My wife's debit card was compromised or hacked over 2 weeks ago. Tide Mark lied to her and said they were sending her one in the mail. Which they didn't. I'm 67 years old I've never seen such poor customer service out of any company I ever dealt with. Then they say they overnighted to us and that was a lie also. So before you use tide mark check their credit ratings and reviews and I'm sure you'll change your mind if you have half a brain. We are still waiting stop lying to us and be professional

This is Andy Wayson writing this review. I'm using my girlfriend, Melanie's Google account since I don't have one. I recently bought a used RV. During the process I needed to secure financing. I quickly became frustrated as I searched several online Companies. They all wanted me to fill out online applications. I'm old school and don't like doing it that way. None of them had a number to call and speak with a human, until I found Tidemark FCU in Seaford Delaware. I called the number and Pamela Varvaro answered. She had a very friendly voice and told me they handled RV loans. When I asked her about their terms, she got straight to the point. To my joy they were the best I had heard over anyone else. Pamela made the process super simple and guided me through it like a Pro. She made my sale streamline and it was great working with her. I'm a customer for life and have told others about how impressed I was with her and Tidemark FCU. If you need everyday banking or a loan of any type. I highly recommend Tidemark FCU !!! Thanks Pamela Varvaro for your customer support. As a business owner , I can assure those above you, that you're representing Tidemark with the upmost competence... Captain Andy Wayson

I wanted to say thank you to Ebony Hopkins for all of her kindness and assistance. Ms. Hopkins went out of her way to provide exceptional service to my family in our time of need. Her patience and empathy provided comfort and support - especially for my mother. Thank Ebony for all you have done for us.

My experiance with Tidemark was very good. I always delt with Rehoboth branch. 5 stars for them. But the other branches have been difficult to deal with. Making bank transfers to them from PNC are often denied for verification of funds. The app is buggy. Often, can't access, and when i do, it states that there is no information available. I am transferring all my funds to PNC bank. They are much more useful and helpful. I am very disappointed in how difficult things have become with Tidemark.
