Client Testimonials

“After working with two other lawyers regarding my divorce agreement not being followed by my ex-husband, I found Catherine Miller. More likely, we found each other. I feel connected to Catherine. Professional, smart, and caring describe what I feel about her. She was just what I needed. She saw me for who I really am and not all the accusations from the other party. She got High-Conflict Kids First court-ordered which was so important.  Catherine believed me.  With Catherine’s guidance, I got much further faster in the court process. I needed an aggressive approach and I got it. As difficult as my five years dealing with this situation was, Catherine made me feel supported and good. I would highly recommend Catherine Miller to anyone who needs a lawyer.”

“Right from the start, Attorney Catherine Miller impressed me with her efficient, professional manner which immediately instilled my confidence in her abilities to represent me well with a child support challenge. I needed an attorney who would listen to my concerns, guide me through my options, and make recommendations that produced the desired results. She took the time to educate me well about the legal process and promptly responded to my emails and questions every step along the way. I was never left wondering what I needed to be doing or not doing to help my case. She was prompt and professional when in court and always prepared me well for hearings. Because of Catherine’s capabilities and attentiveness, my case was resolved to my high satisfaction and without undue stress.”

“Jessica has been a savior for me. She is an outstanding attorney and she always had my back. I don’t have enough good things to say about Jessica, the firm, and your paralegals.  I feel blessed to have nothing but the best representation. I can finally breathe.  It has been a long time since I felt this light.”

- A. Saco, Maine

“MillerAsen is truly an amazing firm.  Nobody really ever wants to need and or use a lawyer but my experience with Catherine and Jessica has been positive.  Catherine and Jessica are very professional and prompt in their cases.  They are always on top of their game and very clear on the process in and out of court.  I find them not only on a professional level but a personal one too.  They are caring and kind, not just treating you as a client, but a person and case they care about.  High recommendations.”

- D. Windham, Maine

“I came to know Whitney Lallas at a challenging time in my family life. There was so much uncertainty and anxiety surrounding parental rights and custody and her expertise helped set my mind at ease. Whitney took the time to get to know me, the situation, and the solutions I was looking for. She spent the time listening and offering support and legal advice, but what was most important for me was she knew when to pull back when I became overwhelmed – she instead listed out options for me to process. Whitney also always made sure to not overspend and did not rush to jump steps until it called for it – which was impactful for someone with one income.  Whitney fought for my family to get our situations resolved fully and I would highly recommend her services.”

- L. Naples, Maine

“Thank you very much for representing me in the divorce process.  Your good counsel helped my former spouse and I to reach a settlement that’s fair and reasonable.  I care very much for former spouse and want her to have a secure financial future that’s free of worry.  I think the settlement sets a course to realize that goal and I feel good about it.  I’m grateful to all of you.”

- R. Portland, Maine

“As time goes by I look back at the stress of separation and divorce, and I realize exactly how much Catherine Miller helped me make good decisions and land squarely on my feet. It has been over 4 years since I hired Catherine Miller to help me at the worst time of my life. I am beyond grateful for Catherine’s kind guidance and firm advocacy.

If you have children, Catherine Miller will be completely focused on their well-being. During our initial conversation, she recommended Kids First, a non-profit program from which my children each benefitted. There was no pressure from her to settle on divorce, but in the interim between separation and divorce, she provided an excellent custody agreement that spelled out clarity for living in a co-parenting family.

As a professional, the separation and divorce was overwhelming given my need to balance single parenting and a demanding work schedule. Catherine provided excellent advice related to my personal circumstances. I had no idea how my decisions would impact my future security and she provided outstanding guidance and expertise. Most importantly, Catherine remained a resource to me when a few issues arose years later. She responded within 24 hours and provided insight and clarification on my rights and choices given the new circumstances and the existing settlement agreement. She has always asked me within the first few minutes of any conversation, “and how are the kids?”.

Having experienced it firsthand, I am saddened to think of what families go through during divorce – once the reality of separation hits you, having Catherine Miller as a supportive lawyer can help with the transition into a peaceful and healthy family. Today my life is peaceful and productive. My children are well-adjusted. We consider ourselves a very happy close-knit family.”

“Catherine was recommend to me by Kids First of Maine and she is an outstanding family lawyer. She is extremely professional, knowledgeable, and assertive. While being attentive, Catherine genuinely seems to care about her clients on a personal level. She helped me explore the best possible solutions for my situation and everyone involved, well before we had to go into the courtroom.”

– M. Portland, Maine

“Again, I really appreciate all you have done, your counsel, and your concern for my emotional and financial welfare!  It’s great to have an advocate with your experience and intellectual resources!”

- M. Cape Elizabeth, Maine

“Anytime someone has to engage the services of a lawyer, the stress level is high. We owe Catherine our appreciation, not just for her unflappable and tenacious approach to a steady stream of legal challenges and complexities, but for her steady hand with us, the family. She helped us to find some sense of normalcy in the midst of often overwhelming fear and sadness.

There were times when there were more hands in our lives than we could have imagined. Someone from an agency or a court or any one of a series of therapists would impact my niece’s and nephew’s lives with a slight shift in perspective. Very often it was somebody’s subjective interpretation and not always in the children’s best interest. Catherine was “on it” all, she kept us steady and hopeful.

