About PACT
Provider Excellence. Coordinated Care. Time & Cost Efficiencies.
PACT (Physicians Alliance of Connecticut) is a multi-specialty group of independent physicians that have banded together to maintain a private-practice style of healthcare services in the New Haven area. By becoming divisions of PACT, these practices retain and protect their individual cultures and community connections while using shared resources to handle non-medical issues such as billing and technology support.

What our patients are saying
I saw Diane Graham as my first primary doctor after aging out of my pediatrician’s office. She was wonderful and gave me awesome recommendations for little issues that I had that other doctors never bothered to give me! Finally, I am not anxious about doctor visits!

Went to the Ansonia office. Visit was pleasant, didn’t have a wait to be seen, Shanna Gannon, PA was very nice, helpful, and patient with my needs. Highly recommend Dr. Aversa, Shanna Gannon, PA, and staff.
- Dian Ostuno, Google Review
Shanna is wonderful, she is smart and to the point ! She was able to help me diagnose my problem when just about no other doctor I seen prior could do !! I’m currently 5 weeks from a sports hernia surgery and I’m finally going in the right direction! I still have some healing and physical therapy to go but for the first time in a year after 3 surgeries I feel hopeful to get back to work!!!
- Justin Murphy, Google Review
Thorough, knowledgeable, takes time to explain but gets to the point. Would highly recommend.

Dr Ginsburg is amazing. He literally saved my daughters life her Freshman year of college when she was diagnosed with an autoimmune disease. Thanks to him and his amazing staff she is now in remission and thriving. I’m not sure who wrote that his office staff was unfriendly or he has no beside manners because nothing could be further from the truth. Highly recommend!
- Karen Diorio, Google Review
Went to see Dr Ginsburg for a second opinion, have been beyond impressed- I’ll continue my 45 minute commutes to continue with him as my doctor. The staff has been so thorough with making sure I have appointments set up with his office and elsewhere (for testing, referrals etc.) Dr Ginsburg covers all the important aspects related to my GI-health and not just what is bothering me in that moment. I’m grateful for his detailed care, compassion and advocating for my well-being!
