We were at a stand still until Detective Mark McDaniel with CT investigative services located our tort-feasor sought. Now our case can proceed. His service is invaluable for that attorney seeking parties when building his case. Thank you Det. McDaniel!

I stumbled upon Mark and Connecticut Investigative Services after our law firm's prior private investigator retired. Mark was very easy to get a hold of and took my call promptly. I advised him of our client's budget and he was very sensitive to our cost concerns. Mark was able to work within my timeline and achieved the desired results promptly and thoroughly.

He was pleasant and professional and I look forward to working with him and his team on our next assignment. I am grateful for finding him and would recommend him and his agency without hesitation.

Outstanding. I spoke to Mark and it was clear he's been through every kind of investigation, even when in my case it's felt like such a dead end. If you feel trapped or don't have a way or someone to turn to, you will feel completely differently after having a good conversation with him and his staff. Don't hesitate, make the phone call, I think you'll be surprised how much of a nudge it can give you towards solving your situation, I feel so much better about my chances and all it took was maybe 10 minutes. Make the call