Catherine is exactly the lawyer we needed in the courtroom. She handled herself with grace a power. Hard combination in my book. She was on point throughout the trial. She walked into the courtroom prepared and everyone knew it. She is honest and demonstrates calm and confidence. At the end of the day, most of what a great lawyer has to do is support a client in doing the right thing. Catherine did all of that and more.

And the outcome! Our entire family will be forever grateful for what she has made possible. With her support and knowledge, we are now on the “other side”. Returning to life that is settled and filled with normalcy. Pretty outstanding accomplishment. If you are needing the services of a lawyer, then I strongly encourage you to consider Catherine.

Equally important in my book is an efficient staff that works behind the scenes. Catherine’s staff is strong and super efficient. Always kind and very respectful whenever we called or needed help. They are wonderful and work well as a team.”

– J. Westbrook, Maine

“Catherine has repeatedly and consistently proven to be a valuable resource, providing candid advice on legal matters, helping to resolve difficult conflicts outside of the courtroom, and offering welcome guidance on co-parenting issues.”

- J. Falmouth, Maine

“I have worked with Catherine for many years, in regards to a challenging ex-spouse, and the custody arrangements we have with our child. Catherine has guided me through some very difficult decisions, while maintaining the upmost respect for my concerns and needs as her client. Her expertise in Family Law, combined with her professionalism and genuine care, helped to give me a strong sense of security. This was very appreciated when dealing with some emotionally charged situations. In addition to explaining the “legal language” to me, Catherine helped me to stay calm and focused when stressful situations arose. When it comes to lawyers, Catherine is the real deal. She sees the whole picture, focuses on your goals, and guides you through the process with a kind heart. During one of the most difficult times in my life, she was always available and willing to listen. I trust Catherine immensely, and would not have wanted anyone else by my side to represent me.”

- S. Cape Elizabeth, Maine

“Employing the services of Catherine Miller was the single best decision I made during my divorce/child custody dispute. Though my case was previously handled by another lawyer , Catherine quickly familiarized herself with the details of my case and moved forward with a defined plan. During a difficult time in my personal life Catherine made me feel at ease when we first met and reassured me each time we corresponded . Catherine’s advice to me throughout this process was dead-on and proved invaluable.  While continually keeping me informed, Catherine kept constant contact with the Guardian ad litem and other entities to broaden her knowledge of my case and to stay current. In the courtroom Catherine’s preparation, efficiency and professionalism were remarkable. My experience with Catherine Miller’s firm has been a positive one and I would encourage anyone in need of family legal counsel to seek her services.” 

- J. Westbrook, Maine

“I highly recommend Catherine to anyone who may need compassionate, experienced, skillful legal guidance and representation. She can make an otherwise unpleasant experience, truly, one that is well organized and focused, and produces the outcomes that you mutually agree upon; not to mention that she is a genuine pleasure to work with.”

- D. Portland, Maine

“Obviously any time someone has to engage the services of a lawyer, the stress level is high.  It’s like all the standard rules of life have disappeared – and there is risk and heartbreak at every turn.  Catherine masterfully provided guidance – readied me for the challenges I would have to live with throughout this painful process.  At the end of the day, most of what a great lawyer has to do is support a client in doing the right thing.  She helped me to understand.  Advocacy is another key facet of Catherine’s approach.  When the rhetoric or temperature would escalate, she demonstrated calm and confidence.  My perspective was never presented as volatile or disrespectful.  There were times when I was bursting with frustration and wanted to respond to attack with my own attacks.  I know this was never easy for Catherine, but she protected me from my own short-term reactions.  I took the deep breaths as she advised.   If you are needing the services of a lawyer, then I encourage you to consider Catherine.  With her support and the support of her firm, I am now on the other side.”

- G. Portland, Maine

“Catherine is not just talented lawyer, she is an amazing person who is easy to work with. The separation from my family was the most difficult experience of my life. The legal system was the last thing I wanted to deal with.  Catherine’s experienced and patient guidance helped me make the best of a rotten situation. She provided me with practical options to give me the best chance of accomplishing my goals. I would call on Catherine again without any hesitation.”

- C. Cape Elizabeth, Maine

“Thank you for your representation of me during my divorce.  People in Maine and the greater Portland area, in particular, who have to go thru this process are fortunate to have your services available to them.  I will recommend you highly to anyone, as your more peaceful/resolution orientated style really is in the best interest of your clients. The process was extremely difficult but I’m glad it’s over and the resolution we got…I think is as good as it can really be.”

- M. Falmouth, Maine

“I approached Catherine late in my divorce process to help me wrap up the final paperwork and process the official filing.  At our first meeting, she came across as extremely knowledgeable and I was impressed at how efficient she was in getting the necessary papers prepared for me and my ex-spouse.   The process was painless, done in less than two hours,  and I didn’t feel I was billed for a dime more than what was put in.  Months later, I needed Catherine’s professional help to come up with an addendum to my divorce agreement.  Her advice was invaluable and she did an excellent job laying out an addendum that had my best interests in mind.  I would (and have) highly recommended her!”
