Graduate school and thereafter is a stressful time in your life. Juggling home, work, school, papers and finally practicum experiences can cause an upheaval in your relationships. This group is to help with pent up emotions and a guidance for anxiety reduction. As a therapist it is extremely helpful to get your own therapy, and experience what your clients feel when they are in the room.

FAQs - About Group Therapy and Support Groups

How can I find a support group in San Dimas?

To find a support group in your area, start by entering your city, zip code, or the name of the group into the search bar at the top of the page. When searching, consider whether you prefer an in-person or virtual group. This can help you decide how broad your geographic search should be. If you are open to virtual groups, you might want to search by state instead of just your city, especially if there are limited options nearby.

Once you complete your search, you can use the filters to narrow the results by selecting specialties (such as grief, trauma, or eating disorders), therapeutic approaches, age groups, and other criteria to find a group that best fits your needs.

How does group therapy work?

Group therapy is led by one or more trained therapists and provides a space where participants can process their experiences and learn from others facing similar challenges. Groups may focus on a specific issue—such as addiction, grief, physical illnesses, parenting, or caregiving—or they may center around a particular therapeutic approach, such as Cognitive Behavioral Therapy (CBT), social skill development, or Exposure Therapy. Some groups are also designed for specific populations, such as teens, veterans, or LGBTQ+ individuals.

It’s also important to distinguish group therapy from peer-led support groups, like Alcoholics Anonymous. While both can offer valuable support, therapy groups are typically led by licensed professionals and follow a more structured format. Therapy groups often meet for a fixed length of time with a consistent group of members, while many peer support groups meet for an indefinite period of time with members coming and going.

What are the benefits of group therapy?

Group therapy offers several important benefits. It brings together people facing similar challenges—whether related to mental health, physical health, or life transitions—and creates a supportive environment where participants can exchange feedback, share experiences, and learn from one another. Hearing different perspectives can help individuals discover new coping strategies and practical tools they may not have encountered on their own. Sharing personal experiences, such as coping with a serious illness or navigating family struggles, can also reduce feelings of isolation and foster a sense of connection and understanding. In addition to emotional support, group members often gain useful, real-world advice from peers who have faced similar situations.

Group therapy is typically more affordable than individual therapy and, for certain conditions, can be equally effective. Many groups also include structured activities—such as guided journaling, cognitive-behavioral exercises, or role-playing—to help participants develop concrete skills they can apply in daily life.

Is group therapy as effective as individual therapy?

It is difficult to make a blanket statement about the effectiveness of support groups, as they vary widely in focus and the conditions they address. However, support groups can be highly valuable in helping individuals gain emotional support and achieve meaningful treatment outcomes. For certain conditions, such as substance use, research has shown that group therapy can be particularly effective—sometimes just as effective as individual therapy—in supporting long-term recovery.

Many professionals attribute the effectiveness of group therapy to the unique benefits of the group setting, which fosters peer-to-peer learning and a sense of connection through shared experiences. Group settings also offer accountability and encouragement from both facilitators and fellow participants, which helps sustain motivation and supports continued progress. These factors together play a key role in promoting the overall effectiveness of group therapy.

How much does group therapy cost?

Group therapy is typically less expensive than individual therapy, with sessions typically costing between $50 and $75 each. In comparison, individual therapy can cost anywhere from $100 to $200 or more per session, even with insurance. Some therapists or organizations offer low-cost or free group therapy options, particularly through community centers or nonprofit organizations. In some cases, groups may require payment upfront for a set number of sessions, such as paying for six weekly sessions at the first meeting. However, many providers offer payment plans to help make participation more accessible if this upfront payment is required.

Does insurance cover group therapy?

As with individual therapy, insurance coverage for group therapy varies based on factors such as your specific insurance plan, the purpose of the group, your diagnosis, and whether the group provider is in-network. Many insurance plans cover group therapy sessions that address diagnosable mental health conditions, such as substance use disorders, anxiety, or depression.

However, groups that focus on topics not directly tied to a mental health diagnosis—such as parenting support or divorce recovery—are less likely to be covered. Because coverage can vary widely, it’s important to check with your insurance provider before joining a group to confirm whether the sessions will be covered and what out-of-pocket costs you may be responsible for.

How long does group therapy last?

The length of each group therapy session typically ranges from 45 minutes to two hours, depending on the therapy approach, the group’s goals, and how often the group meets. In some cases, group therapy is part of a larger treatment program, such as an Intensive Outpatient Program (IOP), where group sessions complement individual therapy and are scheduled as part of the program’s overall structure.

The duration of participation in a group also varies. Some groups are designed to be short-term, lasting anywhere from 6 to 24 weeks—for example, bereavement groups or skills-based groups like those using Dialectical Behavioral Therapy (DBT). Other groups may be longer-term, lasting a year or more, and some ongoing support groups meet indefinitely, allowing participants to stay as long as they find the group helpful.

What are the limitations of support groups?

Support groups offer many benefits, but they also have certain limitations. Unlike therapy groups, many support groups do not provide formal therapeutic treatment and are not led by licensed mental health professionals. For individuals seeking clinical treatment for specific mental health diagnoses—such as depression, eating disorders, or substance use—individual therapy or group therapy led by a licensed professional may offer more personalized and specialized care.

The effectiveness of a support group also depends heavily on the group’s participants and the overall group dynamic. When members engage respectfully and offer constructive support, the group can foster valuable peer-to-peer learning. However, if certain participants dominate discussions, provide inaccurate advice, or create conflict, it can disrupt the group’s sense of safety and reduce its effectiveness. Confidentiality can also be harder to maintain in support groups, particularly in open groups where participants can join or leave at any time. With new members regularly entering the group, it can be more difficult to build and sustain a consistent sense of trust and privacy.
