  • Andaleeb Geloo Esq.

    When I first started practicing law in Fairfax as a brand new attorney, I knew that I would be faced with strong challenges which I was determined to meet head on. Very quickly, a few attorneys stood out to me as being among the best, and they were the ones from whom I sought my own professional development. Decidedly, the attorneys at Dycio Biggs were among them. Courage in the courtroom is the willingness to fight for your client even when you know you could lose and even when it is not the most popular thing to do. This firm takes on difficult cases, in challenging circumstances. The results speak for themselves.

    I have known Mark for more than 13 years through his practice in Fairfax County courts. He is a zealous advocate for his clients. He is a leader in the legal community and often develops innovative and successful defenses for his clients. I have benefited from his wisdom on many occasions and therefore, as his friend and colleague, I strongly endorse Mark Dycio.
