Contact Us

We don't answer the phone during counseling sessions, so you may need to leave a message with your number and the best time to return your call. We'll do our best to get back to you by the next business day.

We are currently accepting new clients. If you need a daytime appointment, we can usually schedule that within a week or so. An evening or weekend appointment may take a bit longer to schedule.

To reach Marie Henderson Sima, please call me at 443.613.6233.

If you are more comfortable using email, you can reach me at:

Please be aware that email can't be totally secure, so please don't share sensitive information like your social security number in an email. We are happy to schedule appointments via email, but we do limit the scope of email content to protect privacy.


We're generally open, even when there are a few inches of snow and schools are closed. Please email or text if you're unsure or if you need to reschedule due to weather, or closed schools.
