    When it comes to sex, exploring things outside of the norms of society can be hard. Talking about it can be awkward or uncomfortable. Even just thinking about it can be a struggle. When we think about sex, we think about the heteronormative definition, that anything outside of monogamous sex and relationships is wrong. Because this is the norm, a lot of time, it’s unknown that there is a world of other options out there to explore
    such as polyamory, open relationships, serial monogamy, kink, and more. Along the same lines, understanding and exploring one's body can be difficult as well.
    Especially if there has been trauma that can bring up bad memories, flashbacks, or triggers. This can make you feel uncomfortable with your body and even being inside your body.

  • Aileen Castellanos, M.Ed. AMFT
    Registered Associate Marriage and Family Therapist #127239

    Hello! My name is Aileen Castellanos I am a Bilingual Spanish and English-speaking Latina therapist. My interest includes reading books, drinking tea, doing arts and crafts, and binging Netflix. I have six years’ experience working with children, adolescents, adults, and couples. I specialize working with parents of children and teens with neurological challenges, children/teens with neurological challenges, couples with emotional, sexual, and communication difficulties, and individuals with anxiety and/or depression.

    Being a parent of a child with neurological challenges can be exhausting especially when there are a million other things that needs your attention in your life. Do you feel overwhelmed by life with your children or even with your spouse/partner? Unsure how to communicate your needs to your family properly? Are you so tired and exhausted of the same communication loop that gets you nowhere? Feeling empty and numb on the inside? Unsure how to stop those racing thoughts and uncomfortable feelings inside? Do you feel ready to make the necessary changes to better your life?

  • Sharayza Blakemore (Jackson), MBA, MS Couns Psychology, AMFT
    Registered Associate Marriage and Family Therapist #128412

    Sharayza Blakemore, is an Associate Marriage and Family Therapist under the guidance of Dr. Leslie A. Miles. She received her Master’s Degree in Counseling Psychology from California Baptist University and her Master’s in Business Administration (MBA) degree from the University of Phoenix.

    As a mom, wife, friend, and professional, many people rely on us for everything. By the time you meet those requirements, there is not much to pour into yourself; however, remember, before you can pour into others, you must also remember to give YOU attention. Oftentimes, you might feel like you can handle it ALL until one day you can’t, and you are left feeling down, lonely, and TIRED. Does this sound like you? I am here to say, “hold on a little longer my friend, you can be ALL these things,” but remember YOU in the process.

    Registered Associate Marriage and Family Therapist #131006

    Are you sick and tired of being sick and tired? Constantly thinking, “…is this as best as it gets?” or finding excuses as to why you should leave but are too afraid to? Repeating the same patterns over and over again, hoping for a different result? You, your child, or family are struggling emotionally? Seeking help is never easy, however, you find yourself here and that is already something to be proud of. I believe that by creating a safe, warm, validating, and supportive environment, can lead to growth and empowerment over time. If you're looking for extra support and guidance through a challenging situation, or you're just ready to move in a new direction in your life, I look forward to working with you to achieve your goals. I understand how easy it can be to fall into routine patterns, so if you are ready and willing, lets venture through this journey together to foster change.

  • Kilauni Tillett
    Registered Associate Marriage and Family Therapist #133016

     Hi! My name is Kilauni! I pull from a strengths based perspective which means together we will highlight and honor your unique traits, experiences, cultural identity, and skills to empower you on your healing journey. I also enjoy narrative therapies which allows you the control to write the story of your life and how you want to live it. I think the key to any therapeutic environment is to create a calm, warm, and safe space for you to explore your perspectives free of judgment. My job is to support and process with you what the best ways to achieve your goals are and what feels authentic to you. 

    I earned my Master’s degree in Counseling Psychology from California Baptist University with concentrations in both Marriage and Family Therapy and Professional Clinical Counseling. I have worked with children, adolescents, and families in school and clinic settings. I look forward to inviting you to write the life you desire most and supporting you in taking the steps to make it your reality.
