Flor G. Client

Pleasure to work with

Maggie is a pleasure to work with and instrumental in working through any environmental matters.
Will P. Client

Trusted professional “tip of the sword”

I called on Maggie Witherup to assist through an environmental pinch point in a time-sensitive negotiation. From my initial call, to the call with the client, to the follow up received to the outcome achieved – Maggie was the trusted professional “tip of the sword” who relied upon – but did not exploit — her relationships with entitlement agencies.

I could not have scripted a better outcome for my client, delivered reliably by someone that knows what they are doing.

This was a good outcome – but was made great – when the same successful outcome was delivered to another client I referred.

Owen R. Client

Responsive, knowledgeable, and detailed.

When my company has a legal issue with an environmental matter, Maggie Witherup is my first call. I trust her completely to help me get it resolved. Whether it’s pertaining to Federal or State law, she’s well-versed in both. Maggie is responsive, knowledgeable, and detailed. I value her expertise as she guides me and my company through an often convoluted bureaucratic process. I highly recommend Maggie Witherup and the Witherup Allen Law firm.

Jim H. Client

Diligent, solution oriented and professional.

Maggie Witherup has been nothing but a pleasure to work with as she always comes prepared, organized and with a client first mentality. I trust Maggie and Witherup Allen Law to put their clients in the best position for a positive and successful outcome.

Ben R. Client

knowledgeable, prepared, responsive

I met Maggie Witherup a number of years ago. My small metal finishing company encountered an environmental issue with the EPA. She came highly recommended by a friendly competitor and did not disappoint. Maggie led our navigation through that challenge and a number of others over the intervening years, including the sale of the business this past July. Maggie was always knowledgeable, prepared, responsive and, not insignificantly, kind. I can recommend her without reservation for any environmental and general legal matters.
