear in local search results — because mentoring addresses the person underneath the performance, not the performance itself.

Jeff holds a Master’s degree in Educational Counseling — a credential that carries particular weight for faith-based families seeking qualified, professional guidance for their teenager that respects their values without imposing a clinical framework. He holds a Pupil Personnel Services 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 has presented at more than 200 professional conferences across 4 continents and 17 countries, including a TED talk on adolescent development. He has trained more than 60,000 parents, teens, and professionals. He is the author of “Adolescence Is Not A Disease.” He is a Master Practitioner of Neuro-Linguistic Programming and co-creator of the HeroPath® program.

Jeff is based in Mill Valley, approximately ten minutes from Kentfield, and has served families across Marin County for more than 25 years. For families here — whether connected to Marin Catholic’s faith-based community or the Kentfield School District’s public pipeline — Jeff’s credentials represent decades of direct work with the kinds of teenagers this community raises: bright, pressured, and navigating the collision of achievement, identity, and values.
