Behavioral Health

With the formation of Mid Atlantic Pediatric Partners, THH now offers behavioral health services, in our office and virtually during this pandemic. Dr. Ari Yares has been treating our patients for over two years, and has been credentialed with most health insurances since August 2020.

We would like to welcome Dyuti Ganesh, our newest member of the MAPP Behavioral Health team.

Dyuti Ganesh – Psychology Associate

Dyuti Ganesh is a recent graduate of the University of Maryland and a registered Psychology Associate. She will be providing individual and group therapy under the supervision of Dr. Ari Yares. She utilizes a relational-cultural approach that prioritizes the client-therapist relationship. Her belief is that the nature of relationships is to grow and thus, her approach involves authenticity, humility, playfulness, acceptance, and respect in working with children and families. She integrates theories that evolve from psychodynamic, cognitive behavioral, and dialectical behavioral modalities along with mindfulness practices in order to facilitate self-awareness and self-acceptance within clients. Dyuti enjoys the blend of Western evidence-based treatments with Eastern mindfulness-based practices to result in a holistic, strengths-based, mind-body approach to mental health and well-being.

Due to testing supply issues, COVID testing through our office is currently only available for symptomatic patients until further notice.


The CDC has approved the Pfizer Covid-19 vaccine for children 5-11 years old. Due to limited allocations from the Maryland Department of Health, we are unable to schedule vaccine appointments at this time.  We expect to receive an update within the  next two weeks. When we receive notification of our next shipment, then we will open our next clinic. If you have already received your first dose at our office, then we have received the allocation for your booster dose and you should keep your second shot appointment.  Please continue to check the THH website, facebook page and portal messages for updates!


Although  the CDC has stated that fully vaccinated people do not need to wear masks in most settings, this does not include healthcare settings. THH Pediatrics still requires all patients and visitors to wear a mask when they come to the office.

    Our CHADIS screening process has changed for Well Child Care (WCC). Please check our CHADIS page and fill out your screen prior to your  well check up to make your WCC experience more complete. 

We have restarted our evening hours on Mondays and Wednesdays, but we will continue to not have Thursday evening and  Saturday morning hours   until further notice. We are seeing well check ups for all ages. THH will continue to schedule telemedicine visits and appropriate sick visits in the office. In addition, please see our latest news section regarding Coronavirus resources for parents.
