While therapy can be challenging to face, I try to make the process as easy as possible, hopefully even enjoyable.

I am a Licensed Marriage and Family Therapist (LMFT) with 20 years of experience working with individuals who cope with Dissociative Disorders including DID, and also PTSD/CPTSD. My training has been heavily focused on helping people heal from painful experiences while simultaneously deeply learning about themselves.

How will you know when you don't need to come here anymore? We explore together where the client is at in their journey and what is working and not working for them. I then help the Client to identify what they want to have different in their life and collaborate with them to develop the plan of how to achieve it. My focus is on balance and moderation in all areas of life. I work with clients via telemedicine sessions for both talk therapy & EMDR. Please email or call to explore if we would be a good working team.

I allocate my time and practice between two specific and unique issues: one being sexually related problems, the other being OCD. With sexually related issues, they can show up as relationship problems, infidelity, arousal discrepancy, or LGBT matters. Likewise, with OCD, there are many different forms and subtypes: harm, scrupulosity, contamination, sexual, symmetry/order/balance/just right. I am trained and experienced in both fields, utilizing tools and interventions to treat one or the other, and sometimes both.

The decision to engage a therapist is deeply personal and may seem challenging. It is a unique relationship, where ideally, you can be in a safe, empathic environment and talk to someone with in depth psychological training and significant life experience. I offer both to my clients, treating individuals, couples, children, adolescents and families. These relationships have led me to focus on the treatment of: anxiety, depression, relational communications, work place stressors, substance use/abuse, attachment disorders, emotional regulation issues, self image, family systems, ADHD, grief and loss, parenting, obsessive/compulsive behaviors, impulse control, mood disorders and relational conflicts.

Obsessive-Compulsive (OCD) Therapists

How long does OCD treatment take?

Obsessive-Compulsive Disorder (OCD) is often treated on a weekly or twice-weekly schedule, depending on symptom severity and the client’s preferences. Some clients may start to see a noticeable improvement in symptoms in as little as six weeks, but it’s also possible, especially in more severe cases, for treatment to take several months to a year before significant progress is made.

What happens if OCD is not treated?

Some people with OCD, especially those with mild symptoms, may find that they are able to adapt reasonably well to life with the condition, even if their symptoms never resolve completely. However, many people, particularly those whose symptoms are severe at the outset, find that their obsessions and compulsions grow more intrusive with time, making it harder to maintain relationships, hold down a job, or navigate the world successfully.

Are there medications for OCD?

Medication can be used to treat OCD. The class of drugs most often prescribed are selective serotonin reuptake inhibitors, or SSRIs, which include fluvoxamine (under the brand name Luvox), fluoxetine (Prozac), and sertraline (Zoloft), among others. In cases of treatment-resistant OCD, other classes of medication, such as tricyclic antidepressants or atypical antipsychotics, may be prescribed. Medication is frequently used in conjunction with therapy.

Can OCD come back after treatment?

Yes. Major life transitions, periods of stress, or other factors can cause symptoms to return or, if they were never fully eradicated, to ramp back up in intensity. For some, these relapses are brief and do not require additional treatment; identifying specific triggers and practicing the skills learned in therapy can help speed their course. For others, returning to therapy for a brief period can help address the underlying stress and strengthen coping mechanisms.
