Plan care for aging parents and divide responsibilities more fairly.

Take careful steps toward contact after a falling-out or estrangement.
For many people, a sibling is the person who has known them the longest. That shared history can bring deep loyalty and understanding. It can also carry old rivalries, unspoken resentments, and family roles that never quite went away. When parents age, a family crisis hits, or a disagreement turns into silence, those old patterns often come back with force.
This guide explains what sibling therapy is, what it can help with, how sessions work, and what to expect from online sibling therapy in California with Heartfelt Flourish.
Sibling therapy, also called adult sibling therapy or sibling relationship therapy, is a form of relationship therapy for brothers and sisters who want to work on their connection. A therapist meets with two or more siblings, helps each person feel heard, and guides them through the patterns and hurts that have strained the relationship. At Heartfelt Flourish, sessions take place online and last 50 minutes.
The goal is to understand what has been happening between you, repair what can be repaired, and build a relationship between adults, rather than one shaped by who you were as children. For some siblings, that means growing closer. For others, it means finding a respectful way to cooperate, especially when family decisions need to be made together.
Sibling therapy can help adult brothers and sisters who:
If your sibling is not ready to join, you can begin on your own. Individual therapy can help you understand your part in the relationship, work through the hurt, and decide what you want.
Sibling relationships are often the longest relationships in a person’s life, lasting beyond relationships with parents and often beginning before relationships with partners or friends. Siblings share a family history that no one else fully understands, which can make the bond a source of support, and also a place where old wounds stay raw.
Childhood roles tend to follow siblings into adulthood: the responsible one, the peacemaker, the one who always gets blamed, the one who left. When these roles no longer fit, they can create friction that neither sibling knows how to change on their own.
Feelings about who was praised, protected, or blamed growing up often linger for decades. A comment at a family dinner can reopen an old wound in seconds. Therapy gives siblings a structured way to talk about these memories, understand each other’s experience, and stop reliving the same competition.
Many adults find that a single phone call with a sibling can pull them back into the role they played as children. Therapy helps you notice these roles and relate to each other as the adults you are now.
When parents grow older or become ill, siblings often have to make decisions together about care, living arrangements, and money. Old tensions frequently resurface, especially when one sibling carries more of the load. Therapy helps siblings divide responsibilities more fairly and make decisions with less conflict. When parents also need to be part of the conversation, family therapy with adult children may be a better fit.
Disagreements about inheritance, family property, or financial help can feel like they are about money, while often being about fairness, recognition, and old hurts. Therapy helps siblings separate the practical questions from the emotional ones, so both can be addressed. Our therapists provide emotional and relational support and do not give legal or financial advice.
When siblings marry and start families, loyalties shift. A sibling’s partner may clash with the rest of the family, or holidays and traditions may become a source of tension. Therapy creates space to talk about these changes openly.
Some siblings drift apart slowly. Others stop speaking after a painful conflict. Therapy can help you understand what happened and, when both people are willing, take careful steps toward contact at a pace that feels safe.
Our therapists are trained as Marriage and Family Therapists and use Emotionally Focused Therapy (EFT), one of the most researched approaches to relationship therapy. EFT looks at the emotions and needs beneath each person’s reactions, and at the cycle that forms between people.
Between siblings, that cycle might look like this: one sibling feels unappreciated and responds with criticism, while the other feels judged and withdraws. Each response makes the other stronger, often in the same way it did when they were young. Therapy helps you see this cycle, talk about the feelings underneath it, and respond to each other in ways that rebuild trust.
In the first session, your therapist meets with the siblings taking part to understand your family history, what has been happening recently, and what each of you hopes will change. Each person gets space to share their view without being interrupted or blamed.
In the sessions that follow, you work on the specific patterns that cause distance or conflict, practice new ways of raising concerns and listening, and work through hurts that need repair. Your therapist stays neutral and helps keep conversations respectful, even when topics are difficult.
Online sibling therapy in California at Heartfelt Flourish usually follows a similar path:
All sessions take place through a secure video connection and last 50 minutes. Siblings can join from separate locations, which makes regular sessions possible even when you live in different cities.
Because our therapists are licensed in California, every sibling taking part needs to be physically located in California during sessions. A sibling who lives in another state cannot join from there. We work with clients in Los Angeles, San Diego, San Jose, San Francisco, Sacramento, Fresno, Oakland, Irvine, and communities throughout the state.
The length depends on what you are working on. Siblings facing one specific decision, such as planning care for a parent, may need only a few sessions. Decades of resentment or a long estrangement usually take longer. Your therapist reviews progress with you along the way, so you always know where things stand.
If you are unsure which fits, your therapist can help you decide during your consultation. You can also read more about family therapy for families at every stage.
Sibling therapy may help if:
Joint sessions work best when every sibling feels safe enough to speak openly. If there is a history of abuse between siblings, threats, or one sibling feels afraid of another, joint sessions are not the right place to start. In that case, we will talk with you about safer options, such as individual therapy, before any joint work begins.
Heartfelt Flourish is an online-only practice that offers online sibling therapy in California to adults across the state. Our team includes Licensed Marriage and Family Therapists (LMFT) and Associate Marriage and Family Therapists (AMFT). Associates provide therapy under the clinical supervision of a licensed clinician, as California law requires.
We see the relationship as the client. That means we don’t take sides, and we make sure each sibling feels heard from the very first session.
Reaching out about a sibling relationship can feel uncomfortable, especially when the history is long. It can also be the step that changes how your family works for years to come. Book a consultation, and we’ll talk about what’s happening and how we can help.

Sibling therapy is relationship therapy for adult brothers and sisters who want to work on their connection. A therapist helps each sibling feel heard, understand the patterns and roles that have strained the relationship, repair hurt, and build a healthier relationship as adults.
Sibling therapy works best when the siblings involved in the conflict take part. Not every sibling has to join. If your sibling isn’t ready, you can start on your own with individual therapy and decide later whether joint sessions make sense.
Sibling therapy can help with old rivalries and favoritism, family roles that no longer fit, disagreements about caring for aging parents, conflict over money or inheritance, tension involving partners and in-laws, and distance or estrangement.
Yes. Therapy gives siblings a structured place to plan care, divide responsibilities more fairly, and work through old tensions that often resurface during caregiving. If parents need to be part of the conversation, family therapy with adult children may be a better fit.
No. Our therapists are licensed in California, so every sibling taking part needs to be physically located in California during sessions. Siblings in different California cities can each join online from their own location.
Sibling therapy focuses on the relationship between brothers and sisters. Family therapy usually includes parents and other family members and looks at how the whole family system affects each relationship.
You can still begin on your own. Individual therapy can help you understand the relationship, work through your own hurt, and think about how to invite your sibling later without adding pressure.
Each session lasts 50 minutes. Siblings working on one specific decision may need only a few sessions, while long-standing resentment or estrangement usually takes longer. Your therapist reviews progress with you along the way.
We don’t bill insurance companies directly. If your plan includes out-of-network mental health benefits, you may be able to request reimbursement. Check with your insurance provider about your coverage, and ask us about it during your consultation.
