I enjoy working with people who are struggling with substance use, whether they are just beginning to question their use and habits or they have experienced chronic relapse and feel hopeless. I believe part of that process is ensuring they are informed of options available and helping them discover their “why.” I have experience supporting people in identifying their strengths, finding coping skills, and creating measurable, attainable goals. I am skilled at navigating treatment systems/levels of care in Massachusetts. I have experience with medical detoxification protocols and can discuss options for medication-supported treatment.

I'm a Psychotherapist in Private Practice for 40+ years, with an enduring capacity to blend psychological/spiritual principles and practices, women's health rights & power, and often help cultivate the willingness to break through thought/behavior patterns to experience real change. We often live our lives as though we're trying to measure up to other's expectations, failing to make choices that are our own. My passion is to help people to break that spell, choosing for themselves how to live the life they are meant to live, not the lives others want them to live. This is a serious intentional and joint process to join.

When was the last time that you felt truly listened to, heard & understood? You more than likely talk to many people throughout your day but how often are you making connections with others that feel truly authentic? Many people are currently feeling isolated even when surrounded by others because they do not have someone in their life creating a welcoming and safe space that allows them to feel comfortable enough to share their worries & struggles. Therapy can be this place, where building a trusting relationship with a compassionate practitioner can allow you to feel seen & can support improvements in your health & well-being.

I am accepting, interactive, and easygoing. I believe in focusing on the current situation in peoples' lives, and explore the past as long as it has a demonstrable benefit for a client's present day functioning. I believe it is important to customize my approach to a client's style, situation, and needs. As much as possible, I draw on a person's emotional and physical "intelligence" to complement his or her cognitive understanding. It is essential that my clients feel in charge of their direction and pacing, and safe enough to take the necessary risks.

Is everyone in the Psychology Today Therapy Directory a licensed therapist?

The Psychology Today directory lists providers who offer legitimate mental health services to the public, including psychologists, psychiatrists, social workers, and counselors.

Many have been licensed by the country or state where they practice; providers whose license or primary credential has been verified by Psychology Today are signified by a “Verified” symbol. Some clinicians or organizations provide services for which their state or country does not offer licenses, such as pastoral counseling. They may be selectively included without the “Verified” seal.

What’s the difference between a psychologist, a therapist, and a counselor?

Therapists, psychologists, and counselors are all licensed mental health professionals. In the US, psychologists have earned a doctoral degree. The terms “therapist” and “counselor” are used somewhat interchangeably, but generally therapists offer longer-term, mental health care, while counselors offer shorter-term care that may focus on one domain, such as marriage, career, or academic challenges.

Clients should consider factors such as insurance coverage and their primary reason(s) for seeking therapy to determine the type of professional best suited to their needs. Someone struggling with mental health challenges such as depression or anxiety, for example, may wish to seek out a clinical psychologist or therapist, while someone navigating career obstacles or marital upheaval may benefit from seeing a counselor who can offer short-term, targeted support.

What type of therapy is right for me?

The type of therapy best suited to a particular individual depends on several factors, including their primary reason for seeking therapy, their preferred timeline (some therapy types last for a set number of sessions, while others are open-ended), and their personality and preferences—some may prefer a more structured approach. For many individuals, multiple types of therapy could provide a good fit.

How much does therapy cost?

The cost of therapy depends on a number of variables, including location and the therapist’s experience and training. On average, a therapy session in the United States could cost between $100 and $200 or more. If you have insurance, the expense of mental health care is typically lower, but it varies based on your insurance plan details and whether you choose an in-network or out-of-network mental healthcare provider.

What are more affordable or low cost therapy solutions?

Many therapists offer sliding scale payments, usually on a limited number of slots, which consists in an agreement between the therapist and a client to pay a reduced rate. Therapists who provide such arrangements often consider the client's income or ability to pay, but the extent of the discount is ultimately at the therapist's discretion. Furthermore, while group therapy may have different goals and benefits compared to individual therapy, it can be a more affordable solution to address certain types of issues.

Is online therapy cheaper than in-person therapy?

Many therapists charge the same amount for online therapy as they do for in-person therapy—though clients may still find this cost-effective if it cuts down on their transportation costs. Health insurance plans often offer equivalent coverage for online and in-person therapy; indeed, in many places, they are legally required to do so. Text-based or on-demand therapy apps may be cheaper than traditional one-on-one psychotherapy; however, the practice may be less effective and is not likely to be covered by insurance.

Is online therapy a good option?

Therapy conducted online can be just as effective as in-person therapy, as long as there is a strong alliance between the client and the therapist. To find a therapist who provides telehealth services to clients in your area, click “Online Therapy” on the directory homepage and search by your city or town or your zip code.

Are therapy sessions confidential?

Confidentiality is a crucial part of the therapeutic relationship. Therapists in the United States are bound by the regulations set out by the Health Insurance Portability and Accountability Act of 1996 (HIPAA), which aims to protect sensitive health information. With very few exceptions, a therapist will only discuss their client with others when the client has given their written permission. The instances in which a therapist would be required to disclose personal information are: if a client poses a danger to themselves or others, if the therapist suspects the abuse of a child or an elderly or otherwise dependent adult, or if they are legally forced to by court order. These exceptions to the confidentiality agreement are usually discussed with a client before their first session.
