Focused, Individualized, and Effective Care for Depression, Anxiety, and Adult ADHD

Rabjohn Behavioral Institute, PLLC​

1839 Cannon Dr, Ste 101

Mansfield, TX 76063


On August 7, 2023, we added a Nurse Practitioner to our team.  We are so excited to have Michelle Vasquez join us at RBI.  She will work directly with Dr. Rabjohn and our wonderful therapists and life-coach to ensure you are getting the best care possible.

We also have a new therapist, Melissa Gramigna, LPC, who is seeing clients at RBI.  She has close to 20 years of experience with teens and adults.  She would love to meet with you to discuss her therapy approach and what that could do for you.

We are in our new location at 1839 Cannon Drive; across the street from Uptown Cheapskate and behind the new building they are constructing for Dr. Hamm.  RBI now sits about 150 yards off the road behind Mansfield Pediatrics and Mansfield Family Dentistry and behind the two buildings being constructed.

​Please watch the video overview of our services, approach and philosophy of care.

For Existing Patients:

Will my appointment be in-person or virtual?

Things continue to change week-to-week and month-to-month on whether we are open for in-person visits or just doing virtual visits.  We know this can be frustrating and it is frustrating to us as well.  We base our decision on current Tarrant County Covid numbers and whether or not any of our staff or staff family members are sick with covid or the flu. 

Currently, appointments are both in-person and virtual.

Hopefully, for the remainder of 2023, all five providers will be offering either in-person visits or virtual visits.  For example, Dr. Rabjohn typically does in-person visits on Mondays and Thursdays and Friday mornings, then does virtual visit appointments on Tuesdays, Wednesday, and Friday afternoons.  For most instances, we allow you the patient to choose which type of appointment you would prefer.

For Virtual Appointments:

If you choose a virtual visit, you are sent a link via email usually the day before your appointment.  If you do not receive a link, please let the front staff know at 817-539-2282.

Our preference is that you are on a computer and that you have privacy.  

We understand that many will choose to use their cellular phone.  This is fine, but please have headphones or a way to ensure your audio works.  For some reason, many patients have had recent issues with the audio on their phones.

Please do not be driving in your car during your appointment.  Most likely, we will ask you to reschedule if we do not have your full attention or you choose not to pull-over.  This will require a new, scheduled appointment and you will have to pay another appointment fee.  

We also require you to be sitting-up and prepared for your appointment.  For whatever reason, some people feel it is appropriate to be laying in bed for their appointments or still ‘under the covers’.  That isn’t appropriate for a scheduled medical appointment.  Please be awake, alert, and prepared for your visit. We will not do appointments with you lying in bed and you will have to reschedule and pay another appointment fee.

Zero Tolerance Policy:

Several times in the last two years our staff members and providers have been yelled at, cursed at, and also threatened.  Any insulting, negative, or disrespectful behavior towards are staff or providers will result an immediate discharge from our clinic. Any threats of harm to anyone within our office will result in immediate notification to law enforcement.


While we are located in Mansfield, we are very close to Arlington, Fort Worth, Midlothian, Burleson, and Grand Prairie.  However, we are able to see anyone who is a resident of Texas.
